Some compression tools like Seven Zip, WinZip or even WinRAR are able to effectively reduce the size of archives by a considerable amount, however nothing comes close to the power and versatility of KGB Archiver. KGB Archiver can turn your large files into something much smaller by compressing them into KGB's own compression format, with further support for creating ZIP files with similar compression ratios.
KGB offers you the ability to choose which compression rate you'd like to use for making files smaller; you can choose from between minimum compression rate to a maximum compression rate and turn a digital photo which weighs in at 4.0MB to a compressed size of only around 1.3MB. KGB Archiver certainly isn't the fastest compressor out there, but it is by far one of the most effective at reduce filesizes.
There are some pitfalls of using this archiver; for one, browsing archives can take a little bit longer depending on the size. Compared to Seven Zip, KGB is painstakenly slow. This application is also known for using a high amount of system resources and as such, you should only use it when you really must shrink the size of files.
As an added bonus of extremely high compression rates, KGB Archiver also supports archive encryption. You are able to set any password you'd like on the archives it creates, but don't forget that there are virtually no password crackers out there for KGB archivers, so make sure you keep your passwords in a very safe place and consider using a password manager.
