Conversion complete? Your AVIF files are saved to the destination folder, ready to use.
How KML and AVIF differ in practice
KML describes geometry rather than pixels, so it has no inherent resolution. The conversion renders it at whatever size you choose, and that choice is final: enlarging the AVIF afterwards will not recover the sharpness. Set the output dimensions or DPI before converting, not after.
