PDF Watermark

About PDF Watermark

PDF Watermark is a free online tool. Stamp a text watermark such as CONFIDENTIAL or DRAFT on every page of a PDF. It runs entirely in your browser, so there is nothing to install, no account to create and no watermark added to your result.

How to use PDF Watermark

1. Upload one or more PDF or image files, depending on the tool.
2. Adjust the options such as page ranges, rotation or order.
3. Press the action button and download your finished file.

Tips for best results

• Short, uppercase text reads best; very long watermarks run off the page.
• Everything runs in your browser, so you can use PDF Watermark even on a slow connection once the page has loaded.

Limits to keep in mind

• Files are processed in your browser, so very large files depend on your device memory and may be slow. The limit is 50 MB per file.
• Password-protected PDFs may fail to open. Scanned PDFs are pictures of text, so text-extraction tools cannot read them without OCR.
