JPEG vs. BMP
JPEG uses lossy compression and is efficient for photographs. BMP stores bitmap pixels in a simple format commonly supported by Windows and legacy software.
Converting creates a new BMP file from the decoded JPEG image. BMP output is usually larger, but useful when a workflow requires it.
