In short Seal and signature is a web tool that makes Korean-style name seals, company seals and handwritten signatures as transparent PNG images you can place on documents. It runs in your browser with no install or sign-up, and the names you type and signatures you draw stay on your device — nothing is sent to a server. Names of 1–4 characters; company seals take up to 16 characters around the edge. The first preview downloads the Serif font (about 0.6MB), and choosing Bold sans downloads about 0.3MB more. The image doesn’t replace a registered seal or an identity check.

A 24mm company seal in red and black, as transparent PNGs
In “Company seal” we chose “Round seal” and typed 주식회사가나다상사 around the edge and 대표이사인 in the center. Size 24mm, Serif font, in Seal red and Black. Both saved PNGs are 567×567px, and reopening them shows 600 dpi (24.0mm) with transparent corners. The two files inside the Save all ZIP match the ones saved one by one.
Actual result of making a seal with a made-up company name in Seal and signature v0.1.2, then reopening the saved PNGs to check their size information and transparent background. The checkerboard shows the transparent parts.

GOOD TO KNOW
Good to know
- No legal force as a registered seal or ID check. Check the recipient’s rules first, and never make or use someone else’s seal without permission.
- Only Korean (Hangul) and English letters. Names take 1–4 characters; round company seals take 16 around the edge and 6 in the center; square seals take 4–9.
- Size information (600 dpi) is in the file. During our audit, a 24mm seal inserted into Word measured 23.99mm. Choose the “Behind Text” layout in Word so it doesn’t cover the words.
- It can’t remove the background from a photo of a paper seal. It draws a new seal from text.
- The first preview downloads the Serif font (about 0.6MB); choosing Bold sans downloads about 0.3MB more.
