How to compress PNG images with PNGGauntlet

PNG images tend to be larger in file size than JPEGs. PNGGauntlet can help reduce the PNG file size so they load faster and take up less storage.


PNG, a lossless image format, works well for text and graphics, like screenshots. The one drawback to PNG is that the resulting file size can be larger than JPEG files. PNGGauntlet, a free Windows program, can help reduce the size of PNG files and since PNG is lossless, compressing it will have no impact on its quality.

To use PNGGauntlet, first make sure you have Microsoft .NET framework 4.0 installed. When you're ready to start, add the PNG files you want to compress by dragging them over to the screen or clicking on the Add Images button. Next, select the Output Directory, then click the Optimize! button.
