How is this different from a watermark?

A watermark is repeating, semi-transparent text across the whole page. A stamp is a single image at a specific spot. Different jobs, which is why they are separate tools.

Can the stamp be removed by the recipient?

No, it is composited into the page content rather than added as an annotation, so removing it would mean editing the page graphics.

What resolution should the image be?

At least 300 DPI at its final printed size, so roughly 600 pixels across for a 50 mm stamp. A low-resolution logo is very visible next to crisp vector text.

About Add Stamps

Places an image stamp on chosen pages at a position and size you set — a logo, an approval mark, a company seal. Transparent PNGs composite cleanly over existing content.

Both the document and the stamp image are handled locally — a company seal or signature mark is never uploaded.

How to use Add Stamps

Load the PDF and upload the stamp image — a transparent PNG gives the cleanest result.
Position it on the page and set the size using the handles.
Choose which pages receive it — every page, a range, or just the first.
Apply and download.

On a production

An approval mark on a schedule, a company logo on a document assembled from a plain template, a QR code linking a printed page back to the live version. All of them are an image that has to sit in a precise spot on specific pages.
