What the Watermark PDF tool does
The tool lets you use either text or an image, adjust placement visually, and export the final watermarked PDF. It works well for proposals, contracts, internal files, and any document that needs branding or a clear visual marker.
Because the workflow runs locally, ZeroPDF is a stronger fit for commercial documents, contracts, proposals, proofs of authorship, and internal materials where privacy matters.
