How to use MIME Type Lookup
- Enter a file extension, filename, or MIME type you want to identify.
- Run the lookup and review matching content types or extensions.
- Use the result when setting headers, upload rules, validation, or documentation examples.
Why use MIME Type Lookup
MIME types tell browsers and clients how to handle files. A wrong content type can make downloads fail, scripts refuse to execute, SVGs render incorrectly, or uploads be rejected by validation rules.
This lookup is a quick reference for common web formats. Server configuration and security policy still matter, so verify important production responses with a headers checker after changing MIME settings.
Best for MIME Lookup
- Choosing content-type headers for static files.
- Checking upload allowlists and validation rules.
- Finding likely extensions for a MIME value.
Practical notes
- Some formats have multiple accepted MIME values.
- Do not trust uploaded file extensions for security decisions.
- Confirm live responses with an HTTP header check.
