Convert JPG to ICO Online
Need to turn a JPG file into ICO? JPG (also written JPEG) is the world's most widely supported photo format. It uses lossy compression that throws away detail the eye barely notices, which keeps photographic files small while staying compatible with virtually every device, browser and app. ICO is the Windows icon container. It bundles several small sizes of the same image (16px up to 256px) into one file so the operating system or a browser can pick the right one for a favicon or app icon. Converting from JPG to ICO bridges the two: you keep the picture, but in a format that fits where you are taking it.

What to expect converting JPG to ICO
The result is tiny because icons are capped at 256x256 or smaller, often only a few kilobytes.
The photo is downscaled to icon dimensions, losing most detail, and any non-square cropping must be handled first.
You need a favicon or Windows application icon derived from a logo or image.
You want to display the picture at normal size, since ICO is strictly for small icon use.
