MIME Types Reference

About this tool

A searchable reference of common MIME (content) types and their file extensions. Filter by extension or type.

Privacy

This tool runs entirely in your browser. Your data is processed locally and never uploaded to a server.

How to use this tool

1. Type a file extension like png or a MIME type like image/png into the search box.
2. Use the filter to narrow results by extension or by type if the list is long.
3. Scan the matching row to see the content type and its common file extensions.
4. Copy the MIME type you need into your code, config, or API request.

Step by step, what happens

1. The tool searches a built-in list of common MIME types and file extensions.
2. It matches your query against both the MIME type string and the extension entries.
3. The results update to show only the entries that fit your search term.
4. Each result presents the type and the extensions it is commonly associated with.

Worked example

A developer wants to confirm the MIME type for a PNG file before setting an HTTP response header.

Input: png

1. Enter png in the search field.
2. The reference filters down to the PNG-related entry.
3. Read the MIME type and the associated file extension from the matching row.

Tips and common mistakes

• Search by either the extension or the MIME type string, whichever you already know.
• If a file type has more than one common extension, check the full row instead of guessing from one extension.
• Use the exact MIME type from the reference when setting headers or configuring uploads.
• If you do not see a match, try a broader term because some types are listed under a more general name.
