Add Watermark FAQ
Short answers to common questions.
Can I use my logo as a watermark?
Yes. Choose Image and pick a JPG or PNG file. Transparent PNG logos keep their transparency.
Can someone remove the watermark?
The watermark is drawn on top of each page but is not locked, so a person with a PDF editor could remove it. Treat it as a visible label, not as security.
Does it work with Urdu, Arabic or Chinese text?
Yes. Text that the standard PDF font cannot show is added as a sharp image instead. English and other Latin-script text is added as real text.
Can I watermark only some pages?
Yes. Type pages and ranges such as 1-3, 8 under “Pages to mark”, or leave it empty to mark every page. The watermark can sit once in the center or repeat across the page.
Supported files and current limitations
Works with ordinary, unlocked PDFs. PDFs with fillable form fields or signature permissions are refused rather than changed. Password-protected and damaged files are refused too.
Your PDF is edited directly instead of being rebuilt, so bookmarks, links, attachments and accessibility tags stay in the new file.
The watermark is drawn over the page content. Text in scripts the standard font cannot show (for example Urdu, Arabic, Hindi or Chinese) is added as an image. Images must be JPG or PNG.
Processing stays on your device with no cloud fallback. Very large files can exceed your device’s memory. Your original files are never changed.
