PNGExtra Program
Optimize PNG files with no loss of image quality by cleanly removing extras In the same way that my JPGExtra program optimizes JPG files with no loss of image quality, my new PNGExtra program similarly optimizes PNG files by cleanly removing "extras" (or "metadata"). PNGExtra is the world's smallest, fastest and most efficient program for PNG image optimization.

Revealing the extras inside a typical PNG file Sample PNG File
To demonstrate what PNGExtra does and why it's needed, let's look inside a typical PNG file to see the types of "extras" (or "metadata") and how PNGExtra can optimize such files by cleanly removing those extras.
Greater percentage of extras in a typical icon-sized PNG file Sample Icon-sized PNG File
When an image is made smaller, many of the unseen "extras" within the resulting PNG file can still be just as large, constituting a greater percentage of waste. Typical icon-sized PNG files will benefit the most from optimization by PNGExtra.
Typical web page before and after PNG optimization Sample Web Page
Typical websites, particularly shopping and photo sites, contain many individual PNG files on each page. After optimizing those PNG files with PNGExtra, web pages go from "empty" to "full" much faster.

My program for optimizing PNG files is, in itself, an example of optimization. Don't be deceived by PNGExtra's dull, grey appearance because the program is tuned for efficiency and performance.
