About the ICO format
ICO (.ico, MIME type image/x-icon) is one of 38 image formats Convert Me Pls supports. ICO is the Windows icon format — it packs several small sizes into one file and is what browsers request as a favicon.
Working with ICO files
Whether you need to open a ICO file in software that doesn't support it, shrink it for the web, or hand it to a service that demands a specific format, the converters below cover every supported route — to and from ICO — for free, online, with no sign-up and no watermarks.
How Convert Me Pls handles ICO
Image conversions use libvips and ImageMagick, preserving colour profiles, transparency and metadata wherever the destination format allows — all on a fast, secure server.
