FAQ: Common Questions
Q: How to add watermark to PDF?
Use DevToolbox PDF Watermark: upload PDF → enter watermark text (e.g., "CONFIDENTIAL") → adjust position, opacity, and angle → download. You can also use Adobe Acrobat → Edit PDF → Watermark → Add.
Q: Can PDF watermark be removed?
It depends on the type: visible text watermarks can be removed with professional tools (e.g., Adobe Acrobat Pro); image watermarks are harder but still removable; invisible digital watermarks are nearly invisible and hard to remove — they are used for copyright tracking.
Q: Does watermark affect PDF printing?
Yes. Watermarks will appear on printed pages. If you want a watermark that only shows on screen but not in print, you need Adobe Acrobat's "Screen Watermark" feature — ordinary tools cannot do this.
