01
Draw
Use a mouse, trackpad, stylus, or finger. The canvas captures pressure on touch devices for natural variation.
02
Style
Pick an ink color, choose fountain, ballpoint, or brush pen, and dial in the weight to match your document style.
03
Export
Copy to clipboard or download a transparent PNG. Drop it directly into Gmail, Outlook, PDFs, or Canva.

Answer-first
How do you create a handwritten signature image online?
Draw your signature with a mouse, trackpad, stylus or finger, then export it as a PNG with a transparent background so it sits on a document or email without a white box around it. Three pen styles change how the stroke behaves — a fountain nib with smooth even lines, a ballpoint with a consistent thin line, and a brush whose width follows stylus pressure — and eight ink colours cover the usual navy, black and blue-pen looks. Everything happens on a canvas in your browser: the drawing is never uploaded, there is no watermark, and no account is needed to export.
- Output
- PNG with a transparent background, no watermark
- Pen styles
- 3 — fountain (smooth), ballpoint (thin, even), brush (width follows stylus pressure)
- Ink colours
- 8 — midnight, navy, cobalt, teal, forest, burgundy, graphite, slate
- Input
- Mouse, trackpad, touchscreen or stylus
- Where it runs
- On a canvas in your browser — the drawing never leaves the device
- Cost
- Free, no account required; signing in only adds saved signatures across devices
How to make a signature image you can reuse
- 01
Pick a pen and ink
Choose the stroke style first — brush varies its width with stylus pressure, ballpoint stays thin and even, fountain sits between them. Then pick an ink colour that reads as pen rather than print.
- 02
Sign the canvas
Draw in one continuous motion if you can; stop-start strokes look traced. A stylus or finger on a touchscreen gives a far more natural line than a mouse. Clear and redo until one feels like yours.
- 03
Add the sign-off lines
Optional closing, name, role and company can sit under the drawn line, so the exported image works as a complete email or proposal sign-off rather than a bare squiggle.
- 04
Export the transparent PNG
Download it once and reuse it: drop it into a PDF, a proposal template, a slide deck or an email signature. Because the background is transparent it keeps working on white, cream or coloured pages.
Right tool if…
- A reusable signature image for proposals, invoices, letters and email sign-offs
- Anyone without a scanner who needs something better than a photo of paper
- Placing a signature into a PDF that has no signature field of its own
Reach for something else if…
- Proving who signed a document — an image can be copied by anyone who receives it, so use a signing flow that records identity, time and an audit trail
- Documents that require a witnessed or notarised wet signature, such as many deeds and wills
- Reproducing somebody else’s signature, which is forgery regardless of the tool used
Common mistakes
Signing too small
A signature drawn tiny and then enlarged to fit a signature line looks soft and pixelated. Draw large on the canvas and scale down when you place it.
Emailing the raw image around
Every copy of the file is a usable copy of your signature. Keep it where you keep other credentials, and prefer a proper signing flow when the other side needs proof rather than appearance.
Assuming an image alone makes a contract binding
In most cases the signature is only one part of the evidence. What makes an electronic signature defensible is the record around it — who signed, when, from where, and against which version of the document.
Questions people ask
Is the signature generator free?
Yes. Drawing and exporting the transparent PNG are free, with no watermark and no account. Signing in adds saved signatures that follow you into the BrieflyGo editor and across devices.
Does the exported PNG have a transparent background?
Yes. The export is a PNG with real transparency, so the stroke sits directly on whatever is behind it — white paper, a cream letterhead or a coloured slide — with no white box.
Can I draw with a finger or stylus?
Yes, and it is worth doing — a stylus or finger produces a far more natural line than a mouse.
Does pressure sensitivity work?
On devices that report pointer pressure, such as an iPad with an Apple Pencil or a Surface with its pen, the brush style varies stroke width with how hard you press. Ordinary touch and mouse input report no pressure, so the stroke falls back to a consistent mid-weight line.
Is my signature uploaded to a server?
No. The canvas and the PNG export both happen in your browser. The image only leaves your device if you deliberately save it to your BrieflyGo account or send it somewhere yourself.
Is a drawn signature legally valid?
A drawn image can form part of a valid electronic signature in many jurisdictions, but on its own it proves very little — anyone holding the file can paste it anywhere. What makes electronic signing defensible is the surrounding record: signer identity, timestamp, and which version of the document was signed. For anything that matters, use a signing flow that captures that, and ask a lawyer about your specific document.
How do I put the signature into a PDF?
Open the PDF in the BrieflyGo editor, insert the PNG as an image, then position and resize it over the signature line. Acrobat and Preview can also place an image, and because the PNG is transparent it will not cover the ruled line underneath.
How large should the image be?
Draw across most of the canvas rather than in a corner. Scaling a large signature down keeps the edges crisp; scaling a small one up makes the stroke blurry, which is the usual reason a placed signature looks fake.
Can I use this for a signature on a check or a deed?
No. Cheques, deeds, wills and various notarised instruments still require a wet signature or a specific witnessed process depending on where you are. Treat those as paper unless a lawyer tells you otherwise.
