PowerArchiver 18.02.02

Two base modes: Optimized Fast and Optimized Strong deliver the fastest/strongest compression in the industry.
Smart Optimized modes select the best compression/speed ratios on per-file basis, increasing compression rate and speed. In one compression scenario, PowerArchiver can use multiple codecs for different files/extensions! This provides much better compression/speed since we can target codecs better.
Optimized Fast – fast compression modes with 50MBs-400MBs compression speeds, depending on files and strength chosen. Data deduplication features and compression stronger than zip format.
Optimized Strong – Strong compression features at reasonable speeds even at Extreme level. Optimized for processors with 4 and more threads. Supports multicore extraction and data deduplication. Special coders for stronger levels delivering better compression than comparable options in competing software.
PDF, DOCX and PNG compression – compress your PDF and DOCX (Office) files between 30% and 70% better than WinRAR, WinZip and 7zip. Also used for PNG, APK, ZIP and other files with deflate streams.
FIPS 140-2 256-bit AES encryption – Advanced Codec Pack (.PA) is very secure. Not only we use FIPS 140-2 validated encryption components, we also apply special transformation filter that ensures that the data being encrypted does not have any LZ compression markers that could make brute-force attacks easier. We consider it considerably more secure than encryption methods available in ZIP and RAR formats.
JPEG codec – uses Lepton compression for jpeg files, strong compression up to 23%.
MP3 codec – Strongest and fastest MP3 compression codec on the market with full multi-core support. Better compression and up to 3x faster speeds than WinZIP MP3 compression.
Special Deduplication filter – fast filter that finds similar data at 50MB/s speeds (single thread). Works great for similar files that have some similar data, for instance when backing up your office files, this filter should increase compression ratios significantly. Compressing Software ISO’s with deduplication filter can lower the size by extra 500MB compared to WR, WZ, 7-zip (Office 2016 ISO 2.25GB example), with super-fast compression.
Special codec for compressing txt/html/xhtml files. Better compression at faster speeds, multi-core optimized.
Special exe/dll filters – collection of special filters that improves compression up to 10-15% for exe/dll files.
Multi-core extraction – Most codecs have multi-thread support based on our mtwrap which automatically gives you multi-threaded extraction. This means that extraction is also fast despite use of advanced and strong compression.
Custom compression profiles – Extensive support for custom compression profiles that let you configure 20+ codec options thus making sure you can setup special case scenarios that work the best for your own data.
Actively developed in-house, with frequent updates and new future codecs, optimizations and more. Currently over 10 filters/codecs are transparently used at the same time depending on file and options selected.

.pa and 7z optimized mode: write directly to archive (much faster on huge files).
Better and faster update process for .pa and .7z archives (seamless updates).
Delete does not work in .pa archives (sometimes).

Advanced Codec Pack:
Advanced Codec Pack – .pa format is an advanced collection of codecs and filters that, when combined together, create the .pa format. It features two main modes:
Optimized Strong mode brings very strong compression to .pa format, with special codecs for pdf/docx files, exe/dll files, jpeg files, text/html files and many more. It provides for best overall compression currently available in professional compression software. Compared to WinZIP (zipx), it is several times faster while providing for better compression.
Optimized Fast mode that is optimized for speed and includes the super fast base codec as well as data deduplication and exe/dll filters. This combination of codecs and filters is much faster than zip while also creating smaller files.
64bit version: – Advanced Codec Pack can use maximum ram and cpu from your system, which lead us to creating a native 64bit version of PowerArchiver. It is now recommended to always use the 64bit version of PowerArchiver to get the maximum performance from .pa format.
Dual panel explorer mode – Dual explorer panels for easier file management.
Faster ZIP/ZIPX engine – by many benchmarks, our ZIP/ZIPX engine was already the fastest. Now it is even faster!
Multithreaded 7zip engine – up to 8x faster than before, along with additional improvements for 7zip support.
Portable version – Fully supported portable version for USB drives! Both 32bit and x64 bit!
Improved interface – Streamlined options, faster start time, better support for skins, beautiful looking.
PowerArchiver for Office – Our Microsoft Office add-ins now support Microsoft Word and Microsoft Excel as well as additional features in Microsoft Outlook.
