Use TinyPNG with WordPress to Automatically Compress PNG FilesĬompress PNG for WP is a new plugin created by the folks at Gecko Designs. The files produced by the service are supported everywhere, including all major browsers, even as far back as IE 6, and on mobile devices.

It uses a technique called “quantisation” that combines similar colors and converts the file to a much smaller 8-bit indexed image. It provides advanced lossy compression for PNG images that preserves full alpha transparency and is virtually invisible.Īlthough it’s very difficult to see with the naked eye, TinyPNG provides more than 70% reduction in file size here. That’s where the TinyPNG web service comes in handy for compressing PNG images. PNGs can also handle more color than JPGs and are sometimes a better choice for using with highly colorful, complex images.Īlthough WordPress has built in compression for JPG images, there is nothing in the core to handle PNG compression.

However, there are certain situations where using a PNG might be preferable, such as when you need lossless compression of larger images or want to maintain alpha transparency. PNG image files can be bulky and often have file sizes 5-10 times larger than JPG images.
