MIME Type Lookup
Search 71 practical extension mappings for web assets, documents, images, media, and fonts. The reference primarily uses IANA-registered media types and separately marks conventional types outside that list. Data was checked on September 21, 2026.
Key features
- Search extensions and types such as .png, js, and application/json.
- Prioritize exact extension or type matches, then use partial matching for other searches.
- Show associated extensions and distinguish registry entries from conventional types.
How to use
- Enter an extension or MIME type; use * to browse all entries.
- Review the suggested type and its registration label.
- Use it as a server configuration reference, while separately checking actual content and application requirements.
Use cases
- Look up Content-Type values for static assets.
- Prepare explanatory extension lists in an upload interface.
- Check current registered types for JavaScript and YAML.
Frequently asked questions
Does it identify the actual format of a file?
No file is uploaded or inspected. An extension reference cannot determine content, safety, or playback compatibility.
Does each extension have exactly one MIME type?
No. Containers, codecs, usage, and server configuration can affect the appropriate type. Entries provide representative mappings rather than certainty from a filename.
Which types are listed for JavaScript and YAML?
The reference uses text/javascript and application/yaml, distinguishing them from historical forms such as application/javascript and text/x-yaml.
What does outside the IANA list mean?
Some entries follow format documentation, such as WebM, or common implementation conventions. They are not equivalent to IANA registration, and this tool is not a complete copy of the IANA registry.
