Protect and Brand Your Work
Watermarking is a powerful way to claim ownership and restrict unauthorized use of your school materials, draft reports, exam sheets, and portfolios. Our editor supports both **Text watermarks** (like "DRAFT", "CONFIDENTIAL", "SAMPLE") and **Image watermarks** (like your school logo or crest).
- Text & Image Support: Stamp custom text labels or high-res JPG/PNG images.
- Granular Control: Tweak the opacity, rotation angle, and scale values to your liking.
- 9 Alignment Options: Align in the center, or snap to corners and edges instantly.
