content-types

A library to map file extensions to content types and vice versa.

Installation

pip install content-types

API overview

Forward lookup

Map a filename, bare extension, Path, or URL to its MIME / content type.

• get_content_type: Return the most specific, commonly accepted MIME type for a filename or extension

Reverse lookup

Map a MIME / content type back to its file extension(s) — the inverse of get_content_type.

• guess_extension: Return the canonical file extension for a MIME / content type
• guess_all_extensions: Return every known file extension for a MIME / content type, canonical first

Mapping data

The underlying extension -> content-type table (364 entries; keys have no leading dot).

• EXTENSION_TO_CONTENT_TYPE: dict() -> new empty dictionary

Shortcut constants

Precomputed content types for very common formats, exposed as module-level attributes.

• webp: str(object='') -> str
• png: str(object='') -> str
• jpg: str(object='') -> str
• mp3: str(object='') -> str
• json: str(object='') -> str
• pdf: str(object='') -> str
