Save the watermarked PDF

Private by design
Your PDF never leaves your device.
Watermark PDF runs inside your browser tab. The file you choose is read from your device, processed there, and the result is saved back to your device — it is never uploaded to a Pyrbit server, so there is no copy to keep or delete.
Processed in your browser
The Pyrbit PDF engine runs on your computer or phone, not in the cloud.
No upload
Your document isn’t sent anywhere — not to us, and not to a third-party converter.
Sign-in is for your plan only
Your Google account keeps track of your free daily document and Pyrbit Pro. It never gives us your files.

FAQ
Watermark PDF questions.
Can a watermark be removed?
A text watermark is added to the page content and can’t simply be switched off, but determined people with editing software may remove it. For stronger protection, also add a password.
Will the watermark hide my text?
Not with a low opacity — around 20–30% keeps the document readable while the mark stays visible.
Can I watermark only some pages?
The web tool watermarks every page. Extract the pages you want, watermark them, and merge them back if needed.
