Only JPG File converts what to do for PNG Images

Hi @loanpaye –

You can use the webp_uploads_upload_image_mime_transforms filter to add additional mime transforms.

Something like:

add_filter( webp_uploads_upload_image_mime_transforms function( $transforms ) { 
    $transforms['image/png'] = 'image/webp';
    return $transforms;
} );

The above code doesn’t work, I tried to fix it but it still doesn’t work

add_filter('webp_uploads_upload_image_mime_transforms', function($transforms) {
$transforms['image/png'] = 'image/webp';
return $transforms;
});

And what about those images which is already present in site or server

They also automatically generated into webp

Meanwhile i am talking here if some images are already i uploaded and than after that i installed this plugin so this plugin may convert already uploaded images into webp or i need to upload them again

And also tell me where to place this code

add_filter( webp_uploads_upload_image_mime_transforms function( $transforms ) { $transforms[‘image/png’] = ‘image/webp’; return $transforms; } );

@loanpaye Can you try the below. Regarding where to place this, you can insert into a custom functions plugin or a child themes functions.php file.

function webp( $transforms ) {
$transforms['image/png'] = array( 'image/png','image/webp');
return $transforms;
}
add_filter( 'webp_uploads_upload_image_mime_transforms', 'webp' );

In relation to existing images, there is an open GitHub issue to provide this functionality which is currently being worked on. Feel free to subscribe to that issue for updates. If you prefer not to wait, I believe there are some third party plugins out there which can provide that functionality.
