Another solution is to use acf/rest/format_value_for_rest/type=image filter

function custom_acf_rest_api_image_format($value, $post_id, $field) {
    // Get the full image object from the ID using wp_get_attachment_image_src()
    $image = wp_get_attachment_image_src($value, 'full');
    // Return an array with the image URL and other metadata
    return array(
        'url' => $image[0],
        'width' => $image[1],
        'height' => $image[2],
        'alt' => get_post_meta($value, '_wp_attachment_image_alt', true)
    );
}

// Hook the filter function to the acf/rest/format_value_for_rest/type=image filter
add_filter('acf/rest/format_value_for_rest/type=image', 'custom_acf_rest_api_image_format', 10, 3);
