Portable PngOptimizer 2.5



Portable PNGOptimizer is a portable tool that will strip your PNG files of useless or incorrect information, thereby making the filesize of your PNG images smaller. PNGOptimizer can also convert GIF, BMP or TGA image files to optimized PNG images. Moreover, it can be used to automatically create optimized PNG images from screenshots captured via the  print screen key. In simple terms, this tool allows you to optimize your PNG images on the go and convert BMP, TGA and GIF formats into PNG files with the help of this portable and easy to use tool. There's no installation required to use this tool.


Portable PngOptimizer is a handy tool for those who want to save some storage space by compressing their image collection, without making compromise on the graphic quality. Additionally, the application can also be used as a picture conversion tool with support for a single output format: PNG.

Aiming to ease your work as much as possible, Portable PngOptimizer features a straightforward GUI, with no buttons or menus to get in your way. Not even an 'open' button is available and the only way you can load new images is to drag and drop them in the main window.

As soon as a PNG picture is dropped, Portable PngOptimizer starts analyzing it and initiates the optimization procedure. The original and the final file size are displayed, alongside the compression percentage.

The application is set to replace the original files, but you can instruct it to create a backup of them first and save both images in the output location.

What Portable PngOptimizer actually does is remove unnecessary elements from the PNG image, so as to reduce its size without affecting the quality.

As such, it can eliminate the background color, textual data and physical pixel dimensions and the file date. In the 'Options' window you can specify which items to keep, in case you don't want to erase it all.

Despite its name which suggests otherwise, the functionality of Portable PngOptimizer is not limited to compressing PNG files.

It also works as an image converter, enabling you to obtain PNG images out of input GIF, BMP and TGA files. Unfortunately, these three file formats are currently the only supported file types.

Portable PngOptimizer provides you with a simple and fast way to strip your PNG pictures of information you don't need, so as to reduce their size. It supports animated PNG files as well and thanks to its simple approach, optimizing and converting your images is done in just a few seconds.

Furthermore, it is a special version of PngOptimizer that does not require installation, so you can carry it around with you anywhere you go.
