What it is AI-extracted, prompt v1, taxonomy v1, 2026-08-30, confidence not recorded

A comprehensive JSON database of MIME/media types aggregated from IANA, Apache, and nginx sources. It contains no logic, just a single public JSON file mapping MIME types to extensions, charsets, and compressibility info.

Use cases

  • look up file extensions for a mime type
  • determine the default charset for a content type
  • check whether a mime type is compressible with gzip
  • build a file upload type validator
  • map file extensions to content types in an http server

When to avoid

  • you want a library that resolves MIME types from file paths with an API - use mime-types or mime instead
  • you need custom or non-standard media type mappings not in IANA/Apache/nginx
