Stamp Maker
Generates a Korean name stamp — round or square, seal-script or plain — as a red-ink transparent PNG.
A round or square 도장 image with a name in it, as a transparent PNG in cinnabar red — for the documents that ask for a stamp and accept an image. It is a picture of a stamp and nothing more: it is not a registered 인감 and carries no legal weight of its own.
The chequerboard is transparency.
Name
One to six characters. Two sit side by side; three or four are laid out 2×2.

How to use it
Type the name
One to six characters. Two sit side by side, three or four are laid out 2×2 — the arrangement a carved seal uses.
Choose round or square
Round is the seal shape; square reads as a 막도장. The border thickness is adjustable because a thin ring looks modern and a thick one looks carved.
Add some wear
At 0% it is a clean vector, which looks like clip art. Raising it leaves the gaps of an under-inked press, and the texture can be re-rolled until one looks right.
Common questions
Can I use this instead of a real 인감?
No. An 인감 is a seal registered with a 주민센터 and proved by a 인감증명서; an image cannot be either. This is for the many documents that simply want a stamp on them.
Why is my name cut off?
Past six characters there is no arrangement that stays legible inside a stamp. Use a shorter form — a seal traditionally carries a name, not a title.
How do I put it on a PDF?
Save it to the stamp shelf and PDF Fill & Sign will offer it, or download the PNG and place it wherever you like. It is transparent, so it sits over existing text.
