Can I make my own stamp?

Yes — type any text (up to 28 characters), pick any colour, and add the date and a name underneath.

Can I stamp every page?

Yes — choose “Every page”. Each page gets its own stamp in the same place, and you can still move any of them.

Is the stamp a picture?

No — it's real text and lines, so it stays sharp when printed and you can change the words in the editor.

Is my PDF kept private?

Yes. Your file travels over an encrypted connection and stays private to you — nobody else can open it. Projects you save are kept in your account until you delete them, and download links we email you expire after 7 days.

Stamp a PDF

Mark invoices as paid, contracts as approved and drafts as drafts — the way a rubber stamp would. Pick a ready-made stamp or type your own, choose its colour, style (rubber double line, box or round), size and tilt, add today's date and your name, and put it on the first page, the last page or every page. The PDF opens in the Mega AI Studio with the stamp in place and selected, so you can drag it, resize it or change its text before you download.
