如何使用 MIME Type Lookup
Enter a file extension (e.g., .pdf, .json, .webp) to look up its MIME type, or enter a MIME type (e.g., application/json) to find its associated extensions. The tool covers hundreds of MIME types used in HTTP headers, email attachments, and web servers. Copy the result for your Content-Type headers.

常见问题
What is a MIME type?+
MIME (Multipurpose Internet Mail Extensions) types identify the format of a file or data. They follow the format type/subtype (e.g., text/html, image/png, application/json). Servers send MIME types in Content-Type headers so browsers know how to handle the response.
Why does MIME type matter?+
If a server sends the wrong MIME type, browsers may refuse to process the file. For example, serving JavaScript as text/plain instead of application/javascript can block script execution. Incorrect MIME types also cause download dialogs instead of rendering.
