How it works
STEP 1
Type what you have
Enter a file extension (like "webp" or ".tar.gz") or a content type (like "application/json"). It works both ways — search matches extensions and MIME types as you type.
STEP 2
Read the matches
Each result shows the extension and its MIME type. When you search by MIME type, every extension that maps to it is listed together.
STEP 3
Copy what you need
Click the copy button on any row to copy the MIME type, or copy a whole HTTP Content-Type header ready to paste into your code or server config.
