Question 1

Can I add a text or image watermark to a PDF?

Accepted Answer

Yes. This tool supports both text watermarks (customizable font, size, color, rotation) and image watermarks (PNG, JPG). You can place them anywhere on the page: center, top, bottom, or with custom X/Y coordinates.

Question 2

Is my PDF uploaded to a server?

Accepted Answer

No. The watermarking runs entirely in your browser using pdf-lib. The file never leaves your device, ensuring full privacy.

Question 3

Can I watermark all pages of a PDF?

Accepted Answer

Yes. By default the watermark is applied to every page. You can also target specific pages by setting the first/last page range.

Question 4

Will the watermark be flattened into the PDF?

Accepted Answer

Yes. The watermark is rendered directly onto the page content, so it appears in any PDF viewer and is preserved when printing or sharing the file.
