Pro tips
- Use 30–50% opacity so watermarks read without hiding content
- Diagonal 45° watermarks are hardest to remove visually
- Transparent PNG logos look cleaner than JPG
- Everything runs in your browser — nothing is uploaded, so it's safe for confidential, financial, and legal PDFs.
Best practices
- Watermark AFTER final edits, never before
- Keep an un-watermarked master copy
Common mistakes to avoid
- 100% opacity — hides the underlying text
- Tiny watermarks that don't survive screenshots
