Infer file type and MIME type of any file/buffer. No external dependencies.
Project description
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.
Features
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
Installation
pip install filetype

Examples
Simple file type checking
import filetype
def main():
kind = filetype.guess('tests/fixtures/sample.jpg')
if kind is None:
print('Cannot guess file type!')
return
print('File extension: %s' % kind.extension)
print('File MIME type: %s' % kind.mime)
