This compression doesn’t just save you a lot of space you also get a more convenient way of storing them in archives, like compressed folders. The best option to compress your PNG files without affecting image quality is using a program such as WinZip. This delay is usually not a problem unless you have a slow computer or compress thousands of PNG files simultaneously. This compression does not impact image quality like with JPEG it merely optimizes how you store the file on your hard drive.īut exporting your PNG file using more compression takes a longer time. In image editing software, you can often set the amount of lossless compression when saving in PNG. If your website contains many PNG images and you were to reduce their file sizes by only 20%, it adds up, resulting in faster loading times after compression. Coincidentally, file size also impacts loading times on websites. By reducing file size with compression, you can store more images and other files. PNG files are high quality and often take up a lot of space on your hard drive. There are two main reasons as to why someone would want to compress PNG images. It’s better than nothing, but if you’re looking to heavily compress your PNG images, lossy compression or using WinZip are better ways to go. In size, you’re typically looking at a 0-10% reduction. With lossless compression when exporting your image, the file size reduction typically isn’t that great.

Sometimes the difference is noticeable, other times not. But this comes at a loss of image quality, which is why this is called lossy compression. Changing your color depth from 24-bit (16 million colors) to 8-bit (256 colors) can reduce the file size by 50% or more.
