Watermark PDF FAQs
Can I add a text watermark?
Yes — enter the watermark text and apply it to the PDF, then download.
Is watermarking private?
Yes. The PDF never leaves your device.
Is watermark PDF free?
Yes — free with no account.
Do you upload my files?
No. GroundPDF processes files entirely in your browser with WebAssembly. Files never leave your device — nothing is uploaded to a server.
Is it free?
Yes. Free to use with no account and no daily limits.
Which devices and browsers work?
Any modern browser with WebAssembly support: Chrome, Firefox, Safari, and Edge on desktop or mobile.
How is this different from iLovePDF or Smallpdf?
Those tools upload your files to the cloud. GroundPDF runs on your device (on the ground, not in the cloud), so your documents stay private by design.
