Frequently Asked Questions
JPEG images do not support transparency. When converting a JPG to PNG, the colors are mathematically translated exactly, but the background will remain solid (since JPG files are solid-filled). PNG allows transparency, but cannot create transparent areas out of solid JPG pixels automatically.
