HTTP Content-Type Parser
Parse MIME types, media types, charsets, boundaries and other Content-Type parameters instantly in your browser.
How to Use
Enter or paste an HTTP Content-Type header string (e.g. application/json; charset=utf-8).
Inspect the parsed primary type, subtype, structured syntax suffix, and extracted parameters.
Check the compression guidance to verify whether gzip or Brotli encoding is recommended.
Copy the normalized MIME type string or structured JSON representation for API development.
Why Use HTTP Content-Type Parser?
RFC-Compliant Parameter Parsing
Accurately separates media types and parameter pairs while handling quoted strings and boundary markers.
Compression Guidance
Recommends whether enabling gzip/Brotli transfer encoding reduces payload size or wastes CPU.
Security Context & Best Practices
Highlights XSS sensitivities (HTML/SVG), JSON parse hazards, and MIME sniffing prevention.
Structured Suffix Recognition
Detects XML (+xml) and JSON (+json) suffixes in custom vendor media types.
About This Tool
The HTTP Content-Type Parser breaks down complex MIME type headers into their primary type, subtype, structured suffix, and parameter key-value pairs according to RFC 2045 and RFC 7231. It includes an integrated database of common MIME types, recommended HTTP compression strategies, and security considerations.
