About this tool

Frequently asked questions
What images can I use as a watermark?
PNG and JPEG. PNGs with transparency keep their transparency in the watermark.
Can I watermark only certain pages?
Yes — leave the page range empty to watermark every page, or enter a range like '1,3-5' to watermark just those pages.
Will the watermark print?
Yes. The watermark is baked into the page content, so it prints exactly as you see it on screen.
