PNGExtra – Optimize PNG files with no loss of image quality

In the same way that my JPGExtra app optimizes JPG files with no loss of image quality, my PNGExtra app similarly optimizes PNG files by cleanly removing “extras” (or “metadata”). PNGExtra is probably still the world's smallest, fastest and most efficient app 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.
