MIME (Multipurpose Internet Mail Extensions) type is a standard identifier that indicates the format and content type of a file. It is transmitted via the Content-Type header in HTTP protocol, helping browsers correctly parse and display files.
Both MIME types and file extensions identify file formats. Extensions (.html, .jpg) are used at the OS level, while MIME types (text/html, image/jpeg) are the standard at the network transmission level. Servers use MIME types to tell browsers how to interpret received data.
You can search by file extension (e.g., .pdf, .docx) or keyword (e.g., image, text) in this tool to find the corresponding MIME type. You can also reverse-lookup which extensions belong to a MIME type.
MIME types are categorized: text/ for readable text, application/ for binary or application-specific data, image/, audio/, video/ for media files. Each category has its standard prefix.
Incorrect MIME type configuration can cause browsers to fail parsing files properly - files may download instead of display, show garbled content, or be blocked by security policies. Correct MIME type configuration is essential for proper website operation.
