Tool
ICO to PNG Converter
Extract PNG frames from an ICO favicon file.
Image Tools
What this tool does
Upload an ICO file to extract embedded PNG frames. A single-size ICO downloads as one PNG; multi-size files download as a ZIP of PNGs.
How to use
- Upload a .ico file.
- Process the file in your browser.
- Download the PNG or ZIP of extracted sizes.
Examples
Favicon.ico with three sizes
Input: favicon.ico containing 16, 32, and 48 px frames
Output: ZIP of PNG files at each size
Modern ICO files store PNG-compressed frames that can be unpacked without uploading.
Common use cases
- Edit an existing favicon
- Recover a logo from favicon.ico
- Inspect embedded icon sizes
FAQ
Does this work with BMP-based ICO files?
PNG-in-ICO files extract cleanly. Older BMP-only ICOs fall back to a single browser-decoded PNG when possible.
Will transparency be kept?
Yes for PNG-encoded ICO frames.
Can I convert back to ICO?
Yes. Use the PNG to ICO converter or favicon generator.
