Can I stamp multiple pages and multiple spots?

Yes. Move between pages in the page list and place stamps or signatures freely on each one.

What kind of stamp image should I upload?

A transparent-background PNG works best (JPG is fine too). A transparent PNG made with the background remover comes out cleanest.

No. Reading the PDF and merging the stamp both happen in your browser — the file is never sent or stored.

Place a stamp or signature image onto a contract PDF, drop it exactly where you want, and save. No printing or scanning needed.

Got a contract as a PDF? Stamp it directly — no printing, stamping, and re-scanning.
Drag your stamp or signature anywhere on any page and resize it to fit. Multiple pages and spots are fine.
The whole thing runs in your browser, so the contract never leaves your device — safe for sensitive documents.
