ICO to PNG Converter

Convert Windows ICO icon files to PNG images in your browser. ICO files often contain multiple embedded sizes; this tool lists each one so you can preview and download the version you need for web design, app assets, or documentation. To create ICO files from JPG images, use our JPG to ICO Converter.

How ICO extraction works

An ICO file stores a directory of one or more images. Modern icons are usually PNG-encoded inside the container, while older icons may use BMP format. This tool reads the ICO structure and exports the selected embedded image as PNG.

Typical use cases

Extract favicon sizes for websites and PWA manifests.
Recover PNG assets from legacy application icon packs.
Preview all sizes before choosing the best resolution.

Frequently Asked Questions

Can I convert PNG back to ICO?

Yes. Use our PNG to ICO Converter or JPG to ICO tools.

Why does one ICO show multiple sizes?

ICO is a container format. Developers embed several resolutions so icons look sharp at different display sizes.

Are uploaded icons stored on a server?

No. Parsing and conversion happen locally in your browser.

What if my ICO uses BMP encoding?

The tool still extracts the embedded image. Most browsers can preview BMP-based icon data from ICO files.
