Free MIME Type Lookup
Configuring a web server or debugging a download? NToolHub’s MIME Type Lookup maps 60+ common file extensions to their official MIME types, with a note on each type’s typical use. The live search filters as you type, so finding that long application/vnd… string takes seconds instead of a web search.

How to Use the MIME Type Lookup
- Type in the search box to filter by extension, MIME type, or use.
- Browse the full table of 60+ common file types.
- Results update live as you type.
Features
A curated table of 60+ extensions covering documents, images, audio, video, fonts, archives, and code; instant client-side search across extension, MIME type, and description; and monospace-formatted values that are easy to copy.
Benefits & Use Cases
Developers setting Content-Type headers, configuring servers, or building upload validators get authoritative values instantly. Students learning web fundamentals see the real mapping behind file handling.
Tips
Search by use (video, font) when you do not remember the extension. For file uploads, validate against the MIME type, not just the extension — they can disagree. Copy values directly into server configs or HTML accept attributes.
Frequently Asked Questions
What is a MIME type?
A standard label like image/png that tells browsers and servers what kind of data a file contains, so it can be handled correctly.
Why do some extensions have long MIME types?
Vendor-specific formats use structured names, like the Office Open XML types. They are the official registered identifiers.
Can I trust these for server configuration?
Yes, these are the standard registered types. Always verify against your specific server documentation for edge cases.
What if my extension is not listed?
The table covers the most common 60+ types. Rare formats may use application/octet-stream as a generic fallback.
