PDF Watermark FAQ

Quick answers about watermarking PDFs, tiling, opacity, and using logos.

How do I add a watermark to a PDF?

Upload your PDF, type your watermark text or upload a logo, then choose the opacity, colour, rotation, and whether to tile it across the page. Click 'Add Watermark & Download' and every page is stamped instantly while keeping the original content intact.

Can I stamp DRAFT or CONFIDENTIAL across every page?

Yes. Type your text (for example DRAFT, CONFIDENTIAL, or SAMPLE), set a diagonal rotation, and turn on tiling to repeat it across the whole page. Lower the opacity so the underlying text stays readable.

Can I use my company logo as the watermark?

Yes. Switch to the Logo option and upload a PNG (transparent logos look best). You can resize it, set its opacity, rotate it, and place it in a corner, the centre, or tiled across each page.

Does the watermark apply to all pages?

Yes, the watermark is applied to every page of the PDF at its correct dimensions, so it works with portrait, landscape, and mixed-orientation documents.

Will the watermark reduce my PDF quality?

No. The watermark is added as a vector overlay on top of your existing pages. The original text, images, and formatting are untouched, and the file size increase is negligible for text watermarks.

Is my PDF file secure?

Yes. Your file is uploaded over an encrypted HTTPS connection, processed on our server, and automatically deleted after processing. We never store, access, or share your documents.

Can I adjust how transparent the watermark is?

Yes. Use the opacity slider to make the watermark faint (so content stays readable) or bold (for a strong DRAFT/CONFIDENTIAL stamp). Any level from 5% to 100% is supported.
