Generate Random MIME Type

Generate fake but realistic MIME types to simulate file content identifiers for APIs, headers, upload fields, and development test environments.

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.

These results are great for testing upload restrictions, simulating content negotiation, developing REST APIs, or building frontend interfaces that rely on MIME categorization.

The tool is completely free to use, requires no registration, and delivers instant, ready-to-use MIME types to power your dev and QA processes.
