About MIME Type Lookup

MIME Type Lookup resolves file extensions and paths to candidate media types, or returns known extensions and metadata for a complete Content-Type value.

How it works

Bidirectional lookup

Enter an extension, dotted extension or filename to find matching media types. Enter a type/subtype value to retrieve its extensions, or a top-level wildcard such as image/* for a bounded category listing.

Registry-backed metadata

Results come from a pinned mime-db dataset aggregated from IANA registrations plus Apache and nginx mappings. Each match identifies its source, known extensions, default charset and compressibility when available.

Ready-to-use Content-Type

A Content-Type value is assembled for each match, including the database's default charset. Parameters on input types are ignored for lookup so copied HTTP header values work directly.

Frequently asked questions

Can one extension have several MIME types?

Yes. All dataset matches are shown, with IANA registrations ranked before web-server or custom mappings.

Does this inspect file contents?

No. Filename lookup uses the extension only. Determining a binary file's real format requires signature or magic-byte inspection.

Why is compressibility sometimes unknown?

Not every registered media type declares a general compression recommendation, and actual benefit also depends on the specific payload.
