Frequently asked questions
- Are my files uploaded to a server?
- No. The watermark is applied locally in your browser and the protected PDF is generated on your device.
- What can I customize in the watermark?
- You can set the watermark text and fine-tune the font size, opacity, rotation, and color until it looks right on your pages.
- Is the watermark applied to every page?
- Yes. The watermark is stamped on all pages of the PDF so the whole document is protected uniformly.
- Can the watermark be removed later?
- No. The watermark is baked into the page content itself, not added as a removable overlay, which makes it an effective deterrent.
- Do I need an account to add a watermark?
- No. The tool is free and requires no registration, and your file never leaves your browser.
