Frequently asked questions

What visibility should I choose?

Around 15–25% is best for a large diagonal or repeated watermark: readers can see the mark without struggling to read the page. A small bottom label can be stronger because it sits in the margin.

Is this watermark impossible to remove?

No watermark should be treated as absolute security. A drawn text watermark discourages casual reuse and clearly identifies a document, but a determined expert with PDF editing software may alter it. Use passwords and controlled sharing for highly sensitive files.

Can I use Urdu, Arabic or other non-English text?

This lightweight tool uses a standard PDF font designed mainly for English/Latin letters, numbers and common punctuation. Urdu or Arabic watermarks may not render correctly, so English text is recommended.

Can I watermark only the cover?

Yes. Set Pages to “First page only”. All later pages remain unchanged in the downloaded copy.
