Reference covers common values and does not inspect a live response or file. Confirm uncommon or newly registered values with the governing registry.
What this tool does
Maps common document, archive, image, audio, video, font and web extensions to the media types normally used in HTTP and files.
How to use it
Search with .json, image/, TrueType or another extension, type prefix or description. Matching media types and extensions appear together.
Example
Searching .json returns application/json, while image/ lists common JPEG, PNG, GIF, WebP, AVIF, SVG, icon and TIFF entries.
Validation
A leading dot is ignored for extension searches. Matching is case-insensitive and uses the curated table without opening or sniffing a file.
How to interpret the result
A MIME type is metadata describing an intended representation. The extension alone cannot prove a file's actual bytes, safety or validity.
Limitations
The reference focuses on common formats and does not include every registered parameter, alias or vendor tree. Consult IANA for authoritative registration data.
Privacy
All processing uses local browser APIs and this tool does not upload the values you enter.
