You probably won’t run into these issues if you’re saving small images for use on the internet, but keep it in mind when working with large photos.
I’ve even crashed editing programs while experimenting with large-scale PNG exports! However, if you’re saving a large high-resolution photo, PNG files can seriously slow down your computer during the saving process, especially when you’re using the highest compression setting. PNG is great for this type of small-scale application where image quality is essential even through wide color areas. Lossless compression and transparency are great features, but PNG isn’t always the best format to use.Īs you might guess from the name, PNG is often used in web design thanks to small file sizes and the design flexibility that you get with transparent images.

PNG stands for Portable Network Graphics, and the format was created in the early days of the internet before the JPEG format reigned supreme in the world of digital imagery. Higher compression levels simply mean that the computer will take longer to save the file, telling it to dedicate more time to compressing it into the smallest size possible. Unlike the compression method in JPG files, PNG uses lossless compression so your image always looks perfect. 9 is the highest setting and 0 is the lowest setting, but your images are always perfectly compressed. Interlacing is useful for images on mobile websites because interlaced PNGs begin to display even before being fully downloaded on slow mobile internet connections, but otherwise can be disabled.Ĭompression level plays an important role when saving your PNG images to the smallest possible file size, which is also useful in mobile web design (and many other places). The more important settings are Interlacing (Adam7) and Compression level.

Like TIFF files, the PNG format is capable of handling 16-bit images and that presents some unique byte order configurations that most users won’t need to use. You’re also better off leaving the pixel format set to automatic. You might be able to shave off a few bytes by skipping the data, but it won’t make a huge difference. Most of the PNG save options relate to metadata standards, such as EXIF, XMP, and IPTC, but they’re pretty self-explanatory and they don’t affect your image quality at all.
