Yes, there is an option to restore all/individual images. Please be sure to restore your images before uninstalling the app.
1. Restore All Images in Bulk
1.1 Open Image Optimizer and click Settings.
1.2 Click the Restore All Images.
Useful Tips: If you are not happy with Lossy image optimization we recommend changing the default compression method to Lossless and reoptimize all images instead of restoring them. Images will not lose any quality, they will be 100% same as the original.
2. Restore Individual Images
2.1 Open Image Optimizer, navigate to your Optimization History, click the Details.
2.2 Click the Restore button.
