You can use ShortPixel and NitroPack simultaneously, but you have to disable ShortPixel's WebP conversion. Our service converts images to WebP by default, so ShortPixel's WebP conversion must be disabled to avoid compatibility issues.
- In your WordPress admin panel, please go to Plugins, find ShortPixel Image Optimizer, and click on Settings.
- Go to Advanced, find the setting WebP Images, and disable it.
- Save any changes, and purge your NitroPack cache.
