Applies compression to the image, reducing file size. Accepts any number from 1-100. If not specified, the default is 75.

The quality parameter can be added to the querystring as either q or quality

The best results for quality and file size can be found around 40-60%, where we’ve found generated images to be visually indistinguishable from the source image.

The original image and all quality variations below are 2048 × 1024 pixels.
