Frequently asked questions
Can I use my logo as a watermark?
Yes: upload a PNG (ideally with a transparent background) or JPG and adjust its size and opacity.
How do I get the classic diagonal "CONFIDENTIAL"?
Choose a text watermark, Center position and 45° rotation; tune the opacity to taste (30–40% usually looks right).
Can the watermark be removed later?
It's stamped into the page content, as if printed: it's not a layer that can be toggled off in a viewer.
Can I apply it to only some pages?
For now it applies to the whole document; if you need only some pages, split the PDF first and merge afterwards.
Is my document uploaded anywhere?
No, the whole process is local to your browser.
