What is a .agc file?
The AGC file format was an early image format used by Apple computers, particularly during the Macintosh era. It was designed to store simple graphics and icons, often used for user interface elements. While it was common in its time, it has largely been superseded by more modern and versatile image formats. These files typically contain bitmap data and some basic metadata related to their display. Due to its age and limited feature set, direct support for AGC files is rare in contemporary software.

Directly opening AGC files is difficult. You will likely need to use an emulator or convert the file if possible.
Technical Details
AGC files are essentially uncompressed bitmap images. They store pixel data directly, often with a fixed color depth. The file structure is relatively simple, containing image dimensions, color information, and the raw pixel data. Some variations might include rudimentary header information for the Macintosh operating system to interpret the image.
