About PDF Watermark
PDF Watermark stamps your text — CONFIDENTIAL, DRAFT, SAMPLE, a company name — diagonally across the centre of every page in large, light-grey letters. It is the usual way to mark drafts and discourage casual copying of documents you share.
The text size adapts to each page, Gujarati and Hindi text are supported, and the page content remains readable underneath. Files are sent over HTTPS, processed on our server and deleted automatically after you download the result.
