Does BMP to JPG lose much quality?

At 85-90% quality, the difference is almost invisible to the naked eye. BMP to JPG is lossy compression, but for photos and screenshots, the advantage of reducing size by over 90% far outweighs the slight quality loss.

How much smaller can BMP to JPG files be?

BMP uses no compression. A 6MB BMP converted to JPG (90% quality) is usually only 200-500KB, a reduction of over 90%.

Does BMP to JPG support transparent background?

Neither BMP nor JPG supports transparent backgrounds, so the conversion does not involve an alpha channel. The background remains unchanged.
