About Mimechord

Mimechord indexes 2512 media types from the IANA registry (mirrored via the MIT-licensed mime-db package, which republishes IANA's own CSVs) and explains the 99 that people actually search for — each with its defining spec rendered as a citation, and 34 of them with verified magic-byte signatures.

Registry facts (extensions, charset, registration status) come straight from the package at build time — never transcribed, so they can't drift. The prose is entirely our own. A type we haven't explained yet still appears in its category index, honestly marked; the registry is never pretended smaller than it is.

The file sniffer reads a file's first bytes locally in your tab and matches them against the same signature data the type pages cite. Nothing uploads, ever — there is no server to upload to.

Mimechord is part of a small network of reference sites built with the same conviction: one honest page for the thing you actually searched for.
