Frequently Asked Questions
- Can I use my company logo as a watermark?
- Yes. You can upload an image file like a PNG or JPG logo and use it as a watermark. Adjust its size and opacity to fit your document.
- Does the watermark work with scanned PDFs?
- Yes. Watermarks are added as an overlay on top of the existing content, so they work with any type of PDF including scanned documents.
