What this tool does

Look up the Content-Type while writing an upload endpoint or a static server config: type an extension such as png, .svg or mp4 and get the standard MIME type without digging through server configuration files.
Go the other way too: paste a Content-Type string (say application/vnd.openxmlformats-officedocument.wordprocessingml.document) to find out which suffix to save the file with.
Browse by category: when picking a sensible image or archive format, filter to Image or Archive to see the whole family with its Chinese and English descriptions at once.
Rely on fuzzy search when the spelling is uncertain: typing "word" lists every type containing word, and "text" lists the whole text/* family.

Example

Input

image/svg+xml

Output

image/svg+xml
Extensions: .svg, .svgz
Category: Image
English: SVG vector image

A query containing a slash is matched against MIME types exactly; anything missing from the table falls back to substring matching and may return several rows.

Frequently asked questions

What is the difference between a query with and without a slash?

A slash means "match the MIME type" (parameters such as ; charset=... are ignored); without a slash the query is matched against extensions, where the leading dot is optional and case does not matter. Both try an exact match first and fall back to substring matching.

Is this mapping table authoritative?

It is a hand-curated set of 195 common types covering text, images, media, fonts, archives, documents and scripts. The IANA registry is larger and authoritative — for anything missing here, trust IANA or the actual server behaviour.

Why do some entries have no extension?

Types such as text/event-stream and multipart/form-data never map to a file suffix, so the entry shows "No standard extension". That is expected rather than missing data.

What if a search returns nothing?

Check the spelling and try a shorter fragment, for example "svg" instead of "image/svg+xm". Queries of one character rarely match anything, so also switch the category filter back to All categories.

Is my search sent to a server?

No. The whole table is a JavaScript array inside the page and the lookup happens in memory, with no network request, so it also works offline.
