The free Watermark and Page Numbers tool lets you stamp your PDFs with a text watermark and optional page numbers, all in your browser. Upload your PDF, enter the watermark text (for example CONFIDENTIAL, DRAFT, or your name), and set the opacity. The tool places the watermark on every page so that recipients know the origin or status of the document. You can also enable page numbers so each page shows a number at the bottom. Useful for content creators, freelancers, and companies who share drafts or final files and want to protect ownership or clarify pagination.

Processing uses pdf-lib: the PDF is loaded in memory, each page is modified with the watermark and optional numbering, and a new file is generated for download. No file is uploaded to a server; everything runs on your device. The result is a single PDF with your watermark and page numbers applied. You can use different opacity levels to make the watermark subtle or prominent.

Watermarking helps protect intellectual property and brand your documents. Adding page numbers makes long PDFs easier to reference in meetings or print. This tool is free, requires no sign-up, and keeps your files private. Use it for proposals, contracts, reports, or any PDF you share with others.
