Frequently asked questions
Can the watermark be removed?
It is drawn into each page's content, so it can't be hidden like a comment, but someone with a PDF editor could still delete it. It deters casual reuse rather than preventing it.
Why can't I see a watermark set behind the content?
Behind content draws the watermark first, so scanned pages and pages with a solid background cover it. Use Over content with lower opacity instead.
Can I use Chinese, Japanese, or Korean text?
Yes. Text the built-in PDF fonts can't encode is drawn as a high-resolution image, so it displays correctly.
Which image works best?
A PNG with a transparent background. Its Width is set as a share of the page width, from 5% to 100%.
Can I watermark only some pages?
Yes. Enter a range under Pages, such as 1, 3, 5-. The preview marks pages that will not be watermarked.
Is my PDF uploaded?
No. The watermark is added in your browser and the file stays on your device.
