Add Watermark to PDF Online

Add a Text or Image Watermark to a PDF

Stamp a custom text watermark (such as "CONFIDENTIAL", "DRAFT", or your company name) across every page of your PDF. Useful for marking documents before distribution or adding branding.

How it works

1. Upload your PDF.
2. Enter the watermark text, choose position, opacity, and font size.
3. Download the watermarked PDF.

Tips for best results

• Use a low opacity (20-40%) for diagonal watermarks so the document text remains easy to read.
• For official documents, position the watermark diagonally across the centre of each page.
• Watermarks added here are embedded in the PDF content and cannot be easily removed by standard PDF viewers.

Frequently asked questions

Can I remove the watermark later?

Watermarks added here are baked into the page content. They cannot be removed with a standard PDF viewer.

Can I watermark a password-protected PDF?

No - remove the password protection first, then add the watermark.

Is text or image watermarking supported?

Currently text watermarks are supported. Image watermarks are coming soon.
