Electronic Seal Maker
Make a seal image in four layouts: round company seal, oval invoice seal, square personal seal and rectangular statement stamp. Type the organisation name and the seal title and the preview updates live — the round seal uses the real double-ring plus five-pointed star arrangement with characters rotated along the top arc, and the square seal lays out two to four characters in the traditional top-right, bottom-right, top-left, bottom-left order. Typography is fully adjustable: type size (55–145%), letter spacing (tighter to wider) and margin (pushes the text in from the border) are three independent controls — changing one does not quietly change another. Tune ink colour, diameter (30–50mm) and typeface too; on the round seal the outer and inner rings are controlled separately and the inner ring can be switched off for the very common single-ring contract stamp, with each ring's weight set independently — thickening the inner ring grows it inward so it never crowds the text. Add wear, tilt and opacity so it looks stamped rather than pasted. Export a 300 DPI transparent PNG for Word, PDF or a mock-up. Everything is drawn in your browser and nothing is uploaded. The output is an image, not a legally binding e-signature — use it for mock-ups and layout previews only.
Wraps to fit the frame, up to three lines, with the type shrinking as needed.
Wear and tilt mimic a hand-stamped impression; the exported PNG stays crisp.

How to use
- Pick a layout: round company seal, oval invoice seal, square personal seal or rectangular stamp
- Type the text — the organisation name curves along the top arc, the square seal takes two to four characters, the bar stamp wraps to fit
- Set the type: type size scales the glyphs, name spacing opens or tightens the gaps along the top arc, and margin pushes the whole line in from the border — the three do not interfere (margin never shrinks the type, spacing never changes its size, and spacing only affects the organisation name, not the seal title underneath)
- Adjust style and texture: ink colour and diameter; on the round seal you can hide the inner ring, and each ring's weight is set separately
- Hit Download PNG for a 300 DPI transparent image, or Copy image to paste it straight into a chat
