Why convert JPG to PNG?
PNG is lossless, so it is the safer format for editing, screenshots, logos and graphics that get saved many times. Converting a JPG to PNG will not restore detail lost earlier, but it stops further quality loss. Note that PNG files are usually larger than JPG.
| Format | Compression | Transparency | Compatibility |
