FileOptimizer – A great (and free) Lossless File Optimizer/Compressor

Lossless optimization refers to the process of some decent compression and optimization of various files so that they stay the same, but their size is reduced. Depending on the format of the files and the amount of compression that can be done, you can cut from a few bytes to multiple KBs from the total size of files without any loss in the quality.

Various formats can be losslessly optimized, but in the online world, images are a major part of the webpages so optimization of such images can reduce the overall size of a webpage which will firstly make it easier to load on slower connection and secondly help in powering up the various benchmark scores of your webpages.

This is good because you no longer need to download separate programs for your png, jpg,gif and other image files.

Customization Options

Coming to customization, there aren’t many, but some customization options are available such as Optimization Level and Process Priority which can be changed to obtain the optimization and speed as needed. Setting up Optimization level top Best will naturally take a longer time, whereas setting the Process Priority to something like High or Real Time will provide the program with enough privilege to consume more of system resources to accomplish the task faster. You can also choose from three pre-installed themes, but the default seems to be the best view that you can get.

    I just tried this software on CHM files. i had great expectations, but unfortunately it did not optimize anything at all. All output files have the exact same size than the input files… Why ?

    • Narender Singh February 10, 2015 at 7:57 pm #

      Maybe your file is already fully optimized and there is no further optimization possible?

    Thanks for the reply. No, the file wasn’t optimized. I’ve used FileOptimizer on the source images separately and then I’ve recreated the CHM using the edited images. I had a gain of 60%-80% depending on the CHM files.
