Take a look at this example. The image in the example below has undergone the Filestack resize and compress tasks. The original version of the image is 1.42 MB and is formatted as a JPEG. When Filestack image conversion parameters are applied to the image, it is shrunk down to 48.45 KB without diminishing the quality of the image.


JPEG 48.45 KB

With Filestack’s auto_image task, the same image is delivered as a WebP format and is even more significantly reduced in size.



WebP 44.84 KB
