Files never leave your device

Your PDF is processed in this browser tab. Files never leave your device, and mypdf.space does not receive uploads. No account, no watermark, no server-side copy.

Limits worth knowing

  • Text watermark overlay — not a invisible forensic watermark.
  • Does not replace proper redaction of sensitive content.

Frequently asked questions

  • Can I watermark a PDF for free?
    Yes. Add text across pages here with no account or watermark on the tool itself.
  • Does watermark upload my PDF?
    No. Stamping runs in your browser.
  • Should I watermark instead of redact?
    No. Watermarks label a file; they do not remove secrets. Use Redact for permanent removal.
