Convert JPG Images to ICO Format

This tool converts JPEG (.jpg, .jpeg, .jfif) images into standard Windows icon (.ico) files. While browsers and operating systems use ICO files for website favicons, desktop shortcuts, and executable icons, they cannot use raw JPEG files directly in place of an ICO container.

Single Size vs. Multi-Resolution ICO

An ICO file is a container that can hold either a single bitmap/PNG image or several resolutions side by side. You can pick a specific pixel dimension from 16×16 up to 256×256, or choose the Multi-size option to pack 16×16, 32×32, 48×48, 64×64, 128×128, and 256×256 layers into a single .ico file:

  • 16×16 & 32×32: Classic browser tab favicons, bookmark lists, and Windows Explorer detail/list views.
  • 48×48 & 64×64: Standard desktop shortcut icons and taskbar buttons on high-DPI displays.
  • 128×128 & 256×256: Large and extra-large icon views in Windows File Explorer.

Tips for Better Icons from JPEG

Icons are square, so if your source JPG is rectangular, you may want to crop the image to a 1:1 square aspect ratio before converting so it fills the icon canvas cleanly. Because JPEG does not support alpha transparency, the generated icon will have a solid background. If you need a transparent background around your logo or object, use our background remover or convert a transparent PNG using PNG to ICO.
