Questions
Can the watermark be removed?
The text is added on top of each page’s content. Someone with PDF editing software could remove it, so it’s a visible label rather than security.
Are my files uploaded to a server?
No. UserPDF runs entirely in your web browser. Your files are read and processed on your own device and are never sent to us or anyone else. You can even disconnect from the internet after the page loads and the tools keep working.
Is it free?
Yes. UserPDF is free to use with no sign-up and no watermark on your files. It’s supported by ads.
