Protecting a document with a watermark is one of the quickest ways to signal its status — whether it's
confidential, a draft, or simply branded with your name. PDFix lets you add a custom text watermark
to every page of any PDF, completely free, right in your browser.
No desktop software, no account, and no PDFix branding added to your output.
Adjust the text, opacity, font size, and angle before applying. A live preview shows you exactly
how the watermark will look before you commit. Once applied, download your stamped PDF instantly.
After watermarking, you can compress the PDF to reduce its size,
or merge it with other documents into a single file.
