FAQ

Questions & answers

How do I add a watermark to a PDF?

Choose your PDF, type the watermark text or upload a logo, adjust its position, angle and opacity in the live preview, then click Add watermark and download.

Can I use my logo as a watermark?

Yes. Switch to Image and upload a PNG, JPG, WebP or SVG. Transparent backgrounds are kept, and you can set its size and opacity.

Can I watermark only some pages?

Yes. Choose Custom pages and type ranges such as 1-3, 5, 8-10.

Can the watermark be removed?

Watermarks are marked the standard way PDF tools recognise, like those from Word or Acrobat. That keeps your files clean and accessible, but it means a determined person with editing software can remove it. For stronger protection, also protect the PDF with a password.

Is my PDF uploaded?

No. This tool runs entirely in your browser, so the document never leaves your device — ideal for contracts, IDs and financial records.
