ANIM (.anim)
.anim file signature | application/octet-stream
ANIM is a legacy animation file format for the Amiga platform, developed by Electronic Arts as an extension of the Interchange File Format and documented through historical Amiga software references. It was used to store frame-based animations, cartoons, demos, and multimedia sequences in applications and games. The format is largely obsolete today, and while it is generally safe to inspect, support is limited in modern software and may require legacy-compatible tools.

Frequently Asked Questions
What is a .anim file?
A .anim file is identified by the magic bytes 46 4F 52 4D at byte offset 0. ANIM is a legacy animation file format for the Amiga platform, developed by Electronic Arts as an extension of the Interchange File Format and documented through historical Amiga software references. It was used to store frame-based animations, cartoons, demos, and multimedia sequences in applications and games. The format is largely obsolete today, and while it is generally safe to inspect, support is limited in modern software and may require legacy-compatible tools.
What are the magic bytes for .anim files?
The magic bytes for ANIM files are 46 4F 52 4D at byte offset 0. These bytes uniquely identify the file format regardless of the file extension.
How do I validate a .anim file?
To validate a .anim file, read the first bytes of the file and compare them against the known magic bytes (46 4F 52 4D) at offset 0. This is more reliable than checking the file extension alone, as extensions can be renamed.
What is the MIME type for .anim files?
There is no officially registered MIME type for .anim files. Systems typically use application/octet-stream as a generic fallback when handling this format.
Is it safe to open .anim files?
ANIM (.anim) files are generally safe to open. They are classified as low risk because they primarily contain data rather than executable code. However, always ensure files come from a trusted source.
