Extract images from an ICO
Convert ICO to PNG, or to JPG or WebP. An .ico bundles the same icon at several sizes, and ConvertICO opens the bundle, shows every image inside, and lets you save each size, one at a time or all as a ZIP.
Drop an .ico, or
One .ico. It is opened on your device, never uploaded.
How it works
Inside every .ico is a stack of the same icon at different sizes. Drop one here and ConvertICO opens the stack, decodes each image, and lays them out for you. Pick the output format you want, PNG to keep a transparent background, JPG for the smallest file on a solid photo, or WebP for small files that still keep transparency. Save a single size, or grab the whole set as a ZIP. The file is read in your browser, so it never leaves your machine.
Runs entirely in your browser. Your file is never uploaded.
