Watermark PDF

How it works

Upload a PDF and choose a text or image watermark, or page numbers. For watermarks, control position (a 9-point grid or tiled mosaic), rotation, opacity, color, bold/italic, whether it sits above or below your content, and which pages it applies to. Download the result immediately — both the original and the output are deleted from our servers automatically after one hour.

FAQ

Can I use my own logo as a watermark?

Yes — switch to Image mode and upload a PNG or JPG. It's placed with the same position, rotation, and opacity controls as text.

What does 'mosaic' do?

It repeats the watermark in a 3×3 grid across the page instead of a single stamp — common for documents that need coverage even if part of a page is cropped or covered.

Can I apply a watermark to only some pages?

Yes — enter a page range like '1-3, 5'. Leave it blank to watermark every page.

What does 'layer' control?

Whether the watermark sits above your content (on top, most common) or below it (useful for a background stamp that existing text should remain readable over).

Can I add both a watermark and page numbers?

Run the tool twice — once for the watermark, then again on the result for page numbers.

Can I watermark a password-protected PDF?

Not directly — unlock the file first with our Unlock PDF tool, then watermark it.
