media library - Set different max upload size limits based on file typeextension

When uploading with video files to the Media Library, it's apparent that you need to increase the Max upload file size value. But this will be applied to all media types, including images and documents.

Is there any way or simple code that can set different size limits based on the file type/extension so that I can grant a large limit for videos, a small limit for images, and a different limit for documents?

I think WordPress should handle this natively because it's not logical to have the same limit for all file types. This was OK in the past when WordPress saw the light for the first time, but not in the current time.

• 1 There are already some good questions with answers that ask about restricting the dimensions and file size of images on the site, but recommendations are off topic here, asking for a plugin will get your question closed and shut down – Tom J Nowell ♦ Commented Sep 15, 2020 at 11:37
• I'm asking for a way to have multiple limits for the Max upload file size field based on the uploaded file extension. Thank you@TomJNowell. – Jaafar Abazid Commented Sep 15, 2020 at 13:54

This should work:

function max_video_size( $file ) {
  $size = $file['size'];
  $size = $size / 1024;
  $type = $file['type'];
  $is_image = strpos( $type, 'video' ) !== false;
  $limit = 750;
  $limit_output = '750kb';
  if ( $is_image && $size > $limit ) {
    $file['error'] = 'Video files must be smaller than ' . $limit_output;
  }
  return $file;
}
add_filter( 'wp_handle_upload_prefilter', 'max_video_size' );

Rinse and repeat, changing video in the $is_image line to whatever filetype you want to specify, and even by altering the function, building all desired filetypes into the one filter.
