Frequently Asked Questions

What is a MIME type?

MIME (Multipurpose Internet Mail Extensions) type is a standard identifier for file formats and content types on the internet. Format is 'type/subtype', like 'image/jpeg' or 'application/json'. Browsers and servers use MIME types to determine how to handle files and content.

How do I find the MIME type for a file extension?

Type the file extension (like '.pdf', '.jpg', '.mp4') in the search box. The tool will show you the corresponding MIME type (e.g., 'application/pdf', 'image/jpeg', 'video/mp4') that you should use in Content-Type headers or file upload validation.

What MIME type should I use for JSON?

Use 'application/json' for JSON data. This is the standard Content-Type for REST APIs, AJAX requests, and JSON file downloads. Older applications sometimes used 'text/json', but 'application/json' is the modern, RFC-compliant choice.

What is the difference between image/jpeg and image/jpg?

The correct MIME type is 'image/jpeg'. While some systems accept 'image/jpg', 'image/jpeg' is the official IANA-registered MIME type. Both .jpg and .jpeg file extensions use the 'image/jpeg' MIME type.

How do MIME types affect file uploads?

MIME types help validate uploads by checking if the file's Content-Type matches allowed types. For security, always validate both the MIME type sent by the browser AND the actual file content, as MIME types can be spoofed. Use a whitelist of allowed MIME types for your upload forms.

What MIME types should I use for video files?

Common video MIME types: 'video/mp4' for MP4, 'video/webm' for WebM, 'video/ogg' for Ogg, 'video/quicktime' for MOV. For HTML5 video, MP4 (video/mp4) has the best browser support. Always specify the correct MIME type in Content-Type headers for proper browser handling.
