PNGExtra – App Details

More details about the PNGExtra app

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.

Writing The App

PNGExtra App History

Following the success of my JPGExtra App for optimizing JPG files, I once again set out to write an app that would similarly remove "extras" from PNG files.

Luckily, the PNG file format is fairly clear about what is "critical" and what are "extras", so the app was a little easier to write. I still encountered some surprises during my testing (eg. on transparent files). I've tested it on hundreds of PNG files, including a large number of deliberately corrupt files. This ensured that PNGExtra ran 100% reliably, that it handled corrupt files as well as some "weird" formats, and that the resultant optimized PNG files were all written correctly and viewed identically to the originals. I'm confident that PNGExtra will handle just about anything that is thrown at it.

First Impressions of PNGExtra

Compared to other pretty apps with nice colourful icons and cute animations, PNGExtra is like watching an old black and white movie!

I'm not sure that this app will ever be considered an "old classic" like some of those movies, probably more like a good workhorse.

PNGExtra Contains No "Extras"

I programmed PNGExtra with a "minimalist" philosophy: It's the absolute minimum app that will do the job. It doesn't include an image viewer. It doesn't edit images. It doesn't catalogue images. It doesn't upload to websites. In short, it doesn't contain ANYTHING that you probably already have in other image or website software. It doesn't even contain full-colour icons, as these would have almost doubled the size of this tiny app!

PNGExtra does only ONE thing: It removes "extras" from PNG files, very quickly and very reliably. You can fire up PNGExtra in a split second, process any number of files with one or two mouse clicks, and your job is done. I like it that way.

PNGExtra Contains No Hidden Surprises

A lot of today's software contains "hidden surprises". Some apps cause problems, either because of modifying your system or performing tasks in a non-standard manner. Other apps do questionable things, such as "phoning home" with your private details. Rest assured that PNGExtra contains no such hidden surprises!

The End Result

Besides creating the smallest, fastest, most efficient PNG files, the PNGExtra app is itself an example of optimization. I believe it's the smallest, fastest, most efficient PNG file optimization app available.
