Add Watermark to PDF
Add a text or image watermark to PDF pages locally without uploading the file.
Local fonts support Arabic and Latin; upload a suitable font for other scripts.
Safe image up to 10 MiB, 8,192 pixels per side and 36 MP. Large images are reduced to 2,400 pixels.
Leave blank for all pages, or enter e.g. 1,3-5.
Marks shrink when needed to fit inside the visible page, accounting for cropping and rotation.
A watermark does not redact or encrypt content. Original text and form fields stay usable. Saving rewrites the file and invalidates existing digital signatures.
All files and fonts are processed on your device. Changing settings clears the previous result; apply again before downloading.
