Step-by-step conversion
- Open /tools/jpg-to-ico.
- Choose a JPG, JPEG, or JFIF file — the content is validated as real JPEG-family data before conversion.
- Pick a single icon size, or leave the default multi-size package (16–256 px) selected.
- Select Convert & download.
Square dimensions
Each icon size is generated by resizing the full image to a square canvas, so a non-square photo will be stretched to fit — start from a square, cropped image for best results. Each entry is real PNG-compressed image data, not a renamed JPG.
Privacy
Conversion runs locally in your browser. The file is not uploaded to Looty Tools servers for this workflow.
Convert JPG to ICO FAQ
- Can I generate a multi-size ICO?
- Yes, and it is the default: 16, 32, 48, 64, 128, and 256 px bundled in one .ico file. You can also pick a single size.
- Does this accept JFIF files?
- Yes. JFIF is a JPEG-based format, so .jfif, .jfi, and .jif files are accepted alongside .jpg and .jpeg.
- Is this a real ICO file?
- Yes — a real ICO container (ICONDIR plus one entry per size), with each size embedded as genuine PNG-compressed image data.
- What happens if my photo isn’t square?
- It is stretched to fit each square icon size. Start from a square, cropped image for the best result.
- Are my files uploaded?
- No. Conversion runs locally in your browser and does not upload your file to Looty Tools servers.
