Large image files will cause your web page to load slowly - especially on mobile devices. This negatively affects the user experience and creates a 'dribble' effect.
Before uploading large image files to the image manager, they should be optimized - compressed in size.
How to optimize an image
Optimizilla is one of the free online tools you can use to compress JPEG and PNG image files.
- Upload your file to Optimizilla.
- Cycle it through twice until your reach -0%
- Download the compressed file and upload it to the image manager.
