Why Are BMP Files So Large?
BMP stores image data with little or no compression, so the files are large. PNG compresses the same pixels without losing any detail, which normally makes a much smaller file with identical quality. JPG is smaller still but discards some detail.
PNG or JPG?
| Choose | When |
|---|---|
| PNG | Screenshots, graphics, text, or any image where you want zero quality loss |
| JPG | Photographs where a small file matters more than exact pixels |
