//how_it_works
How It Works
Drop your ICO files
Drag and drop or select ICO icon files. Standard Windows icons and favicon.ico files are both supported.
Browser extracts the icon
Your browser's native ICO decoder reads the container and renders the highest resolution image variant onto an HTML Canvas with full transparency.
PNG export with alpha
The Canvas exports as a 32-bit PNG (24-bit color + 8-bit alpha) with DEFLATE compression. Transparency is fully preserved from the original ICO.
Download your PNGs
Your universal PNG icons are ready. Use them in web design, cross-platform apps, design tools, or anywhere ICO isn't supported.
// under the hood
ICO files use a container format that can store multiple bitmap or PNG-compressed images at different sizes (16x16 to 256x256). Our converter uses the browser's native ICO decoder which renders the highest resolution image stored in the container onto an HTML Canvas, then exports as a 32-bit PNG with DEFLATE compression and full alpha channel transparency support.

Frequently Asked Questions
- What is ICO format?
- ICO is the icon file format used by Windows for application icons, desktop shortcuts, and favicons. An ICO file can contain multiple image sizes (16x16, 32x32, 48x48, 256x256) in a single file. ICO is primarily a Windows format and has limited support on other platforms.
- Why convert ICO to PNG?
- PNG is universally supported across all platforms and browsers, while ICO is limited to Windows. Converting to PNG lets you use icons in web design, macOS/Linux apps, design tools like Figma, and any platform that doesn't support ICO natively.
- Which size is extracted from the ICO file?
- Our converter renders the largest available size from the ICO file. If the ICO contains a 256x256 image, that's what you'll get. The browser's decoder automatically selects the highest resolution variant stored in the ICO container.
- Can I use the PNG as a favicon?
- Yes! Modern browsers support PNG favicons directly via the link tag with type image/png. You can use the converted PNG as a favicon without converting back to ICO. Most modern websites use PNG favicons.
- Is my data private?
- Yes. All conversion happens locally in your browser using the Canvas API. Your ICO files never leave your device — we have zero access to your files at any point.
