Binary Parsing of Windows Icon Containers

A single .ico file can conceal multiple individual image streams. Imgora parses the 6-byte ICONDIR header, reads each 16-byte ICONDIRENTRY record, and resolves image byte offsets to isolate every resolution frame. Both PNG-compressed payloads (standard in 256×256 icons) and legacy DIB bitmap frames are unpacked with full color depth.

Preserving Embedded Alpha Channels

All unpacked frames are exported as individual 32-bit PNG files with intact transparency, making them ready for UI mockups in Figma, icon design workflows, or web deployment.
