You've spent hours putting together a proposal. Now you need to send it to a client for review — but you don't want them forwarding it to your competitors. Or maybe you're sharing a draft internally, and you need everyone to know it's not final yet.
Why watermarks matter
- Protect intellectual property: "CONFIDENTIAL" makes sharing harder.
- Mark document versions: "DRAFT" tells readers this isn't final.
- Claim ownership: Your company name on every page.
- Deter misuse: A visible watermark discourages unauthorized copying.

- Choose the position, font size, and opacity.
- Click process and download your watermarked PDF.
Choosing the right watermark style
- Opacity matters. Around 20-40% is visible without being distracting.
- Positioning. Diagonal across the middle is harder to crop out.
- Font size. Too small and it's ignored; too large and it obscures content.
- Color. Use a neutral color like gray or dark red.
