Nowadays, more and more people are working on their computers with different images. One of the most popular formats is PNG. It differs from other image formats by the ability to save large graphic files without loss of quality and support for transparency.
But one of its main disadvantages is the large file size. Appendix ImageAlpha designed to solve this problem for Mac users.
Program ImageAlpha allows users to reduce the size of PNG-file by transcode the file from 24-bit to 8-bit color and a decrease in range. Most often, this will have a minimal effect on image quality, but will save space on your computer's hard drive or make website pages with your image load faster. 8-bit compatible with all web browsers, iOS and Android.
When adding a new image to the program window using the slider, you can adjust the number of colors in the image. If the image is of sufficient quality, the effect will not be very noticeable, and the file size will decrease.
You can also choose a mechanism for image compression: Median Cut, NeuQuant, Blurizer, Posterizer. Below you can see the original image and processed with the help of compression algorithms kgo copies, while the color depth was reduced from 256 to 16. This made the file size 90% smaller.
All changes to files can be compared with the original. To do this, you can press the spacebar at any time.
You can download ImageAlpha for free from the developer's website.
