Terms

In force from 5 November 2026.

These terms are the agreement between you and the operator of Universal Conversion: a sole proprietorship under Swiss law, trading as “Universal Conversion”, Route des Arsenaux 27, 1700 Fribourg, Switzerland (“we”, “us”). It covers your use of universalconversion.ch (the “service”). The operator’s name and contact details are on the legal notice page.

By using the service you accept these terms. If you buy a subscription, you accept them again at checkout, together with the subscription terms in sections 6 to 10.

If you live in the EU or EEA and use the service as a consumer, you also have the rights the law of your country gives you, and nothing here takes them away (see section 17).

1. What the service is

Universal Conversion converts files between formats, and lets you edit photos, documents (PDFs, text documents, spreadsheets, slides and notes) and video, and transcribe speech.

Everything happens in your browser. The tools are downloaded to your browser and run on your own device. Your files aren’t uploaded to us and never leave your device. That has three consequences you should know about:

• Your device does the work. How fast it runs, and how large a file you can handle, depends on your device, its memory and your browser. A file that is too big for your device may fail, even on a paid plan.
• We don’t have a copy of your file. If something goes wrong, we can’t recover it for you. Always keep your original.
• You need a current browser. Recent versions of Chrome, Edge, Firefox and Safari on desktop and mobile. Some formats depend on what your browser itself supports. For example, H.264, HEVC and AAC are handled by the browser’s own codecs, so a conversion your browser can’t do will be refused, and the site says why. AI tools work best on devices with a recent graphics processor.

The AI tools download their engine and model from this site the first time you use them, and your browser keeps them afterwards (see What we store).

The open-source components the service uses, and their licences, are listed on the Licences page. Nothing in these terms limits the rights those licences give you.

2. Using it for free

You can use the service without paying, within daily limits:

• The day. The count resets at midnight UTC.
• Free limits by room. The same with or without a free account: Convert, files up to 500 MB; Video, films up to 1080p and 30 minutes; Music, exports up to 48 kHz and 30 minutes, with up to 4 tracks without an account and 8 with a free account; Transcribe, recordings up to 30 minutes; Photo and Docs, no size limit. A subscription lifts them.
• What counts. Each file you get out of the service counts as one: a converted file, an exported photo, an exported video, and a document, sheet, slides or PDF you download. A zip counts as one file, however many files are inside it. A transcription counts once, when it finishes; saving its text or subtitles, in any format, does not count again.
• What never counts. Opening and editing; the editors keeping your work in your browser as you go; printing, including printing to PDF (except a document carrying a signature, below); copying text; saved edit and look settings in Photo; a still frame saved from Video; and adding a finished transcript to its video.
• Failed files. A file that fails or is stopped before you get it isn’t counted.
• Files that need a subscription. Every tool can be used for free on screen, but these files can only be saved with a subscription: a document carrying a drawn or typed signature, including printing it; several files converted or exported at once; a video above 1080p or longer than 30 minutes; an upscaled video; a 16-bit TIFF photo; music exported as stems, as an album, above 48 kHz or longer than 30 minutes, or from a session with more tracks than the free limit; and a transcription of a recording longer than 30 minutes.
• Shared networks. To keep the free tier fair, there is also a daily ceiling per network: 6 files without an account, and 40 by free accounts. If many people share one connection, the ceiling can be reached before your own limit.

We may change the free limits at any time. A change takes effect when it is shown on the site. The free service is provided as it is, without any promise that it will stay available in its current form.

3. Accounts

• The basics. You need an account to subscribe. Use a real email address you control and keep your password to yourself. You’re responsible for what happens under your account.
• Confirming your email. A free account gets its higher limit once you confirm your email address.
• Minimum age. You must be at least 16 to create an account. To buy a subscription you must be at least 18, or have the consent of a parent or guardian.
• One account each. One person, one account. Creating several accounts to get around the free limits isn’t allowed, and neither is using a school address that isn’t yours for the student plan.
• For one person. An account and its plan are for you alone, not for sharing with other people, a team or a company. You can be signed in on up to 3 devices at once; signing in on a fourth signs out the one used longest ago.
• Deleting your account. You can delete your account at any time from the account page (Delete account), or ask us to by writing to contact@universalconversion.ch. A subscription is cancelled first. Deleting the account doesn’t refund the current period, except as section 9 says.

