PowerArchiver Business

Format coverage that actually covers your inbox

The freebies stop at ZIP and 7Z. Business reads 60+ formats the rest of the world produces — RAR, ACE, ARJ, MSI installers, CHM help, DMG (Mac), ISO/NRG/IMG/BIN disc images, RPM (Linux), VHD, SquashFS, plus 40+ more.

Create

ZIP · ZIPX · PA · 7Z · TAR · GZ · BZ2 · XZ · CAB · ISO · WIM · ZPAQ · PGP · PAE2 — RAR if WinRAR is installed

Read / extract

All of the above plus RAR · MSI · NSIS · CHM · BIN · IMG · NRG · DMG · RPM · CPIO · VHD · SquashFS and 40+ legacy formats (ACE, ARJ, LHA, ZOO, CramFS, MIME / Base64 / UUE for legacy email)

Advanced Codec Pack (.PA format) — better compression than ZIP for the formats you actually share

PowerArchiver's proprietary .PA codec includes purpose-built encoders for PDF, DOCX, PNG, JPEG, and MP3. On those formats, .PA is consistently 30–70% smaller than ZIP and 5–25% smaller than 7Z. Plus a deduplication filter for backup-style archives where the same content repeats.

• PDF codec — re-streams object dictionaries; on average 40% smaller than ZIP for the same files
• DOCX / OOXML codec — recompresses internal ZIP layer at higher ratios
• PNG / JPEG / MP3 — domain-specific filters before LZMA
• Deduplication — content-defined chunking, ideal for incremental backup archives
• Fast vs Strong modes per archive — pick speed or size, both are tuned

AES-256 encryption — strong, broadly compatible, built in

Business ships full encryption — not a teaser. AES-256 ZIP-AES (WinZip AE-2 compatible, also reads 7-Zip's AES), the strengthened PAE2 container with filename encryption + tamper detection, and a built-in password manager so you're not re-typing the same passphrase 40 times a day.

• ZIP-AES — 128 / 192 / 256-bit, WinZip AE-2 + PKZip compatible
• PAE2 containers — Blowfish · DES · 3DES · AES, encrypt-then-MAC, filename + size + timestamp encryption
• Password manager — keep multiple profiles; never re-type a passphrase you've already authorized
• Microsoft CryptoAPI Enhanced Cryptographic Provider — same crypto module Windows Server uses

Strong crypto, but no compliance paperwork at this tier. For OpenPGP signing/verification, the full Chiffrement Suite, or Send-to-Secure-FTP — see Professional. For FIPS 140-2 validated encryption, HIPAA, and DFARS — see Enterprise.

Dual-panel · tabs · queue — UX that beats the file manager

A real archive UI: side-by-side panels, multiple archives in tabs, sequential operations queued like a download manager, drag-and-drop between archives, in-place preview without extracting first. Designed by people who actually use this thing for a living.

• Dual-panel mode — Explorer-replacement that supports drag-and-drop between archives
• Tabbed archives — open ten archives, switch between them like browser tabs
• Operation queue — heavy compression jobs run sequentially without blocking the UI
• Preview window — inspect file contents inside an archive without extracting first
• Native 4K + touchscreen — large hit targets, pen-friendly
• Light / dark themes — system theme auto-detect

Power-user tools you'd otherwise build in PowerShell

Convert between formats. Repair corrupted ZIPs. Batch-compress with a queue. Multi-extract a folder of archives in one operation. Generate SFX (self-extracting) installers. All built in, no separate downloads.

• Convert ZIP ↔ 7Z ↔ TAR.GZ ↔ PA without re-zipping by hand
• Repair truncated or corrupted ZIPs — recover what's recoverable
• Batch compress — feed it a list, walk away
• Multi-extract — point it at a folder of 200 archives, get 200 extracted folders
• SFX creation — wrap an archive as a single .EXE with a custom icon and license dialog
• Encode / decode — Base64, MIME, UUE for legacy email pipelines
