How and when to add a watermark to a PDF
A watermark is a semi-transparent text overlaid on a document's content, usually diagonal and repeated across the page. It signals a document's status (draft, confidential, copy) or discourages unauthorized use of your content before the final version is ready to share.
It's especially useful when sharing a contract or proposal still subject to change, when sending a document for external review and you want to make clear it isn't final, or when distributing material you want identified as yours at a glance.
With DocuMixa you choose the exact text and visual intensity: subtle so it doesn't interfere with reading, medium for general use, or strong when you want it impossible to miss. The watermark applies to every page of the document in one step.
Keep in mind a text watermark is a visual signal, not legal or cryptographic protection: anyone with advanced PDF editing tools could attempt to remove it. For genuinely sensitive content, combine it with other measures like access control on the file.
