🔁 Convert JPG to ICO
About these formats
About JPG. JPG (JPEG) is a lossy format tuned for photographs. It produces small files and opens on practically every device and app ever made, but it cannot store transparency and re-saving repeatedly slowly degrades quality.
About ICO. ICO is the multi-resolution icon container browsers load as a site favicon. A single .ico bundles several sizes so the browser can pick the sharpest one.
Your JPG image is rendered at several small sizes and packed into a single ICO file, ready to serve as a website favicon.
When to keep the original instead. There is no quality penalty to worry about here, but it is still wise to keep the original JPG as a master copy.
