Small and dependency free Python package to infer file type and MIME type checking the magic numbers signature of a file or buffer.
This is a Python port from filetype Go package.
- Simple and friendly API
- Supports a wide range of file types
- Provides file extension and MIME type inference
- File discovery by extension or MIME type
- File discovery by kind (image, video, audio…)
- Pluggable: add new custom type matchers
- Fast, even processing large files
- Only first 261 bytes representing the max file header is required, so you can just pass a list of bytes
- Dependency free (just Python code, no C extensions, no libmagic bindings)
- Cross-platform file recognition
