FAQ
Common questions
Is my PDF or image uploaded anywhere?
No. The watermark is added in your browser and nothing leaves your device.
Can the watermark be removed afterwards?
It is drawn onto the pages, so it can't be switched off like a layer. A determined person can still edit or crop it out, so a watermark discourages reuse but is not security.
Is the watermark behind or in front of the page content?
In front. It is drawn on top of the existing content with the opacity you choose, so low opacity keeps the page readable.
Which characters and image types work?
Text watermarks use the built-in Helvetica Bold font, which supports Western European characters only; use an image watermark for other scripts. Image watermarks must be PNG or JPEG.
Does it work on rotated pages and mixed page sizes?
Yes. The watermark is centered relative to each page as it is displayed, with its angle adjusted for rotated pages, and image width is a percentage of each page's width.
