What Is ICO Format?

ICO is the icon format used by Windows and web browsers. ICO files contain one or more versions of an icon at different sizes within a single file, allowing the system to pick the most appropriate size for each context. Web browsers use ICO files for favicons, the small icons shown in browser tabs and bookmarks next to a website's name.

Why Convert PNG to ICO?

Favicon creation is the most common reason. Every website needs a favicon. Browsers look for a file named favicon.ico in the website's root directory. Converting your PNG logo or brand mark to ICO produces the file your website needs for this purpose.

Windows application icons require ICO format. Desktop applications display ICO files in taskbar buttons, Start Menu entries, title bars, and file explorer thumbnails. Converting a PNG graphic to ICO creates the icon file that Windows applications use.

PNG is often the best source format for ICO creation because it supports transparency with clean edges, which icons need to display correctly against any background color. Converting from PNG preserves this transparency in the ICO output.
