Frequently Asked Questions

How do I add a watermark to a PDF?

Choose a PDF, type your watermark text, pick a layout, color and opacity, and click Add Watermark. The watermarked PDF downloads right away.

What opacity should a watermark use?

Around 20–30% keeps the document readable while making the watermark clearly visible. Use higher opacity for proofs you do not want reused.

Can I watermark only certain pages?

Yes. Enter a page range such as 1-5 in the Pages field; leave it empty to watermark every page.

Can watermarks be removed?

Text watermarks deter casual copying but can be removed with a PDF editor. For strong protection, combine them with restricted sharing.

Why can I only use Latin characters?

The watermark uses a standard PDF font that is available in every viewer without embedding, and those fonts only cover Latin characters.
