About this tool
Looks up common file extensions and returns their MIME types, categories and whether browsers handle them safely. It covers documents, images, audio, video, archives and web assets, with a clear “unknown” answer instead of a guess.
How to use it
- Type an extension such as webp, or a MIME type.
- Read the matching entries and categories.
- Copy the MIME type into your server configuration.
Frequently asked questions
Why do some types have several forms?
Legacy types such as application/javascript and text/javascript coexist. Prefer the modern IANA value.
Can I rely on the MIME type for security?
Never. Validate uploaded files by content and extension, and do not trust the client-supplied Content-Type.
