Security and privacy

Your file is processed right here in your browser.

The code that does the work runs in your browser, so your document never leaves your phone or computer. Nothing is uploaded and nothing is kept after you close the page. You can check: once your file is open, switch on airplane mode and the tool still finishes.

Frequently asked questions

Can I write the watermark in Hindi or Marathi?
Yes. Devanagari and other scripts are supported, using the fonts on your device.
Is my file uploaded anywhere?
No. Your file is processed by your own browser on this device. It is never sent to a server, and nothing is kept after you close the page.
Can I use a password-protected PDF?
PDFs that only block copying or printing open normally. A PDF that needs a password to open cannot be used here: remove the password with the app that set it, then try again.
