How it works

Your file never leaves your computer. There's no server receiving it, no database storing it, nobody watching what you upload.

1. Your file2. Your browser3. WatermarkedMARK
Everything happens in your browser. Nothing goes through any server.
  • No server uploads

    Not ours, not anyone else's. Your file stays where it is.

  • We don't measure your content. We only measure visits if you accept.

    Analytics load only with your explicit consent. Your files remain invisible to us.

  • We don't see your content

    We never know which file you upload or what's inside it. Impossible.

  • Works offline

    Once the page is loaded, you can disconnect from the Internet. The watermark is applied just the same.
