Frequently asked questions
Can the watermark be removed later?
The watermark is drawn onto the page content, so it cannot be removed with a simple click. Keep your original file if you need a clean copy.
Is Watermark PDF free?
Yes, completely free with no daily limit and no sign-up.
Are my files safe?
Your files never leave your device. Everything happens inside your browser, so nothing is uploaded to our server.
Is there a file size limit?
Files up to 200 MB are accepted. Very large files may be slow on older phones because your own device does the work.
Does it work on my phone?
Yes. Watermark PDF works in any modern browser on Android, iPhone, Windows, Mac and Linux.
