Frequently asked questions
What is a MIME type?
A MIME type (media type) tells a browser or client how to interpret a file, such as text/html or image/webp.
Why does mine serve the wrong type?
Server configuration decides the Content-Type. Checking it with our SSL/redirect tool shows what your server actually sends.
Does it cover every format?
It covers the extensions most sites use day to day; obscure formats may be missing.
