What is Watermark PDF

Adding a watermark to a PDF is how you make clear a document is confidential, a draft or your property before sharing it. Text like “CONFIDENTIAL” or “DRAFT” running diagonally across every page discourages reuse without permission. Since the mark gets baked into a sensitive document, the last thing you want is to upload it to someone else’s server: that’s why fetchio.io stamps the watermark inside your browser, so the PDF never leaves your device. Type whatever text you like and the tool places it centered and diagonal across every page, with no site watermarks of its own and no daily limits.
