Prepare a signature for an upload
Photograph your signature on white paper, and this cleans the paper away, crops to the ink and hits the size the form asks for. It runs in the browser, so the signature never leaves your device.
- Free, no limits
- Processed in your browser
- Never sent to a server
- No sign-up
Nothing is uploaded because nothing needs to be. Cropping happens on a canvas in your browser, and the background is removed by a neural network that downloads to your device and runs there. The only thing that travels is the model coming down — your photo never leaves the tab, and the source code is public so this can be checked rather than believed.
Why a separate page
Forms that ask for a signature state the pixel width and a range in kilobytes, and the range has a floor as well as a ceiling — a clean signature compresses so well that it falls under the minimum and is refused for being too small. That is the half of the rule most tools ignore, so it is a control here rather than a surprise.
