PNGExtra - Program Details
More details about the PNGExtra program 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.

Writing The Program
PNGExtra Program History:
Following the success of my JPGExtra Program for optimizing JPG files, I once again set out to write a program 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 program 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.

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

I'm not sure that this program 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 program 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 web-sites. In short, it doesn't contain anything that you probably already have in other image or web-site software. It doesn't even contain full-colour icons, as these would have almost doubled the size of this tiny program!

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 programs cause problems, either because of modifying your system or performing tasks in a non-standard manner. Other programs do questionable things, such as "phoning home" with your private details. Rest assured that PNGExtra contains no such hidden surprises!
No Spying | No Ads | No Trojans | No Phoning | NO Worries!
Ian Fieggen, programmer of PNGExtra The End Result:
Besides creating the smallest, fastest, most efficient PNG files, the PNGExtra program is itself an example of optimization. I believe it's the smallest, fastest, most efficient PNG file optimization program available.
