Marking documents clearly
Watermarks serve two main purposes: clear marking (Draft, Confidential, Internal Use Only) and branding (a company logo lightly across every page). A good watermark is visible enough to do its job without obscuring the document's content, which is why opacity control matters more than people realize — a 30% opacity watermark reads clearly without overpowering the page.
Text watermarks are simpler and more flexible; image watermarks give you brand consistency but require a transparent PNG to look right. Diagonal full-page watermarks are the standard for confidential marking because they're impossible to crop out without cropping out content. Corner watermarks are subtler and work well for branding.
Treat watermarks as one-way. Removing a baked-in watermark is a content-aware operation that's deliberately hard to do — that's the point. Use this tool only on documents you control, and accept that the watermark is permanent.
