Frequently Asked Questions
What is a MIME type?
MIME (Multipurpose Internet Mail Extensions) types identify file formats on the internet. They consist of a type and subtype, like text/html or image/png.
Why do MIME types matter?
Servers use MIME types in Content-Type headers to tell browsers how to handle files. Wrong MIME types can cause files to download instead of display.
