PngOptimizer 2.4.1
Shrink PNG files without losing image quality

PngOptimizer rewrites PNG files in an efficient way, stripping out any redundant information, hopefully reducing their size without any loss of image quality.

The program really couldn't be much easier to use. Drag and drop your target images onto PngOptimizer and it compresses each one in turn. The new files are saved using the same name and location as the source, while the original files are renamed as a backup (file.png becomes _file.png).

As a bonus, PngOptimizer also supports the import of BMP, TGA and GIF files, also converting these to PNG in much the same way.

Does it work? We gave PNGOptimizer a really tough test, pointing the program at 25 high resolution photos - an average of 8MB each - in PNG format. These took a little while to process, unsurprisingly, but the results weren't bad at all, with our files losing an average of 4% each.

While that may not sound very much, it's still around 320KB per image, certainly enough to be useful. And if you're compressing very small PNGs then the percentage drop can seem much more impressive. We pointed the program at our 50 test PNG web graphics, and it cut their size by 40%, which could noticeably improve web page download times.

If you do have any problems with the compression, or would like the program to work a little differently, then there are some options available. Right-click the PngOptimizer window, select PNG Settings, and you can decide which parts of a PNG file are kept, and which get removed (textual data, background colour, physical pixel dimensions, more).

Verdict:

We would like more control over the output folder and file names (or any control at all, in fact), but otherwise PngOptimizer provides a quick and easy way to reduce the size of most PNG files.

Spotlight: Free Full Software

Unreal Engine 4.8

Free Full Commercial Software

Unreal Engine is Epic Games' game engine, a powerful suite of tools for developing anything from basic 2D games to professional RPGs, first person shooters and whatever else you like.

Wide standards support - DirectX, OpenGL, JavaScript/ WebGL - means your projects can be targeted to almost any platform: consoles, iOS, Android, Windows, OS X, Linux, HTML5 browsers and more.

There's a vast amount to learn, of course, and that's even before you start building your game. But there's plenty of documentation, tutorials, demos and sample projects to point you in the right direction.

The package is now entirely free, too - no annoying limitations, nag screens or anything else. Epic now only requires that you pay a 5% royalty after the first $3,000 of revenue per product per quarter. And even then, you "pay no royalty for film projects, contracting and consulting projects such as architecture, simulation and visualization."

8.48 brings:
    - Optimized grass rendering and procedural foliage system preview
    - Plugins available in Marketplace
    - Improved accuracy for motion blur
    - New Tone Mapper
    - Support for all the latest VR hardware including Oculus Rift, Samsung Gear VR, Steam VR and HTC Vive, Leap Motion, and Sony's Project Morpheus for PlayStation 4
    - "Scrubbable" network replays with rewind support and live time scrubbing
    - Visualize the memory footprint of game assets in an interactive tree map UI
