Can the watermark be removed after adding it?

The watermark is permanently embedded in the file. It cannot be easily removed, which is the purpose of using it — content protection.

Does watermark affect file size?

Text watermark impact on size is minimal (kilobytes). Image-based watermarks may increase size slightly depending on image resolution.

Can I put different watermarks on different pages?

Currently the same watermark applies to all selected pages. For different watermarks, apply to separate page groups.

Does watermark appear when printing?

Yes, the watermark is a permanent part of the file and appears when printing and on screen with the same appearance.

What is the best logo image format?

PNG with transparent background is best — allows page content to show behind the logo. JPG also works but with a white background.

Tips & Best Practices

💡For confidential docs: use 30-50% transparency with 45-degree diagonal angle — covers page without blocking reading.
💡For company logo: place in corner with 10-20% transparency — looks professional without distraction.
💡"Draft" watermark is important to prevent drafts from being considered final copies.
💡For extra protection: use watermark with Protect PDF tool together — visual + technical protection.
💡Ensure watermark doesn't hide important info — test on different pages before applying.
