WebP Compression Rate
Generated images are saved to the device; this setting determines the image compression rate used during that process.
Settings
Configure this via the Developer Mode settings screen / Developer Options. The default is set to 0.9, prioritizing file size. You can select 1.0 for high-quality saving.
Notes
If you simply want the highest possible image quality, it is more reliable to enable the save flag in the image generation parameters and save the images directly on the PC performing the generation. However, please note that doing so will remove the link between the images and the save data.
