How to deposit your first file

From the homepage, drag and drop your file into the deposit area, or click to select it from your computer.

Your browser then computes the file's fingerprint locally, on your machine — the file itself is never transmitted. Only 32 bytes are sent to be timestamped.

Enter a title and description to identify your deposit, then confirm. You don't need to create an account to make this first deposit and see the result.

No sign-up is required to obtain and keep your certificate: this first deposit is free, anonymous, and unlimited, and remains valid and verifiable for life, independent of any account. If you create an account afterward, your next deposits will benefit from a personal tracking space, with three free deposits to try the platform. Intellectual property insurance and legal support in the event of an intellectual property dispute only become active with a paid subscription, starting at €16/month.
