I want disable some Image Formats (Without Plugin)

[factstea]

Hi, Team

I am running a website over wordpress while using MagazineNP Theme. My website is accepting JPG, PNG and all other image formats. But I want enable only Webp format. How Can i do that without plugin?

I have added a code in additional CSS ::
==================================================
add_filter(‘upload_mimes’,’restrict_mime’);
function restrict_mime($mimes) {
$mimes = array(
‘webp’ => ‘image/webp’,
);
return $mimes;
}
==================================================
But it dosent work. Please help me out in this. I want enable webp format only for images. Whenever anyone try to upload anyother fotmat image then should not be done and he should see a massage something like, You can upload webp only or only webp is supported.

I do not want make changes in docs like pdf, wordfile or etc. I want change in Image format only.

Thanks
FactsTea !!
