Generate Random MIME Type

Free Random MIME Type Generator

This tool produces results like application/vnd.oftn.l10n+json, image/ief, and application/x-hdf, giving you credible test values across a wide range of content categories.

You can generate up to 1000 MIME types at once and export them as CSV, Excel, or HTML files, or copy the values directly to your clipboard for easy integration into your workflow.

Each MIME type is randomly selected from valid-looking structures, closely resembling those used in HTTP headers, file uploads, and media-type validation systems.
