Quality
Quality
Parameter: quality
Units: Number
Range: 0 to 100
Default: 85
Dictates the compression ratio of the output image. The higher the number the more compressed the image will be. Lower quality significantly reduces the image size but also results in worse overall quality and artificing if you push it too far (as seen on the third image).
?quality=80 (results in a 117KB image)
?quality=50 (results in a 81KB image)
?quality=10 (results in a 35KB image)
Default quality
If you do not specify quality in query parameters, there are two possible default values.
Smart Image Optimization option
If you go to Optimizer -> Settings in your Pull Zone you can set Smart Image Optimization parameters. This parameter will then dictate the quality for users request. In the example below, desktop requests would get a default quality of 80.
Default in nothing set
In case where the Smart Image Optimization is not set nor was there a quality query parameter sent in your request, the quality will be set to 85.
Quality set in query parameter has the highest priority, then the Smart Optimization setting, then the general default.
