? Frequently Asked Questions
What types of watermarks can I add?
Add text watermarks (e.g., "CONFIDENTIAL", copyright notices) or image watermarks (logos, stamps). Customize position, rotation, opacity, size, color, and font to match your branding needs.
Can I add watermarks to specific pages only?
Yes! Apply watermarks to all pages, odd/even pages, specific page ranges (1-10), or individual pages. Perfect for watermarking content pages while leaving covers or title pages clean.
How do I make watermarks semi-transparent?
Adjust opacity/transparency (0-100%). Low opacity (10-30%) creates subtle backgrounds, high opacity (70-100%) creates prominent marks. Balance visibility with document readability.
Will watermarks affect file size?
Minimally. Text watermarks add negligible size. Image watermarks increase size based on image complexity and resolution. For minimal impact, use compressed images and lower opacity.
Can watermarks be removed by others?
Watermarks aren't security features - they can be removed with PDF editing software. For document protection, use encryption and permissions. Watermarks primarily serve as visual deterrents and ownership indicators.
