What happens to your image going from JPG to PNG
- A PNG can't restore detail the JPG had already dropped, but it does prevent any more loss when you re-save. The file will be larger, because PNG keeps every pixel exactly.
JPG vs PNG in brief
- JPG (or JPEG) is the photo format that works almost everywhere. Lossy compression keeps files small, but there's no transparency and each re-save throws away a little more detail.
- PNG is lossless, meaning every pixel is stored exactly, and it supports full transparency. That suits screenshots, logos and graphics perfectly, but a photo saved as PNG is often several times larger than the same shot as a JPG.
Mac tips
- macOS has its own shortcut as well: select images in Finder, right-click › Quick Actions › Convert Image (macOS 12 or newer) to get JPEG, PNG or HEIF. It can't output WebP and doesn't preview the quality.
- It runs the same on Apple silicon and Intel Macs, with nothing to get from the App Store.
