FontCrafter is a free online tool that allows users to create a font from their own handwriting. The tool uses JavaScript to process the handwriting locally in the browser, without requiring an account or uploading any data to servers. Users can print a template, fill it in with their handwriting, and then upload it to the website to generate a font. The generated font can be downloaded in various formats, including OTF, TTF, WOFF2, and Base64.
