Frequently asked questions
Can I change the watermark color?
The current version uses a fixed red tone for visibility; custom colors are on our roadmap.
Does the watermark appear on every page?
Yes, it's applied diagonally across every page of the document.
Is this reversible?
No — the watermark is baked into the PDF content, so keep your original file if you need an unwatermarked copy.
