Why use Morfily Watermark PDF?

A watermark such as "CONFIDENTIAL", "DRAFT" or your company logo shows who a document belongs to and discourages copying.

A low opacity keeps the original content easy to read.

Frequently asked questions

Which opacity should I use?

Between 15% and 30% is visible but still lets readers see the text underneath.

Can I use my logo?

Yes. Choose "Image / logo". A PNG with a transparent background looks best.

Can a watermark be removed?

Watermarks added this way are part of the page, which makes them hard to remove, but no watermark is impossible to edit.

Is my file uploaded?

No. The watermark is added in your browser.
