Free signature image generator
Your name, signed beautifully — as a transparent PNG.
Type your name and choose from 8 handwriting styles, or draw your own signature with mouse, finger or stylus. Export a crisp transparent-background PNG at 2× resolution — optionally squeezed under an exact KB limit for form uploads.
Please read: SignGen makes a signature image for documents, forms and artwork. It is not a legal e-signature service like DocuSign — there is no identity verification, audit trail or certificate behind the image — and you must never use it to sign someone else's name.
Click a style to select it for export. Previews update as you type.
Draw inside the box. Strokes are stored as paths, so you can undo one stroke at a time. Changing the canvas size below keeps your drawing — it is re-rendered, not erased.
Everything happens locally in your browser: no upload, no account, no watermark. If a KB limit is set, the exporter first shrinks the PNG; if even a small PNG cannot fit, it switches to a white-background JPEG and tells you — transparency or the size cap, you choose which matters.
A signature image in ten seconds
Type your name, pick the handwriting style that feels like you, and download. The file is a transparent PNG rendered at twice the canvas size, so it stays sharp when you drop it onto a PDF, a Word document, a contract draft or an email. If you would rather sign with your own hand, switch to Draw it and use your mouse, trackpad, finger or stylus.
Forms that ask you to "upload your signature" — exam applications, HR portals, bank KYC pages — usually want a small image on a plain background with a strict size limit. That is why the exporter has a KB cap: set, say, 50 KB and it will hit that budget or tell you plainly what it had to do to get there. The exam signature guide lists the limits common portals ask for.
How the styles work
Each style is a real open-source handwriting typeface (see the eight below), rendered by your browser — not a filter over a photo and not a traced copy of anyone's handwriting. The slant control leans the writing the way a fast hand naturally leans, and the flourish adds the under-sweep many people finish a signature with. Because the starting point is a font, the result is a designed signature: consistent every time, which is exactly what you want when you adopt one style and use it everywhere.
What this is — and is not
SignGen produces a picture of a signature. Many everyday workflows accept exactly that: an image pasted into a document, an uploaded specimen on a form, artwork signed in the corner. What it does not produce is a cryptographic or legally certified electronic signature: there is no signer identity check, no document hash and no audit trail. Where a law or a counterparty requires a qualified e-signature, use a dedicated e-signature service. And never generate or use a signature in anyone else's name — that is forgery, whatever tool made the picture.
Frequently asked questions
Is the downloaded signature really transparent?
Yes. The PNG is rendered on an empty canvas, so every pixel that is not ink has an alpha value of 0. Place it over coloured paper or a scanned page and the background shows through. The checkerboard you see in previews and on the drawing pad is only there to make the transparency visible — it is not in the file. Only the last-resort JPEG fallback (used when a KB cap is impossibly small) has a white background, and the exporter says so when it happens.
How do I keep the file under my form's KB limit?
Enter the limit in "Max file size" before downloading. The exporter first tries the full-size PNG, then progressively smaller PNGs, and reports the final size and dimensions. Signature images are mostly empty space, so even 20–50 KB is usually reached without visible quality loss. If a portal also specifies exact pixel dimensions, set them in the width and height boxes.
Can I use a generated signature on a contract?
That depends on the contract, the jurisdiction and the other party's requirements — an image of a signature is accepted in many everyday contexts, but some agreements require a certified e-signature or a wet-ink original. SignGen cannot tell you which applies; check the document's instructions, and for anything high-stakes use a proper e-signature service or sign on paper.
Why do the styles look like fonts, not like my handwriting?
Because they are fonts — eight open-source handwriting typefaces, listed with their licences on the About page. A font gives you a repeatable, tidy signature. For your actual hand, use Draw mode: it captures your own strokes and exports them the same way.
Do you store my name or my signature?
No. The generator runs entirely in your browser; there is no server component to upload to. See the Privacy page for the details.
