About the MIME Types Reference Tool
MIME (Multipurpose Internet Mail Extensions) types are a standard way to identify the format of files on the internet. Every time your browser loads a resource, receives an API response, or downloads a file, the MIME type tells it how to handle that content. Using the correct MIME type is critical for web development, server configuration, email systems, and API design. Our MIME Types Reference Tool provides instant lookup of all common MIME types organized by category.
Whether you are configuring your web server, setting Content-Type headers in an API, or debugging why a file isn't displaying correctly, having a reliable MIME type reference is essential. This tool contains hundreds of MIME types covering documents, images, audio, video, archives, fonts, and application-specific formats.
How to Look Up MIME Types
Enter a file extension: Type any file extension (with or without the dot) into the lookup field and click "Lookup" to see its MIME type.
Search the database: Use the search box to filter the entire database by extension name, MIME type string, or description.
Browse by category: Click category tabs to filter results by Document, Image, Audio, Video, Archive, Font, or Application types.
Copy the Content-Type: Use the generated Content-Type header directly in your server configuration or API responses.

Why MIME Types Matter for Web Development
Incorrect MIME types can cause a wide range of issues: browsers may refuse to render images, JavaScript files may be blocked by security policies, CSS stylesheets may not load, and API responses may be misinterpreted. Modern web servers, CDNs, and browsers all rely on accurate MIME type declarations to function correctly. A misconfigured Content-Type header can break your entire application or expose security vulnerabilities.
Use Cases
Server ConfigurationConfigure Apache, Nginx, or IIS with the correct MIME type mappings for your content.
API DevelopmentSet accurate Content-Type headers in REST and GraphQL API responses for proper client handling.
Email SystemsConfigure email servers with correct MIME types for attachments and embedded content.
CDN SetupEnsure content delivery networks serve files with correct headers for caching and rendering.

Frequently Asked Questions
A MIME type (Multipurpose Internet Mail Extensions) is a standard identifier that tells browsers, email clients, and servers how to handle a file. It consists of a type (e.g., "application") and a subtype (e.g., "pdf"), forming "application/pdf".
Using the wrong MIME type can prevent browsers from rendering content, block file downloads, cause CORS errors in APIs, and even create security vulnerabilities. Modern browsers strictly enforce MIME type checking for scripts and other resources.
For Apache, use AddType directives or .htaccess files. For Nginx, use the types{} block in your config. For IIS, use the mimeMap element in web.config. Most servers have default MIME type mappings that you can extend.
This tool covers the most commonly used MIME types. For rare or proprietary formats, consult the official IANA MIME Media Types registry or the specific format's specification document.
