MIME Type Reference & Lookup

MIME types (Multipurpose Internet Mail Extensions) are standardised identifiers used to indicate the nature and format of a document, file, or byte stream on the internet. First introduced for email attachments, they are now essential for web servers, browsers, and APIs. A MIME type has two parts: a type (like image, text, or application) and a subtype (like png, html, or pdf), separated by a slash.

1. Browse by Category: Click any category chip (Application, Audio, Image, etc.) to filter MIME types by top-level type. Each chip shows the count of entries in that category. Click again to deselect and see all types.
2. Search Any Field: Type in the search box to filter across MIME type (e.g. image/svg), file extension (e.g. .svg), name (e.g. "Scalable Vector"), or description. The search is case-insensitive and narrows results as you type.
3. Review Details: Each result card shows the full MIME type in monospace, the common name in bold, a human-readable description, and associated file extension tags. The card is colour-coded by category for quick scanning.
4. Copy to Clipboard: Hover over any card and click the copy icon to copy the MIME type string. A confirmation toast appears at the bottom of the screen.

• Application: Binary or structured data formats like PDFs, Word documents, JSON, XML, ZIP archives, executables, and proprietary formats. The largest category covering both documents and software data.
• Audio: Sound and music file formats including MP3, AAC, FLAC, OGG, WAV, WMA, and MIDI. Both lossy and lossless compression codecs.
• Image: Still image formats including JPEG, PNG, GIF, WebP, SVG, AVIF, HEIC, TIFF, BMP, camera RAW formats (CR2, NEF, ARW), and Photoshop PSD files.
• Text: Human-readable text formats including HTML, CSS, JavaScript, Markdown, CSV, YAML, SQL, and source code files. Also includes calendar and contact data formats like iCalendar and vCard.
• Video: Digital video formats including MP4, WebM, AVI, MKV, MOV, WMV, Flash Video, Ogg Video, and 3GPP mobile formats. Also includes codec-specific types for H.264, H.265, VP8, and VP9.
• Multipart & Message: Email-specific types for MIME multipart bodies (mixed, alternative, related) and message formats (RFC 822 email, delivery status, HTTP messages). Essential for email systems.
• Font: Digital font formats including TrueType (TTF), OpenType (OTF), Web Open Font Format (WOFF/WOFF2), and TrueType Collections.
• Model: 3D model formats including OBJ, STL, glTF, GLB, U3D, VRML/X3D, IGES, and 3MF. Used in 3D printing, CAD, and 3D graphics.

The MIME type database in this reference is compiled from the official IANA (Internet Assigned Numbers Authority) registry, common usage in web servers (Apache, Nginx), and well-established industry conventions. While we strive for completeness and accuracy, MIME types evolve over time as new formats are standardised and old ones are deprecated. Always consult the latest IANA registry for authoritative MIME type assignments. This reference runs entirely in your browser with no server requests - the complete database is bundled in the page and does not require internet access to use.
