Advanced users can force the quality of JPEG images to a discrete "q" value between 25 and 100 using this setting <br />
For example, forcing the quality to 60 or 70 might yield greater savings, but the resulting quality might be affected, depending on the image. <br />
We therefore recommend keeping the <strong>Intelligent Lossy</strong> setting, which will not allow a resulting image of unacceptable quality.<br />
This setting will be ignored when using the <strong>lossless</strong> optimization mode.

Advanced users can also set the resolution at which colour is encoded for JPEG images. In short, the default setting of <strong>4:2:0</strong> is suitable for most images,<br />
and will result in the lowest possible optimized file size. Images containing high contrast text or bright red areas on flat backgrounds might benefit from disabling chroma subsampling<br />
(by setting it to <strong>4:4:4</strong>). More information can be found in our <a href="https://kraken.io/docs/chroma-subsampling" target="_blank">documentation</a>.
