🔁 Convert PNG to ICO
About these formats
About PNG. PNG is a lossless format with full transparency support, which makes it ideal for logos, icons, screenshots and graphics with sharp edges or flat colour. Files are larger than lossy formats because no detail is discarded.
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 PNG 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 PNG as a master copy.
