What JPG to ICO conversion does

Convert a JPG, JPEG, or JFIF image to a Windows ICO icon directly in your browser. Generate a single size, or the default multi-size package covering 16, 32, 48, 64, 128, and 256 px in one .ico file.

How to convert JPG to ICO

  1. Choose a JPG, JPEG, or JFIF file.
  2. Pick a single icon size, or leave the default multi-size package selected.
  3. Select Convert & download.
  4. Save the .ico file from your browser downloads.

Why use this conversion

ICO is the format Windows expects for application icons, desktop shortcuts, and favicons. A single square photo can be turned into a real, multi-resolution .ico file ready to use.

Transparency and output quality

This is a real ICO container (ICONDIR plus one entry per size), with each size embedded as genuine PNG-compressed image data, not a JPG file with a renamed extension. Each icon entry uses PNG compression, so a single-size ICO stays small; the multi-size package is larger since it bundles six images.

Privacy and local processing

  • Processing occurs locally in the browser.
  • Files are not uploaded to Looty Tools for conversion.
  • Converted files remain on your device.

Limits and known issues

  • Input: JPG, JPEG, or JFIF (.jfif, .jfi, .jif), up to 25.0 MB and 8,192 px per side.
  • Each icon size is generated by resizing the full image to a square canvas, so a non-square source will be stretched to fit. For best results, start from a square, cropped image.
  • JFIF (.jfif, .jfi, .jif) is accepted alongside .jpg and .jpeg because it is a JPEG-based format.
  • Metadata is not preserved in the downloaded file.
