PNGExtra App

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.

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.

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.

PNGExtra Details

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

Get PNGExtra

PNGExtra is an incredibly tiny app, so it should only take a split-second to download onto your computer. Best of all, it's free!
