PowerArchiver 2018 is the most advanced release of PowerArchiver ever. We made PowerArchiver up to 3x faster, difference that you will notice immediately. It also uses less memory and still looks great. We also implemented a built in PDF engine for easy and fast previewing of all kinds of PDF files. In addition to all those changes, we have implemented a much stronger ZIP Deflate engine that will create smallest possible, yet compatible ZIP files with full multi-core support (as many threads as your CPU supports – 16? 24? It works!) . For full list of changes in the new PowerArchiver 2018, please check out PowerArchiver 2018 Introduction.

We have also implemented a new skinning section on our website, with support for PA 2018 Skins. Check it out now.

PowerArchiver 2018 BETA 2, with the Advanced Codec Pack (.PA), is now available from our download page as well as Patchbeam for PowerArchiver 2018 users. Thank you for your support since 1998!
