Zero data retention The name you send is turned into a signature in memory and returned in the same response. It is never written to a database, a log or a disk, and neither is the image. The only thing Handsign keeps is a counter for your quota: when a signature was made, with which style and size. Details in the Terms
How it works Our own model, trained on thousands of real handwritten signatures, draws the name. A text recognition model reads each take back; when a take does not read as the name, the model draws again, and the best take is returned in the ink color and pen weight of your choice, as a PNG with a transparent or white background or as an SVG outline.
Known limits It is a generative model. Despite the reading check, a signature can still come back with a misspelled letter or a stray mark. The X-Signature-Legible header tells you when the reader could not confirm the text, and we are correcting these details with every version.
Options Five styles (natural, elegant, flourish, bold, scrawl), six pens (ballpoint, gel, fineliner, fountain, marker, pencil), any ink color, a transparent or white background, four widths (S 128 px, M 256 px, L 512 px, XL 768 px) at 1x, 2x or 3x pixel density, as PNG or SVG.
