JPG vs PNG
JPG is usually practical for photographs and smaller files, while PNG uses lossless encoding and can support transparency. Converting a JPG to PNG does not restore detail that was already lost in the JPG. See JPG vs PNG: Which Format Should You Use? for a format comparison.
Need smaller files?
PNG output can be larger than the original JPG because PNG is lossless. If your goal is a smaller image file, use the Image Compressor instead. If you also need exact pixel dimensions, use the Image Resizer.
