A jpg does however allow you to create smaller file size than you could with a png. Png also handles detailed high contrast.
Jpgs tend to be smaller but they use lossy compression meaning that each time you save them you lose some quality.
Png vs jpeg image quality. Png is a good choice for storing line drawings text and iconic graphics at a small file size. Jpg is a common choice for use on the web because it is compressed. The reason is because the compression is lossy which means that certain unnecessary information is permanently deleted.
Pngs are larger but there s no loss of quality. The difference between jpg and png is the algorithm they use to compress images. The biggest advantage of png over jpeg is that the compression is lossless meaning there is no loss in quality each time it is opened and saved again.
Jpg format is a lossy compressed file format. For storing line drawings text and iconic graphics at a smaller file size gif or png are better choices because they are lossless. This makes it useful for storing photographs at a smaller size than a bmp.
Some quality is compromised when an image is converted to a jpg.
