About Stamp Maker

A stamp is a small piece of design with strict rules: the ring text has to sit evenly around the curve, the middle has to stay readable, and the whole thing has to hold up when it is shrunk to the corner of an invoice. This maker handles the geometry for you — type the wording and the curved text is spaced along the ring automatically, at whatever size and letter spacing you choose.

Start from a preset if you want a head start. 'Company seal' gives the classic two-ring circle with the organisation name curving over the top and the city underneath; 'APPROVED', 'PAID' and 'CONFIDENTIAL' give the boxed office marks; 'Date stamp' drops today's date into the middle of a ring; 'Notary / official' is the wider oval used for registrar and government seals. Every preset is only a starting point — change any field afterwards.

The distress slider is what separates a flat graphic from something that looks stamped. It punches small gaps and scrapes through the ink the way a real rubber stamp does when it is pressed unevenly. Keep it low for a crisp digital seal, push it higher for an authentic pressed look. The pattern is fixed rather than random, so what you see in the preview is exactly what downloads.

Download a transparent PNG and the stamp will sit over a scan, an invoice or a photo with nothing but the ink showing. Pick a larger export size for print — the stamp is redrawn at that resolution rather than scaled up, so the curves and the border stay clean.

Frequently asked questions

What shapes can I make?
Circle, oval, rectangle and square. Circle and oval carry curved text around the ring with up to three straight lines in the middle; rectangle and square stack every line you type inside a box border.
Is the downloaded stamp transparent?
Yes. Leave 'Transparent background' ticked and download the PNG — the area around and inside the stamp stays clear, so you can drop it straight onto a document, invoice or photo. The JPG option always comes with a white background, because JPG cannot store transparency.
What size should I download?
1000 × 1000 px suits most on-screen and A4 use. Pick 2000 or 3000 px if the stamp will be printed large or placed on a high-resolution scan — it is drawn fresh at that size, not scaled up, so it stays sharp.
Can I put the stamp on a PDF or a photo?
Yes — download the transparent PNG, then use the watermark tool to place it over an image, or add it as an image in your PDF editor. Because the background is clear, only the ink shows.
Is this a legally valid seal?
No. This is a design tool that produces an image. Whether a seal carries legal weight depends entirely on your jurisdiction and on who is entitled to use it — only create stamps for an organisation you are authorised to represent.
Is it free?
Yes, unlimited and free, with no sign-up and no watermark on what you download.
