Completely FREE signature drawer. No signup, nothing uploaded. Draw your signature with a mouse, trackpad, finger, or stylus, then download it as a transparent PNG ready to drop into a PDF, contract, or email signature — or on a white background if the destination prefers it. The drawing exists only on this page until you save it.

Getting a signature that looks like yours
Signing with a mouse feels clumsy at first. Three things help. Go bigger than feels natural — large strokes hide pointer jitter, and the export is automatically cropped to your drawing, so size costs nothing. Sign in one confident pass rather than carefully tracing; hesitation shows as wobble. And use undo liberally — the undo button removes the last stroke, so a botched flourish doesn't mean starting over. On a phone or tablet, a finger or stylus produces a far more natural line than any mouse; if the result matters, open this page on your phone.
Transparent vs. white background
The transparent PNG is the one you usually want: dropped onto a signature line in a PDF or document, only the ink shows, exactly like a real pen stroke over the printed line. The white-background version is for destinations that don't handle transparency well — some email clients and older document tools render transparent regions as black. Both exports are cropped tight to the signature with a small margin.
Using the PNG to sign documents
Most PDF readers (Preview on Mac, Acrobat, browser-based editors) let you place an image onto a page — insert the transparent PNG, scale it onto the signature line, and flatten or export. Word processors do the same with inline images, and the PNG works as a scanned-signature replacement in email signatures. Because the strokes are drawn in a blue-black or plain black ink color, the result reads as pen, not as a graphic.
A note on what an image signature is
A drawn signature image shows agreement the same way a fax signature does, and for everyday paperwork that's exactly what's expected. It is not, by itself, a cryptographic e-signature of the kind services like notarized digital-signing platforms provide — those bind identity and document integrity mathematically. For routine forms, leases, permission slips, and internal documents, an image signature is the standard practice; for high-stakes signings, follow whatever process the counterparty specifies.
Frequently asked questions
Is my signature uploaded or saved anywhere?
No. The canvas lives entirely in your browser; the site has no server that could receive it. The only copy that exists is the PNG you download to your own device, and leaving the page erases the drawing.
Why does my mouse signature look shaky?
Pointer sampling and hand mechanics — a mouse pivots from the wrist while a pen pivots from the fingers. Draw larger and faster than feels natural, pick the medium or bold stroke width, and the smoothing effect of scale hides most of the jitter. A phone screen with your finger is the easy upgrade.
Is a drawn signature legally valid?
In many jurisdictions, including under the U.S. ESIGN Act, agreements generally can't be denied validity solely because the signature is electronic, and an image placed with intent to sign commonly serves that role for everyday documents. Specific documents (wills, some notarized instruments) have stricter requirements — when the stakes are high, confirm the accepted signing method for that document type.
