MIME Type Lookup
Find the MIME type of a file extension, or the extensions for a MIME type.
What is a MIME type?
A MIME type (Content-Type) is the standard label that says what kind of content a file contains, such as image/webp, application/pdf or text/html. Web servers send it to the browser to decide whether a file is displayed, downloaded or executed.
Why it matters
The wrong MIME type can stop CSS from loading, videos from playing, files from downloading or trigger security policies. You need the right type when configuring Nginx, Apache or IIS, writing upload validation and building API responses.
Two-way search
Enter an extension (.webp or webp) to get the MIME type, or a MIME type to get its extensions. The list is built into the tool and searches run in your browser.
How to use MIME Type Lookup
- Type an extension or MIME type into the search box.
- Matching results are listed.
- Find the MIME type or extension you need.
- Copy it into your configuration.
Why use this tool?
No more searching for the right Content-Type for server configs and upload code.
FAQ
Do I need the dot in the extension?
No. Both .webp and webp work.
Which MIME type is used for unknown files?
application/octet-stream is used for generic binary files.
How do I find a file's real type?
Use the File Type Detector, which looks at the content rather than the extension.
