MIME Type Lookup – Free Online Tool | Trencada

MIME Type Lookup – Find MIME Types & File Extensions Instantly

Setting a Content-Type header, writing an accept attribute, or configuring your server? You need the right MIME type. Trencada's MIME Type Lookup works both ways: type a file extension (or even a full filename like song.mp3) to get its MIME type, or type a MIME type (like audio/mpeg) to see all its extensions. The direction is detected automatically — no mode to pick. With 90+ common MIME types covering images, fonts, audio, video, documents, and web files, plus one-click copy for headers and configs. No signup needed — everything runs locally in your browser.

How to Use the MIME Type Lookup

1. Type an extension, filename, or MIME type. Enter something like .woff2, photo.png, or image/png in the lookup box.
2. Or tap a quick pick. Use the 6 shortcut chips (.png, .svg, .woff2, image/jpeg, application/pdf, video/mp4) for instant common lookups.
3. Click "Look up". The direction is detected automatically — you'll see the MIME type (or the matching extensions), its category, and all associated extensions. Use "Reset" to clear.
4. Copy the result. Click "Copy result" and paste it into your HTTP headers, HTML, or server configuration.

Frequently Asked Questions

What is a MIME type?

A MIME type (like image/png or application/pdf) tells browsers and servers what kind of data a file contains, so it can be handled correctly — displayed, downloaded, or played.

Is the MIME Type Lookup free?

Yes — it's completely free with unlimited lookups and no signup required.

Can I look up a MIME type from an extension and vice versa?

Yes. Type an extension (or filename) to get its MIME type, or type a MIME type to see all its file extensions. The tool detects which direction you need automatically.

Are my lookups sent anywhere?

No. The full MIME database is built into the page and every lookup runs locally in your browser. Nothing is uploaded or stored by Trencada.

How many MIME types are covered?

The built-in database covers 90+ common MIME types across images, fonts, audio, video, documents, archives, and web files — including modern formats like WebP, AVIF, WOFF2, and WebM.
