Sign in the box below with a mouse, finger or stylus. Slow strokes come out thicker, fast ones thinner. Using only a keyboard? Choose "Type" above.
A transparent PNG lets you place just the signature on a document or image. White suits places that do not support transparency.
SVG is a vector file that stays sharp at any size (drawn signatures only).
Empty margins are trimmed and the file is saved at 3× the on-screen size. The signature is made in your browser only and is never stored or sent anywhere.
A signature image is a picture with no identity check (such as a certificate) attached. Before using it on a contract or an official form, check that the other party or office accepts image signatures.
What it is
A tool for making a signature image to put on documents. Draw in the signature box with a mouse, finger or stylus, or type your name and get it in a handwriting-style font. The finished signature is trimmed to its ink and saved as a transparent PNG, ready to drop onto a signature line in a Word document or PDF. A drawn signature can also be saved as SVG, which stays sharp at any size.
How to use
- Under How to make it, choose Draw or Type.
- To draw, sign in the box. Use Undo stroke for a wrong stroke or Clear to start over.
- To type, enter your name and pick a font: handwriting, brush or serif. You can slant it slightly to the right.
- Choose a Pen color (black, navy, blue or custom) and the Thickness. Changes apply to strokes already drawn.
- Pick a transparent or white Background and click Save PNG (or Save SVG).
How it works
- Drawing engine: the MIT-licensed signature_pad library, which draws Bézier curves whose width follows the stroke speed.
- Thickness: the slider value (1–8) sets the thinnest line to 0.4 times and the thickest to 1.25 times that value in pixels.
- Resolution: the signature is redrawn at 3× the on-screen size, trimmed to the ink, and given a margin of 6% of the longer side (at least 4 px).
- Fonts: East Sea Dokdo (handwriting), a subset of Nanum Brush Script (brush) and Noto Serif KR (serif), served from this site under the SIL Open Font License. Characters a font lacks use your device font. The fonts cover Latin and Korean letters.
- SVG: drawn signatures only, with the viewBox cropped to the trimmed area.
Examples
| Method | Setting | Result |
|---|---|---|
| Draw | black, thickness 2.5, transparent | signature.png, margins trimmed |
| Draw | navy, white background | signature.svg with a white rectangle behind |
| Type “Jane Doe” | brush, blue | signature-Jane-Doe.png |
For a company seal or personal stamp image use the stamp maker; to clean up a scanned paper stamp use the stamp background remover (both Korean pages).
FAQ
Can I use the signature on a contract?
A signature image is a picture with no identity check (such as a certificate) attached. It works where image signatures are accepted, such as internal documents or quotes; for contracts and official forms, check first that the other party or office accepts one.
Is the background transparent?
Yes, a transparent PNG is the default, so the signature sits on top of a signature line in Word, Google Docs or a PDF editor without a white box. Switch the background to white for places that do not support transparency.
Does it work on a phone?
Yes. Sign in the box with a finger or stylus; the page does not scroll while you draw. Slow strokes come out thicker and fast ones thinner, much like a real pen.
Can I make one with only a keyboard?
Choose Type, enter your name and pick a handwriting, brush or serif font. Every setting and the save buttons work with the keyboard.
Is my signature stored anywhere?
No. It exists only in your browser and is not even a file until you click save. Nothing is sent to a server or written to browser storage.