4. Your content

• Your files are yours. We claim no rights in anything you convert, edit or create, and we never receive it.
• You’re responsible for what you process. Make sure you have the right to convert and edit the files you use. Because processing happens on your device, we don’t see, check or store your content.
• Signatures. The signature tool places a picture of your signature, drawn or typed, on a document. It is a simple electronic signature, not a qualified digital signature, and nothing in the file proves who signed it or that it was not changed afterwards. It is fine for most everyday agreements, but it does not meet a legal requirement for a handwritten or written-form signature (in Switzerland, for example, guarantees, assignments of claims, lease terminations or non-compete clauses). We don’t check what you sign.
• AI tools. Transcripts, background removal, upscaling and the other AI tools can make mistakes: check a transcript before you rely on it. Subtitle translations are made by a machine: they can be wrong, they are not certified translations, and you should check them before you publish them or use them for anything official. If you publish an AI-edited picture or video of a real person, the law where you publish may require you to say so.

5. Acceptable use

Don’t:

• use the service for anything illegal, or to process content that is illegal where you are, such as material that infringes someone else’s rights or exploits children;
• get around the free limits or the payment system, for example by automating requests, creating multiple accounts, deliberately resetting the identifiers we use for counting, or tampering with the requests the site makes to our server;
• attack, overload or probe the service or its servers, or try to get into other people’s accounts;
• resell or offer the service, or access to a paid account, to others as your own service.

If you do, we may suspend or close your account (section 14). This section doesn’t limit your rights under the open-source licences mentioned in section 1.

Open-source parts you may change. Some parts of the service are licensed under the GNU Lesser General Public License, among them the FFmpeg library that converts video and audio. Nothing in these terms forbids you to modify those parts for your own use, or to reverse-engineer them to debug such modifications, and you may replace them with your own build. Their source code, and how to rebuild them, are on the Licences page.

6. Subscription: what you get and what it costs

A subscription removes the daily limit and the file-size limit set by us, and lets you save the files listed in section 2 as needing one, for as long as it is active.

The currency is chosen from the country your connection appears to come from.

Prices include any VAT or sales tax due in your country. You pay the price shown, nothing more.

Gifted plans. We may give you a plan as a gift. It includes what a subscription includes and costs you nothing. It never renews: it ends on the date we told you, or when you start a subscription, which then takes over. As nothing was paid, there is nothing to withdraw from or refund. We may end it early for the reasons in section 14.

Student plan. If you study or work at a Swiss university, university of applied sciences or teacher college whose email addresses are on our list (shown at universalconversion.ch/students), you can have a plan for free: it includes what a subscription includes and costs you nothing. To get it, you show us that you can receive email at your school address: we send a link to that address, and the plan starts when you press “Start the student plan” on the page it opens. It runs for one year from that day. Before it ends we email the school address a link to keep it for another year; if you don’t use it, the plan ends and your account carries on as a free account.

One school address can be used for one account at a time; if you use it for another account, the plan moves to that one. The plan is for you alone, like any plan (section 3). As nothing is paid, there is nothing to withdraw from or refund. If you also pay for a subscription, the subscription is not changed by the student plan: you can cancel it as section 8 says. We may change the list of schools, and we may end the student plan offer at any time; a student plan already running then continues until its end date, unless we end it early for the reasons in section 14.

7. Billing and automatic renewal

• Paying. You pay in advance, through Stripe, for each period: monthly or yearly.
• Automatic renewal. Your subscription renews automatically at the end of each period, for the same length and at the same price, and Stripe charges your payment method, until you cancel. A price can only change as section 12 says: never by silence.
• The yearly plan after its first year. Once a yearly plan has renewed, you can end it at any time with at most one month’s notice, and we refund the part of the year you won’t use, in proportion to the days left (section 8). A plan that became yearly by a change from the monthly plan has its first year from the change.
• Changing plan. You can change between the monthly and the yearly plan from Account → Manage billing. A change to the yearly plan takes effect at once: you pay the yearly price, less the unused part of the month, and a new year starts that day. A change to the monthly plan takes effect at the end of the year you’ve paid for. We confirm each change by email. A change starts a new withdrawal period (section 10).
• Yearly reminder. For yearly plans we email you 30 days before each renewal, with the date, the price and a link to cancel.
• If a payment fails, Stripe will retry it, and your account may lose the subscription’s benefits until the payment succeeds. If it can’t be collected, the subscription ends.
• Promotion codes. If we offer you one, its terms are shown when you use it.

