Marking a document as CONFIDENTIAL, DRAFT, or with a company name protects against it being mistaken for a final version, or discourages unauthorized redistribution. Doing this consistently across every page by hand in a PDF editor is tedious.

pdfhubb's watermark tool stamps your text across every page of the document — diagonally or centered — with adjustable opacity, applied consistently in a single pass.
