Dropified has a built-in image editor (Photopea) that lets you use advanced features similar to PhotoShop to edit your images directly inside of Dropified.
In order to access this tool, you can simply hover over the product image at the bottom of the Product Edit page in Dropified, then click the Advanced Editor icon.
That will open the image editor directly on that page. Edit your image from there using the advanced features. When you're done, click File > Save.
You can move on to the next image to edit and go through the same process, or if you're done, click the green button at the bottom of the Product Edit page in Dropified to Save the changes.
Note: if you need to edit product images within Dropified, then you need to go to the Addon store section of your account to have In-App Photo Editor tool added to your account.
You can watch this video demo to show you how it works:
