Woocommerce Cropped Image such as:

So how can I fix this problem, like the original image, stop cropping for thumbnails resized by WooCommerce?

Then at the bottom of the page, in "Product Images, disable Hard Crop options and save changes:

Then you will need to regenerate your products images with Regenerate Thumbnails plugin:

• Install and activate Regenerate Thumbnails plugin.
• Going In Tools menu you will find a "Regenerate thumbnails" item page.

WITH PHP ALTERNATIVE:

Sometimes in some themes, this is settings are hard coded. So you can change them with this code snippet, pasting it in the function.php file of your active child theme or theme:

function yourtheme_woocommerce_image_dimensions() {
    global $pagenow;

    if ( ! isset( $_GET['activated'] ) || $pagenow != 'themes.php' ) {
        return;
    }
    $catalog = array(
        'width'     => '300',   // px
        'height'    => '300',   // px
        'crop'      => 0 // Disabling Hard crop option.
    );
    $single = array(
        'width'     => '150',   // px
        'height'    => '150',   // px
        'crop'      => 0 // Disabling Hard crop option.
    );
    $thumbnail = array(
        'width'     => '90',   // px
        'height'    => '90',   // px
        'crop'      => 0 // Disabling Hard crop option.
    );
    // Image sizes
    update_option( 'shop_catalog_image_size', $catalog );       // Product category thumbs
    update_option( 'shop_single_image_size', $single );      // Single product image
    update_option( 'shop_thumbnail_image_size', $thumbnail );   // Image gallery thumbs
}
add_action( 'after_switch_theme', 'yourtheme_woocommerce_image_dimensions', 1 );

You can comment/uncomment the code (or remove some portions) to feet your needs. This code will overwrite define options in WooCommerce settings > Products > Display (Product Images).

ACTIVATION: You will need to switch your active theme to another and then switch back to activate it.
