This JPG-to-ICO converter runs entirely in your browser. Your images never leave your computer — there is no upload, no account, no watermark and no file-size paywall — and it keeps working offline after the first load. The .ico is written with several square sizes inside it (16, 32 and 48 pixels by default), which is what Windows and browser tabs expect.
