Add Watermark to PDF
HugPDF adds text watermarks to PDF files locally in the browser. Files are never uploaded to a server for watermarking; your chosen text is placed on every page with adjustable size, color, angle and opacity. This tool accepts text rather than logo images, and a watermark does not prevent copying.

Mark PDF drafts and review copies with your own text
Enter a short label such as DRAFT, CONFIDENTIAL or your organization name. The same text is added to every page. Set the color, size, angle and opacity before processing, then download a separate watermarked copy.
This tool creates text watermarks, including Arabic and English. It does not accept a logo image or let you select a page range. For an image logo on a selected page, use Edit PDF. For sequential page labels, use Add Page Numbers.
A visible watermark labels a document; it does not encrypt it, restrict copying or permanently hide the content beneath it. Use password protection when a password is needed to open the file. Keep the original and inspect the downloaded copy before sharing.
Start with a short label and moderate opacity. Check both portrait and landscape pages, and make sure the watermark does not obscure small print, signatures or QR codes. Long text may appear smaller to fit the page.
What this tool does
Watermark text is drawn as an image, which supports Arabic and English without font-encoding errors. Set color, size, angle and opacity.

FAQ
Frequently asked questions
Does Arabic text work?
Yes. Watermark rendering supports Arabic and mixed text.
Can I watermark only selected pages?
This tool applies the same text watermark to every page of the selected PDF. It does not offer a page-range control.
Can I use a logo as the watermark?
This tool accepts text only. Use Edit PDF to place an image logo on a selected page.
Does a watermark stop people from copying the PDF?
No. A visible watermark does not encrypt the file or prevent copying. It also does not securely remove information covered by the watermark.
