Tool Introduction
The MIME Type Lookup is a quick reference for the media types used on the web: the official MIME string, the file extensions that map to it, and a plain-English description. Search by extension (try .pdf, jpg or zip), by the MIME string itself, or by a keyword such as "image", "audio" or "archive".
Use the category chips to browse by type family: Text, Image, Audio, Video and Application. Every entry shows the extensions a server should accept and gives you a one-click copy of the exact MIME value to use in Content-Type headers, upload forms or server config files. Values follow the IANA Media Types registry; a few vendor-specific entries used by older or Chinese office suites are kept for compatibility.
