JPG to ICO converter
Turn a JPG (or PNG) into a Windows .ico icon — all sizes, locally, no upload.
Convert JPG to ICO in your browser
ICO is the classic Windows icon format used for favicons and application or shortcut icons. It can hold several sizes in one file so the system always has a crisp icon — whether shown at 16 px in a browser tab or larger on the desktop. This tool turns any JPG (or PNG) into a multi-size .ico.
Everything is rendered in your browser on the canvas, so your image is never uploaded. You get the classic .ico containing 16, 32 and 48 px, plus matching PNG sizes for modern browsers and home screens — ready to drop into your site or project.
For a sharp icon, start from a square image with a simple, high-contrast design — fine detail disappears at 16 px. If your JPG isn’t square, crop it first so nothing important is clipped.
