Download the updated PDF when the watermark looks right.

Common use cases

This tool fits draft reviews, sample documents, confidential files, internal copies, or handouts that need a strong visible label over the page content.

Watermark vs. header or page numbers

Use this tool when the label should sit across the page content area. If you need small repeated notes near the page edge, use the header and footer tool. If you need numbering that changes on every page, use the page-number tool.

Limits

This version adds text watermarks only. It does not OCR text, merge multiple PDFs, or edit original page content in place.

Concrete examples

Mark a review copy as Draft, stamp a proposal as Sample, apply Confidential across an internal PDF, or add Internal Use Only before sharing a working version.

Common mistakes and what to do

If the watermark is too hard to read, raise the opacity or size. If it blocks too much content, lower the opacity or switch from repeated to centered layout. If you only need a small label at the top or bottom edge, use the header and footer tool instead.

Privacy and processing

This tool processes PDFs in your browser. The PDF you select is not uploaded to PDFresh for this workflow. Processing speed and stability still depend on your device and browser.
