Questions about Watermark PDF
Frequently asked technical and operational questions about watermark pdf.
Can I customize watermark text, angle, opacity, and font size?
Yes. You can enter any custom text (e.g., 'CONFIDENTIAL', 'DRAFT', or company names), adjust transparency from 10% to 100%, and set 45-degree diagonal or horizontal rotation.
Can the watermark be placed behind existing page content?
Yes. You can select either overlay (on top of page elements) or underlay (beneath text and figures) to ensure body content remains easily readable.
Where does Watermark PDF process my files?
Watermark text matrices are applied by our isolated server engine without altering original vector fonts, and files are automatically purged on a scheduled 30-minute cycle.
