Compression rates

To keep load times fast, Shopify compresses images when they're displayed on your online store. Compressing an image means reducing its file size to allow for faster loading. With compression, more images can be stored in a given amount of disk or memory space. Additionally, the time required to access the images is greatly reduced. Compression might result in a change in image quality, depending on your image's format, size, and original quality.

Shopify's image quality levels after compression are as follows:

• JPEG: Between 65 - 90 percent

• PNG: 90 percent

• GIF: no change in quality

For JPEG images, the quality level of a compressed image depends on the quality of the original JPEG image as well as the output size:
