Frequently Asked Questions

How does the watermark eraser work?

It strips out the underlying text and image objects that overlap with the red boxes you draw on the preview canvas.

Can I apply the watermark to specific pages only?

Yes, you can use the 'Page Range' setting to apply the watermark exclusively to certain pages (e.g., '1, 3-5').

Will removing a watermark ruin the text underneath?

Our tool attempts to surgically remove vector and text paths inside your drawn box. In some complex PDFs, it may remove the text directly beneath the watermark as well.
