How It Works

ICO is the native icon format for Windows applications and the classic favicon format for websites. Unlike single-image formats, ICO files can contain multiple sizes in one file, allowing Windows to select the appropriate size for each context (taskbar, desktop, file explorer, etc.). Our converter lets you select which sizes to include (16x16, 32x32, 48x48, 64x64, 128x128, 256x256) and packages them into a single ICO file. PNG source images with transparency will maintain their transparency in the ICO output.
