Remove a PDF watermark stamp, not a printed mark
Some PDFs store “Confidential” or a logo as a watermark or stamp annotation. Those can be removed, and the page underneath stays intact. If the words are burned into a scan or drawn as part of the page, they are pixels. This tool will say nothing was removed, and it will not paint over them.
Use crop PDF when the mark sits in a margin you can trim. Use compress PDF when you only need a smaller file.
