Terms of Use

Every converter here is free, full size, no account. Photos convert in your browser and never leave it, except camera RAW files and SVG tracing. Those, like video, audio and e-books, need our server, and we delete them right after.

Last updated: 8 October 2026

By using ConvertNinja you agree to these terms. They are meant to be short and fair.

Ordering online

How you buy. You choose a pass (30 days or 24 hours) and press the buy button. You are sent to our payment provider Stripe, where you enter your e-mail address, choose a payment method, tick the box to accept these terms and ask us to start your pass, and press Pay. The contract is concluded when your payment succeeds; we then show your pass and e-mail you a confirmation. A 30-day pass costs €5 and a 24-hour pass costs €3, both including VAT.

Correcting mistakes. Before you press Pay, the Stripe page shows what you are buying and the total, and you can change your e-mail address or leave with the back arrow or your browser's back button. Nothing is charged until you press Pay.

Storage and access. We keep a record of your purchase (order reference, amount, date and time) in our payment and pass records, but we do not store the concluded contract as a separate document for you to retrieve. Your confirmation e-mail contains the order reference, the price, the key terms and the withdrawal information: please keep it. These terms stay available on this page, and you can ask us at info@shinobitools.com if you need them again.

Language. The contract can be concluded in English.

Use it on your own photos

Use this tool on photos you own or have permission to convert. You are responsible for what you convert and what you do with the result.

The service is free and provided as is

No liability

To the extent permitted by law, ConvertNinja and ShinobiTools are not liable for any loss or damage arising from use of the tool.

Acceptable use

Do not use the tool to break the law or to infringe others' rights, and do not attempt to abuse or overload the service.

What we don't do with your files

Photos, PNGs, WEBPs, JPGs, BMPs and GIFs are converted entirely inside your browser: they are decoded, re-encoded and downloaded again without ever being sent anywhere, so there is nothing on our side to look at, keep or lose. Video, audio, e-books, camera RAW files and SVG tracing are the exception: those need real processing power, so they go to our own server, get converted there, and are deleted immediately afterwards. We don't inspect, share or use the content of any file you convert, on either path, for anything beyond producing the result you asked for.

Third-party services on this site

Two outside services are involved in running ConvertNinja. Advertising is served through Google AdSense, which may set its own cookies and use its own data practices. See our Privacy Policy for how that works. Payments for the optional pass are processed by Stripe, and ShinobiTools is the seller; we never see or store your card details ourselves. Using ConvertNinja means accepting that these two services operate under their own terms alongside ours.

Changes to these terms

We update this page when the tool or the service around it changes, a new format, a new limit, a new payment detail, not on a fixed schedule. The date at the top of this page always reflects the version that applies. Continuing to use ConvertNinja after a change means you accept the updated terms; if a change is significant, we will make the difference obvious rather than bury it in a rewrite.

If part of this doesn't hold up

If a court decides one clause here is unenforceable, the rest of these terms still stand. We would rather have most of this document keep doing its job than lose it all over a single line.
