What is the difference between luminosity and average?

Luminosity weights RGB channels based on human perception (green most, blue least), producing natural-looking results. Average treats all three channels equally, which can appear slightly flatter.

Can I undo the black and white conversion?

The original color image is never modified. You can re-upload it at any time or simply not save the converted version.

Will the image quality be reduced?

No. The conversion preserves the original resolution and exports as a lossless PNG, so there is no quality loss whatsoever.
