.ami — Amiga IFF Bitmap
Commodore · 1985
.ami files are legacy bitmap image files primarily used on older Commodore Amiga computers, often containing graphics for games and applications.
Key Features
- Flexible container for various data types.
- Supports multiple color depths and resolutions.
- Incorporates image-specific headers (BMHD).
- Can utilize various compression methods.
Best For
- Preserving original Amiga game assets.
- Retro computing enthusiasts.
- Archiving graphics from the early Amiga era.
Less Ideal For
- Web use due to limited browser support.
- High-quality print graphics.
- Modern digital photography.
- Sharing across diverse operating systems without conversion.
Common Use Cases
- Storing graphics for Amiga video games.

How to Open It
- Use image editing software that supports IFF/ILBM, such as GIMP or IrfanView on modern operating systems.
- Amiga emulators like UAE (Universal Amiga Emulator) can often open these files within their native environment.
- Online converters can sometimes convert .ami files to more common formats like PNG or BMP.
What is a .ami file?
The .ami file extension is associated with the Interchange File Format (IFF), a flexible container developed by Electronic Arts for the Commodore Amiga computer. IFF was designed to store various types of data, but it's most commonly recognized for its use in storing bitmap images. These images could include graphics for games, applications, or general desktop use on the Amiga. While it was a groundbreaking format for its time, offering features like color palettes and different compression methods, it has largely been superseded by more modern image formats.

Frequently Asked Questions
IFF (Interchange File Format) is a flexible container format developed by Electronic Arts, widely used on Commodore Amiga computers to store various data types, including images (ILBM).
No, .ami is a legacy format primarily associated with the Amiga computer and is rarely used for new projects today.
Yes, with appropriate software like GIMP, IrfanView, or an Amiga emulator, you can often view and convert .ami image files.
Technical Details
IFF is a container format, meaning it can hold various data chunks. For images, the 'BMHD' (Bitmap Header) chunk defines image properties, and 'BODY' contains the pixel data. It supports different color depths, resolutions, and can utilize compression algorithms like ILBM (Interleaved Bitmap) compression, which is a form of run-length encoding.