8. Cancelling

You can cancel at any time with “Cancel contracts here” on the contract page, linked from every page as “Cancel or withdraw”. You don’t need to sign in. We confirm your cancellation by email straight away, with the date and time we received it and the date your plan ends. You can also cancel from Account → Manage billing.

• When it takes effect. The cancellation takes effect at the end of the period you’ve already paid for. You keep the subscription’s benefits until then, and you won’t be charged again.
• A yearly plan after its first year ends one month after you cancel, or at the end of the year if that is sooner, and we refund the unused part of the year, in proportion to the days left, to the payment method you used.
• Partial periods. Apart from that, we don’t refund the rest of a period when you cancel, except as section 9 says.
• By email. You can also cancel by writing to contact@universalconversion.ch from the address on your account.

9. Refunds

If you’re not happy, you can get your money back in full within 14 days of your first payment for a subscription, and back in full what a plan change charged within 14 days of the change. Use the contract page (section 10) or write to contact@universalconversion.ch. No reason needed. This applies to everyone, wherever you live. After 14 days, and for renewals, we don’t refund partial periods, except where the law requires it or where we failed to provide the service.

In any case, if the service doesn’t work as described and we can’t fix it within a reasonable time, you can end the subscription and get a refund for the period you couldn’t use. This doesn’t affect any other rights you have by law.

Refunds go back to the payment method you used, normally within 14 days.

10. Right of withdrawal (consumers in the EU and EEA)

If you are a consumer living in the EU or EEA, you have the right to withdraw from the subscription contract within 14 days without giving any reason.

The withdrawal period ends 14 days after the day the contract was concluded, which is the day you completed checkout.

Changing plan. A change between the monthly and the yearly plan (section 7) starts a new withdrawal period of 14 days, from the day the new plan begins: the day of the change for a change to the yearly plan, and the end of the year you’ve paid for for a change to the monthly plan. If you withdraw in that period, the subscription ends and we refund everything you paid since the change. Within 14 days of the day you completed checkout, a withdrawal still refunds everything. The email confirming the change gives the date the new period ends.

How to withdraw. Tell us clearly that you want to withdraw. Use any of these:

• the “Withdraw from contract here” function on the public contract page (linked from every page as “Cancel or withdraw”, no sign-in needed), which is available throughout the withdrawal period;
• an email to contact@universalconversion.ch;
• a letter to Universal Conversion, Route des Arsenaux 27, 1700 Fribourg, Switzerland.

You can use the model withdrawal form at the end of these terms, but you don’t have to.

What counts. It is enough to send your message before the 14 days end. When you use the withdrawal function, we’ll confirm receipt by email straight away.

Effects of withdrawal. If you withdraw, we’ll refund all payments received from you (after a plan change, all payments received since the change) without undue delay, and at the latest within 14 days of the day we’re informed of your decision. We’ll use the payment method you used, unless you expressly agree otherwise. You won’t pay any fees for the refund.

Starting straight away. At checkout you ask us to start the subscription immediately, during the withdrawal period. That doesn’t take away your right of withdrawal, and we refund in full whatever the reason.

11. Changes to the service

The service is software we keep improving. We may add, change or remove features, formats and tools, for example to fix problems or security issues, to keep up with browsers and devices, because a third-party component changes, or for legal reasons, including patents and licences.

If a change during your subscription makes the service clearly worse for you, beyond a minor change, we’ll tell you in advance. You can then end the subscription free of charge within 30 days of the change and get a refund for the unused part of the period you paid for.

This doesn’t limit any right you have under the law of your country.

12. Price changes

A price never changes during a period you’ve paid for, and never by silence.

• When. A new price can apply only from a renewal, and we tell you by email at least 30 days before it (60 days for the yearly plan), with the old and the new price and the reason.
• Only with your yes. Wherever you live, a new price applies only if you accept it, with the button in that email. If you don’t, your plan simply ends at the end of the period you’ve paid for, and you are never charged the new price.
• Cancelling instead. You can also cancel at any time before the renewal (section 8), and nothing more is charged.

13. Availability

We work to keep the service available, but we don’t guarantee that it will always be available, uninterrupted or free of errors.

Because the work runs on your device, it keeps working even when our server is briefly unreachable, except for the free-limit check, signing in, payments, and the first download of a tool.

We may interrupt the service for maintenance, and we’ll try to keep that short.

