Extract PNG images from ICO files, free, no upload required
Drop an ICO file and extract all the PNG images embedded inside it. Each size is available to download individually. Works with website favicons and Windows application icons. Runs entirely in your browser.

Each size embedded in the ICO file is extracted as a separate PNG. Most favicons contain 2 to 4 sizes.

ICO is Microsoft's icon container format, introduced with Windows 1.0 in 1985. It stores one or more images at different sizes and color depths so the operating system can pick the best version for each context: browser tab, taskbar, desktop shortcut, and so on.
Modern ICO files use PNG data internally. When you convert a PNG to ICO and embed multiple sizes, the ICO file is essentially a wrapper around those PNG blobs. This tool unwraps them and gives you back each embedded PNG as a standalone file.
Website favicons
favicon.ico files typically contain 16x16, 32x32 and sometimes 48x48 PNG images.
Windows application icons
App ICO files often include 16, 32, 48, 64, 128 and 256 pixel sizes for different display contexts.
Older bitmap ICO files
Pre-Vista ICO files contain BMP data instead of PNG. These extract as PNG but may have slight rendering differences.
Minimal favicons
Some websites only embed a single size, usually 32x32 or 48x48. The tool extracts whatever is present.
An ICO file is a container that holds one or more images at different sizes. Historically these were bitmap images, but since Windows Vista, ICO files commonly embed PNG images directly. A typical website favicon.ico contains 2 to 4 sizes, usually 16x16, 32x32 and sometimes 48x48. This tool extracts each embedded image as a separate PNG file.
Common reasons: you want to use a website's favicon in another context (presentation, document, design file), you are editing an existing favicon and want the source image, you have an application icon and need it as a PNG for use in other software, or you are debugging why a favicon looks wrong at a particular size.
It depends on what sizes are embedded in the ICO file. A simple favicon might contain 2 to 3 sizes. A Windows application icon might contain 6 or more. The tool extracts all sizes it finds and lets you download each one individually.
No. The extraction runs entirely in your browser using the icojs library. Your ICO file never leaves your device.
The tool extracts every image embedded in the ICO file. If you expected more sizes, the original ICO file may not contain them. Not all ICO files contain all sizes. Some minimal favicons only embed 16x16 and 32x32.
