Three ways to make your signature
Drawing is the most direct. On a phone or tablet you sign with your finger or a stylus, just as you would on a delivery driver's screen; on a computer you use the mouse or the trackpad. If the first attempt looks shaky, clear it and try again until it looks like yours.
Typing suits people who don't want to draw. Write your name and choose one of three handwriting styles. These styles use the cursive fonts already installed on your device, so the same name can look different on an iPhone, an Android phone and a Windows laptop. What you see in the preview is exactly what you download.
Uploading is for those who want their real pen signature. Sign on white paper, take a photo, and the tool removes the light background and keeps the strokes. A slider adjusts how much is removed, which helps with gray paper or uneven light.
A transparent PNG that sits on any document
The download is a PNG with a transparent background, trimmed to the edge of the signature so there is no empty space around it. Transparency is what makes it useful: placed over a line in a contract or over the text of a letter, only the ink shows, without a white box covering what is underneath.
You can choose black or blue ink. Blue is often preferred on printed paperwork because it stands out from black text. For an uploaded photo you can also keep the original color of your pen.
Where to use it
Insert the PNG as a picture in Word, Google Docs or Pages to sign a letter, a quote or an authorization. Add it to an email signature under your name. Drop it into invoices and proposals you send every week instead of printing, signing and scanning each one.
For a PDF, “Sign PDF” on this site places a signature on any page, and “Edit PDF” inserts the PNG as an image. Keep the file in a safe place: once made, you can reuse it as often as you like.
What kind of signature this is
The result is an image of your signature, what is usually called a simple electronic signature. It is not a digital signature backed by a certificate, it does not verify your identity, and it does not lock the document against changes.
Many everyday documents are signed this way, but some procedures require a certificate-based digital signature or a signature on paper. If in doubt, ask whoever will receive the document what they accept.
Private by design
A signature is something to be careful with. Everything here happens in your browser: what you draw, type or upload is not sent to a server and is not stored. There is no account and no email to give, and the tool is free with no limit on use.
