How to use the Watermark PDF tool

PDFZero adds a custom text or image watermark to every page of a PDF, with full control over opacity, rotation, position, and color, plus a live preview before you commit. Everything happens locally in your browser — no signup, no upload, no file limits.

Steps

Click the drop zone above and select your PDF.
Choose text or image watermark, then set opacity, rotation, position, and color.
Preview the watermark live on the page.
Click apply and download your watermarked PDF.

Why use this tool?

Watermarks are used to mark drafts, assert copyright, brand shared documents, or indicate confidentiality. Applying one in-browser means your document never needs to be uploaded to a third-party watermarking service.

Frequently asked questions

Can I use my own logo or image as a watermark?

Yes, you can upload an image to use as a watermark in addition to text watermarks.

Can I control how visible the watermark is?

Yes, adjust opacity, rotation, position, and color, with a live preview so you can see the result before applying it.

Will the watermark be applied to every page?

Yes, by default the watermark is applied consistently across all pages of the document.

Is my document uploaded to a server to add the watermark?

No, the entire process runs locally in your browser using WebAssembly.

Is there a limit on file size or number of pages?

No, there's no imposed file size or page limit since everything processes on your own device.
