How to migrate correctly to ShortPixel Image Optimizer
If you have been using another image optimization plugin, before installing ShortPixel Image Optimizer you need to follow a few steps. These change, though, depending on what you want.
I want ShortPixel to re-optimize my images
If you want SPIO to optimize your whole media library, which was already optimized with another image compression plugin, you need to make sure you restore the backups of your images. Each plugin does it in a different way, so you need to find out how to do that. If you don't restore the backups, then ShortPixel will optimize your already compressed images, which can lead to over-optimizing.
- Before uninstalling the old image optimization plugin, restore your original images.
- Uninstall the old image optimization plugin.
- Install ShortPixel Image Optimizer.
- Start optimizing :-)
I want to preserve the optimization of my images
In this case, you don't need to do anything special. Uninstall your previous image compression plugin, install SPIO and just make sure not to use the Bulk ShortPixel option (under the Media menu) because that's going to optimize your whole media library, even the old files.
Now, to optimize the newly updated files:
- Go to Settings > ShortPixel > Advanced.
- Make sure you have enabled Optimize media on upload
I'm already using SPIO and I want to start using ShortPixel Adaptive Images (SPAI), do I need to do anything special?
