Can I add an image as a watermark?

Yes! Switch to "Image Watermark" mode and upload a PNG or JPG logo. It will be centered on every page.

How do I make the watermark semi-transparent?

Use the Opacity slider. 30% is typical for document watermarks, 10-20% for subtle branding.

Can I tile the watermark across the entire page?

Yes. Set Position to "Tile (repeat)" to stamp the watermark in a repeating grid pattern.

Is my PDF sent to a server?

No. Watermarking runs entirely in your browser using pdf-lib. Your files stay private.

What text styles can I use?

Text watermarks use Helvetica Bold. You can control size (12–120px), color, opacity, and rotation angle.
