Show Guide

MIME Types (Multipurpose Internet Mail Extensions) are used by web servers and browsers to determine how to process a file. The correct MIME type ensures that your website's assets are rendered correctly.

Why does it matter?

Browser Rendering: If a CSS file is sent with text/plain, the browser will ignore the styles.
Downloads: MIME types control whether a file opens in the browser or prompts a 'Save As' dialog.
Security: Correct content-typing helps prevent MIME-sniffing attacks.
