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