- Screenshots with sharp text
- Images you will edit many times

JPG removes tiny details most people cannot see, so files get much smaller.
That is why phone cameras save photos as JPG. Use it for:

- Uploading to government portals
- Website photos that must load fast
One limit: JPG has no transparency. A transparent PNG logo turns white behind when saved as JPG. To remove a white background, use JPG to PNG.
