About the MIME type lookup

Handytool's MIME type lookup helps you find the right Content-Type header for any file — whether you're configuring a web server, building an API, or filtering an upload form. Search by extension (.png, .pdf, .epub) or by media type (image/png, application/pdf), and filter by group. Each entry includes the canonical IANA-registered MIME type, the file extensions that commonly use it, and a one-line description.

MIME type lookup features

  • 01

    Search by extension or MIME

    Type .webp or webp to find image/webp; type pdf or application/pdf to find the document type; type "font" to see all font media types.

  • 02

    Group filter

    Narrow results to image, video, audio, text, application, or font when you only care about a particular family of files.

  • 03

    Real-world coverage

    Includes the formats developers actually deal with — Office Open XML (docx, xlsx), modern image formats (avif, heic), and lesser-known ones like FB2, EPUB, and WebAssembly.

MIME type lookup FAQ

Why are some extensions mapped to several MIME types?
A single extension can be used by multiple legitimate types — for example .xml is both text/xml and application/xml. Use whichever matches the way your tooling expects to consume the file.
What's the difference between application/octet-stream and a specific type?
application/octet-stream is the fallback for arbitrary binary data when no specific type is known. Browsers usually prompt to download such responses. Use a specific type whenever you can — it enables in-browser preview and correct handling.
Is heic actually image/heic or image/heif?
Both exist — image/heic refers to HEIF files using the HEVC codec (the most common case on iPhones), while image/heif is the more general container type. Most servers use image/heic for .heic uploads.
Are font/woff and application/font-woff the same?
font/woff is the modern, IANA-registered type. The older application/font-woff is still seen in legacy configs but should be migrated.
