MIME Type Lookup

What a MIME type is

A MIME type (also called a media type or content type) is a short label like image/png or application/json that tells software what kind of data a file holds. Servers send it in the Content-Type header, browsers use it to decide how to open a response, and APIs rely on it to accept or reject uploads. It has two parts — a top-level type such as text, image, audio, video, application or font, and a subtype such as html, jpeg or pdf. Because the file extension alone is only a hint, knowing the matching MIME type is what lets you set the correct header.

How to use this lookup

Type into the search box to filter the table live. Enter an extension like svg to see it maps to image/svg+xml, or paste part of a MIME type like application/ or video/ to list every matching row. A leading dot is ignored, so .mp4 works the same as mp4, and matching is case-insensitive. Each row has a Copy button that puts the MIME type on your clipboard, ready to drop into a server config, fetch call or upload allow-list.
