MIME Type Lookup vs IANA Media Types registry
Both let you find the MIME type for a file extension. The IANA Media Types registry is the authoritative source of registered types; Gera Tools' lookup is a fast, searchable map from common extensions to MIME types that runs in your browser.
For the authoritative, canonical media-type registration, use IANA directly. For a quick 'what MIME type does .webp have?' lookup that's extension-first and instant, Gera Tools' lookup is the faster path.
