Common questions
Does this tool send my PDF anywhere?
No. Watermarking runs entirely in your browser. Your PDF and the watermark you add never leave your device.
Can I add a different watermark to each page?
Currently this tool applies the same watermark to every page. To watermark only specific pages, split the PDF first using Split PDF, watermark the relevant section, then merge with Merge PDF.
Can I add an image as a watermark?
This tool supports text watermarks only. For image watermarks, use a desktop PDF editor or convert your image to a transparent overlay first.
Will the watermark appear on top of or behind text?
Watermarks are drawn on top of existing content with the opacity you choose. A 30 to 40 percent opacity keeps original content readable while still showing the mark clearly.
Is the watermark removable from the output?
A determined editor with PDF tools can usually remove or obscure visible watermarks. Use watermarks to discourage casual misuse, not as a security measure for highly sensitive content.
Why is the live preview slightly different from the final PDF?
The preview shows approximate placement using browser rendering. The downloaded PDF uses precise coordinates from pdf-lib and may look marginally different in scale or positioning.
