Frequently asked questions
Everything you need to know about the Watermark PDF.
Can the watermark be removed later?
The text is drawn into each page's content, so it can't be switched off like a comment. Keep your original file if you need an unmarked copy.
What opacity should I use?
Around 15–25% keeps the document readable while making the watermark clearly visible. Use a higher value for a stronger mark.
Does it work with scanned PDFs?
Yes. The watermark is drawn on top of each page, whether the page contains text or a scanned image.
Is my document uploaded?
No. Everything happens locally in your browser, which makes it safe for confidential files.
