Optimization tip #1 - scale images to their display size

0:24	Resizing images to their display size can reduce the bandwidth required to deliver them. Use Cloudinary's c_scale parameter, together with a width or height, to scale an image to its display size. You can also automate resizing by taking advantage of Cloudinary's support for responsive design.

Optimization tip #2 - automate quality

0:56	Use Cloudinary's quality parameter with a value of auto q_auto, a smart algorithm that reduces the size of your images while retaining their visual quality. If a quality parameter is not applied in your URL, Cloudinary uses a default setting, Default image quality, which can be modified in Cloudinary Console under Settings > Optimization.

Optimization tip #3 - auto select file format

1:39	Use Cloudinary's fetch format parameter with a value of auto f_auto to automatically detect which browser is requesting the image so that it may select and deliver the image in its most efficient format.

Optimization tip #4 - change format to reduce file size

2:07	You can use the lossy flag fl_lossy to convert images from PNG to JPEG if the alpha channel is not being used, to reduce the file size.

More optimizations

2:47	You can get more optimizations and insights based on your usage patterns by going to the Reports page in your Cloudinary Console.
