This JPG to ICO converter builds a multi-size Windows .ico file from a JPG image. Select the sizes you want, from 16 up to 256 pixels, and the tool renders each and packs them into one icon whose ICO header is verified before download. It shares the same dependency-free encoder that embeds PNG data in the ICO container and runs entirely in your browser, so nothing is uploaded.
Short answers for the questions people usually have before trying a utility like this.
Yes. Toggle any combination of 16, 32, 48, 64, 128, and 256 pixel sizes before building the ICO.
It will, but each icon is drawn to a square canvas, so a square JPG gives the sharpest, undistorted result.
No. The ICO is created locally in your browser and your file never leaves your device.
Every tool on Cleanor is free with no sign-up, no credits, and no limits. Files are processed privately in your browser. Looking for on-device phone cleanup and Premium features? That lives in the Cleanor app.
