Vellum finds the watermarks laid over a PDF document — stamp annotations, marked artifacts, layers named “Draft” or “Watermark”, drawing blocks repeated identically on almost every page — then excises them from the content stream, without rasterising or recompressing the rest of the document. Every detected item is listed with the text it displays and the pages it affects: you tick what should go, and a before / after preview confirms the result before download. The limit is stated plainly rather than hidden: a watermark merged into the page image, as on any scanned document, is no longer a separable element and this tool will not remove it. Analysis and removal are computed by your browser, with no upload to a server, and the tool is meant for documents you hold the rights to.
It removes watermarks laid over the document — stamp annotations, layers named “Draft” or “Watermark”, drawing blocks repeated identically on almost every page — by excising them from the content stream without touching the rest. A watermark merged into the page image of a scanned document, though, is no longer a separable element: this tool won’t remove it.
Only if you hold the rights to the document. Removing an ownership mark, a third party’s stamp or a licensing watermark without authorization can amount to a copyright or contract violation, regardless of whether it’s technically possible.
No, detection and removal are computed locally in your browser, with no upload of the PDF, and the tool is free to use.
