About HTTP status codes & MIME types

HTTP status codes are three-digit numbers a server returns to describe the result of a request — 200 OK, 404 Not Found, 500 Internal Server Error, and so on. MIME types (like application/json or image/png) tell the browser what kind of content it received. This reference bundles the standard codes and the most common MIME types so you can look them up without leaving your editor.

Frequently asked questions

What is the difference between an HTTP status and a MIME type?
A status code describes the outcome of a request. A MIME type in the Content-Type header describes the format of the response body.
Can I search by file extension?
Yes. In the MIME tab, searches such as json, png, pdf, or xlsx match the bundled common content types.
Does this page make an HTTP request to test a URL?
No. It is an offline reference table and does not inspect endpoints or response headers.