14. Suspension and termination

• By you. You may stop using the service and delete your account at any time (sections 3 and 8).
• By us, for misuse. We may suspend or close an account, or block access, only for a serious or repeated breach of section 5 (for example automating requests or creating accounts to get round the free limits, attacking the service, or reselling it), or of the rule in section 3 that an account and its plan are for one person (for example sharing it with other people, a team or a company), or where the law requires it. We’ll tell you the reason, and where reasonable warn you first and give you a chance to explain.
• If we close a paid account for sharing, we keep the payment for the month under way, as payment for the month the service was available to you, and refund any later months you’ve already paid for, in proportion. On the monthly plan, nothing is refunded for the month under way. On the yearly plan, we refund the part of the year from the end of the current month.
• If we close a paid account for another breach, we refund the unused part of the period, unless the law allows us to keep it for the breach.
• By us, closing the service. We may end the service as a whole with at least 60 days’ notice to subscribers, and refund the unused part of any period paid.

15. Liability

• What we can’t exclude. We’re liable without limit for damage we cause intentionally or through gross negligence, and wherever the law doesn’t allow liability to be limited, including for injury to life, body or health.
• Slight negligence. For slight negligence we’re liable only if we breach an obligation that is essential to the contract (one that makes the service possible at all and that you may rely on), and then only for the damage typical of such a breach and foreseeable when the contract was made. Any further limit applies only as far as the law allows.
• Your files. We aren’t liable for loss of your files or data on your own device. Keep your originals and backups: we never have a copy that could be restored.
• Mandatory rights. For consumers in the EU or EEA, this section doesn’t limit your legal rights if the service doesn’t conform to the contract, or any other right that the law of your country doesn’t allow to be limited.

16. Changes to these terms

We may update these terms, for example when the service or the law changes.

• For account holders: we’ll email you about important changes at least 30 days before they take effect.
• For subscribers: if you don’t agree, you can cancel before the change applies to you. If the change is to your disadvantage, you can also end the subscription and get a refund for the unused part of the period you paid for.
• Otherwise: the version published on the site applies from its date.

We won’t change the price or reduce the main features of a running subscription by changing these terms, except as sections 11 and 12 allow.

17. Applicable law and courts

• The law. These terms are governed by Swiss law. If you are a consumer, this does not deprive you of the protection of the mandatory law of the country where you habitually live.
• Courts, if you are a consumer: you may sue us in the courts of the country where you live, as well as in Switzerland, and we may sue you only in the courts of the country where you live. Nothing here makes a Swiss court the only one for consumers.
• If you use the service for business: the courts of Fribourg, Canton of Fribourg, have exclusive jurisdiction.

18. Other things

• Contract language. The contract is concluded in English.
• Stored terms. We store these terms and send you the full text of the version you agreed to, by email, when you subscribe and when you change plan. All versions remain available on request.
• Severability. If a part of these terms is invalid, the rest still applies.
• Transfer. We may transfer this contract to another business that takes over the service, for example a company the operator founds to run it (such as a GmbH/Sàrl), if your rights aren’t reduced. We’ll tell you at least 30 days in advance by email, and you may cancel before the transfer with a refund of the unused part of any period you paid for.

How a subscription is concluded

1. Create an account with your email address and a password, and confirm your address from the email we send.
2. Choose a plan: monthly or yearly. The price in your currency is shown before you continue.
3. On our checkout page (“Subscribe”): check what the plan includes, its price per period with taxes, the renewal and how to cancel, all shown directly above the button; accept these terms; tick the box asking us to start the subscription straight away (you keep your right of withdrawal); and press “Subscribe with obligation to pay” (in German “Zahlungspflichtig abonnieren”, in French “S’abonner avec obligation de paiement”). Pressing it is your binding order.
4. Payment. Stripe’s secure payment page then opens to take your payment details, and your bank may ask you to confirm the payment (3-D Secure). The subscription is sold to you through Link, Stripe’s merchant-of-record service, which collects the payment and any VAT or sales tax and sends you the receipt and the invoice; your card statement shows LINK.COM*. Link’s own terms for purchases sold through Link apply to the sale and the payment: link.com/terms. We provide the service itself, under these terms.
5. Confirmation. You return to the site, which shows that your subscription is active, and you receive a confirmation email from us with these terms, and a receipt from Stripe.

You can correct any input error before you press the order button: go back, change the plan, or edit the fields. Until you press it, nothing is ordered or charged.
