Will I lose quality converting JPG to JXL?▼

Both JPG and JXL use lossy compression. There may be minimal quality loss during conversion, but at high quality settings (85-95%), the difference is virtually imperceptible to the human eye.

Will my JXL file have transparency?▼

JXL supports transparency, but since JPG does not include alpha channel data, the converted file will not have transparent areas. You would need a JPG file with transparency data to take advantage of this feature.
