How to Convert PNG Images to JPG on Android: 3 Ways

Two of the most popular formats of images are PNG and JPG. The main difference between these two is the compression algorithm they use. PNG is a lossless format, whereas, JPG is a lossy format that offers a higher compression rate than PNG.

In lossless compression, the quality of the image is not affected and the original data can be recovered when the file is uncompressed. On the other hand, lossy compression will permanently delete some very small details of the image and thus it affects the quality.

Note that, JPG and JPEG are the same image formats and they are interchangeable. JPG images are normally smaller in file size as compared to the PNG images. However, the advantage of the PNG format is that it can store transparent background images also.

Sometimes, you want to convert PNG format images to JPG. For example, if you want to upload an image somewhere on the internet but you are not allowed to select PNG files there. You may also need JPG images for editing purpose.
