Frequently Asked Questions

For most documents, 30-40% opacity provides good visibility without interfering with readability. Use 10-20% for subtle protection, 50-60% for clear marking, and 70%+ for high-security documents where visibility is paramount.

No! Watermarks are added as overlays without modifying the original content. Text remains searchable and selectable, and the underlying document quality is preserved. Only the visual appearance includes the watermark overlay.

Watermarks provide visible deterrence rather than security through obscurity. While determined individuals with advanced tools might attempt removal, watermarks serve as clear ownership marking and legal evidence of document authenticity.
