Stamp a file

Drop any file, add a title and names if you like, and download a signed certificate that it existed today.

Get a signed timestamp for a song, a beat, a project or any other file.

  1. Open Proof of creation.
  2. Drop a file, or press Choose a file. Its fingerprint shows under its name. Click it to copy it.
  3. Optional: open Title and names to add a title and who made it. They go on the certificate exactly as you type them, and nobody checks them.
  4. Press Stamp. The time appears once the authority has signed.
  5. Press Download certificate.
Nothing is kept on our side. Download the certificate before you leave the page.

What's in the certificate

The download is a zip with three files:

  • a PDF certificate, the readable record
  • the exact text that was stamped
  • the authority's signed timestamp

Keep the zip with the file it covers. You need both to check it later.

Limits

Without an account you can stamp ten files a day, and five an hour.

Save the song to Aden

For audio files, press Save to Aden to upload the song as a track. Every version you upload there is stamped by itself, with its credits.
