Protect and label your documents by stamping a diagonal text watermark across every page. Type any text - 'Confidential', 'Draft', a name or a URL - and adjust the size and opacity to taste. It is ideal for marking drafts, deterring copying, or branding handouts. The watermark is drawn with pdf-lib in your browser, so your PDF is never uploaded.
