The last fields are also important, and we advice you to pay attention to them. At first, you can choose a folder to exclude from optimization.

The last field is for setting the location of your backups. If you don’t select a folder, you will not be able to restore the originals if the compressed images don’t suit your needs or taste.

We recommend you to choose the folder where your images are stored. ShortPixel will create a backup folder there called ShortPixelBackups. This way, you can restore your images by simply copying the originals back in Your Images folder.
