Frequently asked questions

Can I use my own logo?

Yes. Switch to the Image option and upload a PNG for transparency or a JPG. Adjust the size so it sits how you want.

How do I make the watermark subtle?

Lower the opacity to around 20–30% and choose a light gray color so text underneath stays readable.

Can I watermark only some pages?

This tool applies the watermark to every page. Split out the pages you need first if you want a partial watermark.
