Why Extract PNG from ICO?
ICO files are favicon containers that bundle multiple image sizes (16×16, 32×32, 48×48, 64×64, 128×128, 256×256) into a single file. Browsers pick the right size automatically, but if you need one of those images as a standalone PNG — for a design file, presentation, or to identify a website's icon — you need to extract it. This tool reads the ICO binary, finds every embedded image, and lets you download each one as a clean PNG.
Standard ICO Sizes
| Size | Typical Use |
|---|---|
| 16×16 | Browser tab favicon, bookmarks |
| 32×32 | Windows taskbar, address bar |
| 48×48 | Windows desktop shortcut |
| 64×64 | High-DPI taskbar icons |
| 128×128 | macOS dock icons |
| 256×256 | Windows Vista+ high-res icons |
How ICO Files Work
Modern ICO files embed each image either as a standard PNG (for 256×256 and sometimes 128×128) or as a Windows BMP/DIB (for smaller sizes). This tool handles both formats — BMP-encoded images are decoded and rendered to canvas before being exported as PNG.
