What is MIME Type Lookup?

MIME Type Lookup is a bidirectional reference tool that converts between file extensions and MIME types. It uses the official IANA mime-db standard database to provide accurate, reliable results instantly in your browser without server processing.

How do I use the MIME Type Lookup tool?

Enter either a file extension or MIME type in the search field. For extensions, you can include or omit the leading dot (both 'pdf' and '.pdf' work). For MIME types, enter the full type like 'application/pdf' or 'image/jpeg'. The tool instantly displays the corresponding result with additional information about the type.

Can I lookup both file extensions and MIME types?

Yes, the tool works bidirectionally. You can search by file extension to find its MIME type, or search by MIME type to find associated file extensions. This flexibility makes it useful for both development and server configuration scenarios.

Is the data accurate and up-to-date?

All MIME type data is sourced from the official IANA mime-db database, which is the standard reference for internet media types. This ensures accuracy and compliance with current internet standards and conventions.

Is MIME Type Lookup free?

Yes, this tool is completely free to use at tools.bkns.vn with no registration or limitations required.

This tool operates entirely in your browser with no server-side processing required. Simply enter either a file extension (e.g., 'pdf', 'jpg', 'mp4') or a MIME type (e.g., 'application/pdf', 'image/jpeg', 'video/mp4') into the search field, and the tool instantly displays the corresponding result.

The lookup database is powered by IANA's official mime-db, ensuring accuracy and compliance with internet standards. The bidirectional search capability means you can work in either direction: convert extensions to MIME types for HTTP headers and content-type configurations, or find appropriate file extensions when you only have a MIME type.

Results are returned instantly without any network delay, making this tool ideal for rapid development and server configuration tasks. The tool handles common variations including formats with or without leading dots and case-insensitive queries.
