About this tool
Search a built-in table of common file extensions and their MIME content types, entirely in your browser.
Frequently asked questions
Can I search by MIME type too?
Yes, the filter matches both the extension and the MIME string, so typing image or json narrows the list either way.
What is a MIME type for?
It is the Content-Type label that tells browsers and servers how to interpret a file, such as text/html or image/png.
