Add Watermark to PDF

Overlay text or image watermarks with full control over opacity, rotation, and tiling.

Guide & FAQ

About this tool

Stamp DRAFT, CONFIDENTIAL, or your brand logo across every page - text or image watermarks with opacity, rotation, position, and tiled mosaic modes - before sharing review copies externally. JoyPDF applies watermarks locally in your browser without uploading contracts or unreleased creative PDFs. Free, no account. Watermarks sit above or beneath page content depending on layer setting; they deter casual sharing but aren't forensic DRM.

What you get
  • Modes: text watermark or image file overlay - PNG logos with transparency work best.
  • Opacity: 0-100% - faint 'Draft' vs bold diagonal CONFIDENTIAL.
  • Rotation: angle control for diagonal stripes across page.
  • Position: centre, corners, or tiled mosaic repeating pattern.
  • Layer: over content or under text - under keeps body readable, over more visible deterrent.
  • Limits: watermarks aren't encryption - recipients can still screenshot; use Protect PDF for access control.
When to use
  • Marking draft contracts sent to clients for comment before execution.
  • Branding internal PDFs with company logo on every page for partner distribution.
  • Labelling review copies SAMPLE across pitch decks leaving master clean.
  • Discouraging casual forwarding with visible CONFIDENTIAL diagonal text.

Common questions

Can I watermark with my company logo image?
Yes - switch to image mode and upload PNG or JPG logo. Transparent PNG avoids white box halos. Scale via size controls; tiled mosaic repeats logo across page for anti-copy aesthetic. Keep file size reasonable - huge PNGs inflate PDF. Test print in grayscale if logo relies on colour contrast.
Will watermark block text from being copied?
Over-layer watermarks visually cover content but don't encrypt text underneath - determined users can copy text or remove watermark in editors. Combine Protect PDF password and watermark for stronger policy story. Redact PDF for true removal of secrets. Watermark is deterrent and labelling, not access control alone.
Can I apply different watermarks to different pages?
Page range from/to limits scope - e.g. watermark pages 2-50 but not cover. Single text/image per export pass - run twice with different ranges for section-specific marks if needed. Mosaic mode applies same pattern on selected range uniformly.
Is my PDF uploaded when adding watermarks?
No. Overlay composition runs in-browser. Unreleased creative PDFs and term sheets stay local during marking. Download watermarked copy only to intended recipients.
Text vs image watermark - which to choose?
Text is fast for DRAFT, CONFIDENTIAL, internal use strings - font and rotation customise look. Image suits brand logos and certification marks PNG assets. Text stays sharp at any zoom; image may pixelate if low-res logo blown up. Diagonal semi-transparent text is classic legal draft convention.
Does watermark reduce PDF quality?
Watermark adds vector text or embedded image overlay - minimal impact on underlying page quality unlike flatten-to-image export. Extreme opacity over content can obscure readability - balance legibility vs visibility. Under-layer watermark keeps text clearer while showing mark behind.
