About Watermark PDF
Marking a PDF as DRAFT, CONFIDENTIAL, or with your company name takes seconds with Berlvis Watermark PDF. Type your text, set the opacity and rotation, and we stamp every page using the embedded Helvetica Bold font. The original document is never uploaded, which matters when you are distributing pre-publication contracts or financial drafts.
