What it does
Look up the correct Content-Type for any file extension (or the other way round). Covers images, fonts, video, audio, JSON, common office formats, and rarer ones like .webmanifest and .avif. Useful when debugging upload handlers or configuring nginx/Apache content-type rules.
For HTTP status codes use HTTP status code lookup. For image conversion, image format converter. For clean filenames, filename cleaner.
