MIME types tell browsers what kind of file the server is sending. If a MIME type is missing or wrong, a file may download instead of display, fail to load as a font, or be blocked by the browser.

What MIME types do

A MIME type pairs a file extension with a content type, such as .webp with image/webp or .json with application/json. Most common types are already configured by the server, so only add custom entries when a file type is not being handled correctly.

Add a MIME type in cPanel

Log in to cPanel.
Open Advanced and choose MIME Types.
Enter the MIME type, such as image/webp.
Enter the extension without a dot, such as webp.
Click Add.

Common examples

Extension	MIME type	Use
`webp`	`image/webp`	Modern image format.
`woff2`	`font/woff2`	Web fonts.
`svg`	`image/svg+xml`	SVG images.
`json`	`application/json`	API and app data.
`mp4`	`video/mp4`	Video files.

Set MIME types in .htaccess

If the cPanel MIME Types tool is not available, add entries to the site's .htaccess file:

AddType image/webp .webp
AddType font/woff2 .woff2
AddType image/svg+xml .svg
AddType application/json .json

Troubleshooting

Clear browser and CDN cache after adding a MIME type.
Check the browser developer tools Network tab to confirm the Content-Type response header.
Remove duplicate or conflicting AddType rules from nested .htaccess files.
If a 500 error appears after editing .htaccess, revert the last change and check cPanel error logs.
