About this tool

Made for the task at hand.

Resolve common document, image, audio, video, font, and archive formats with a small built-in media-type reference.

How to use

  1. Enter extensions or complete MIME types.
  2. Separate multiple lookups with spaces, commas, or lines.
  3. Review mappings and any explicitly unlisted values.
Your work stays yours.

Common questions
Is application/octet-stream returned as a fallback?

No. Unknown values are marked unlisted instead of being assigned a misleading generic type.

Can one MIME type have several extensions?

Yes. Reverse lookup lists every matching extension present in the table, such as jpg and jpeg.
