Draw your signature with a finger or a mouse, or type your name in a handwritten face, and save it as a transparent PNG that drops cleanly onto any document.
Sign on the pad with a finger, a stylus or the mouse. If you would rather type, switch tabs and pick a hand you like.
Black for most things, blue where a document is expected to be signed in blue. Adjust the pen thickness so it looks like your own hand.
The empty space around the signature is trimmed off, so it sits at a sensible size when you place it. From there you can go straight to signing a PDF.
A signature saved as the whole drawing area is mostly empty space. Drop that onto a contract and the visible ink ends up tiny in the middle of a large transparent rectangle, so you scale it up until it fits and it turns soft and blocky.
This finds the edges of the actual ink and cuts to those, leaving a small margin. The result is a file whose size is the signature, which places at a natural scale and stays crisp.
The pad is drawn at well above screen resolution for the same reason. A signature captured at the size it appears on your screen looks fine on that screen and ragged the moment it is printed, so what you save is considerably larger than what you drew on.
No. The work happens inside this tab, on your own machine. Open your browser's network tab while you use the tool, there is no request carrying your file.
Practical limits depend on the tool, browser and available device memory. Large files can fail even when no explicit limit is shown. Keep an original and use a smaller job if this device cannot finish it.
No, and there is no daily limit either. There is nothing to sign up for.
Yes, it is a PNG with an alpha channel, so only the ink shows. Place it over a form and the lines underneath stay visible.
That depends entirely on the document and the country, not on how the image was made. For anything that matters, check what the other party requires before you rely on it.
Yes. Save the PNG, then open the Sign PDF tool and drop it on the page where you want it.
Draw on the pad with a mouse, a finger or a stylus, choosing the pen thickness from 2 to 12 and an ink of black, blue or bright blue. Or switch to Type, write your name and pick a script style. The result is cropped to the ink with a small margin and saved on a transparent background.
Drawing with a finger or a stylus gives a far more natural line than a mouse. Clear the pad and try again until it looks like you.
The file is always signature.png, and the tool links straight to Sign PDF, where you can place it on a document. Typed signatures use script fonts that are installed on your device, so the same name can look slightly different on another computer.
It is an image of a signature, not a certified or digital signature. Anyone who gets the file can reuse it, so keep it somewhere private and do not post it publicly. The transparent background lets it sit on a page without a white box around it.
