WebP Compression Ratio
Generated images are saved on the device, and this setting configures the image compression ratio used when saving.
Settings
Configure from the Developer Mode Settings Screen / Developer Options. The default is 0.9, a value that prioritizes file size. Here you can select 1.0 for high-quality saving.
info
Simply in terms of image quality, it's more reliable to enable the save flag in the image generation parameters and save on the PC where images are being generated. However, the association with save data will be lost.
