PeaZip is a feature-rich file archiver with broad support for 200+ file types. The file manager interface includes a hash tool, file wipe, file associations, file splitter, themes, estimated compression level, system benchmark, image crop/rename and much more.

Formats supported include most mainstream archive formats, including ZIP, 7Z, ACE, BZIP2, CAB, GZIP, TAR, UPX, ZIPX, as well as it's own PEA format. Can extact but not create MSI and RAR files.

Note that tools setup through the Task Scheduler are not portable.

Bandizip is an archive tool that supports a customisable interface, the searching of archives by file name, file splitting, password protection, self-extracting archives and varying levels of compression. It supports the creation and extraction of most common compression formats, as well as modern formats ZIPX and 7Z.

The program's "High Speed Archiving" function will allow you to compress or bypass the files its own algorithm on multimedia files (AVI, WMV, MP3...) or archive files (ZIP, RAR, 7Z...) that won't benefit from additional compression. This can increase archiving speed dramatically. Extract formats supported include 7Z, ZIPX, RAR, ALZ, EGG, TAR, BH, LZH, BZ2, ISO, CAB, WIM, XZ, ARJ, ZIP, Z and more.

7-Zip is an archive manager that can view and create a wide variety of formats. The program includes folder favorites, optional two-pane view, checksum calculator, file split/combine capability and more. Individual archives can be created with high speed or high compression settings, update options (including update, add/replace, synchronize), split volumes and more. Archives can be secured with standard zip or more secure AES encryption.

Although the official archiver for the open, high-compression "7z" format, the program also supports the creation of multiple formats including ZIP, XZ, BZIP2, GZIP, TAR and WIM. It will extract a long list of other formats, among them RAR, CAB, ISO, ARJ, RPM, VHD, VMDK etc. Even more formats are supported through third-party plugins. Supports many world languages.

Additionally, to use alternative toolbar and file icons, 7-Zip Theme Manager is available.

7-Zip Portable is a wrapper from PortableApps.com, auto-detecting 32 or 64-bit automatically. Alternatively, X-7zip is also available.

There is also a 7-Zip standalone console version.

FUPX (formerly Free UPX) allows you to compress or decompress EXE, DLL, OCX, BPL, CPL and other files. It offers easy access to all documented and undocumented UPX parameters without the need for accessing the command-line.

The program is an advanced interface for the UPX (Ultimate Packer for eXecutables). It uses the Microsoft Portable Executable and COFF Specification.

Alternatively, FUPX Portable is in PortableApps.com Format and includes both the 32-bit and 64-bit versions of the app.

PortableApps.com AppCompactor allows you to compress whole directories including applications, file libraries and zip files. The program is a powerful compression tool that unites 7-Zip and UPX inside a user-friendly wizard. For applications, this saves disk space and increases performance when running from a slow media (like flash drives). For archives, this will recompress DLL, EXE, ZIP, JAR, IRC, PYD and BIN files to their maximum compression settings, as well as an option to decompress an app's binary files that were previously compressed with UPX.

All files are tested using UPX's test feature after compressing. Files smaller than 4K are automatically skipped as compressing will not save space on the drive. The standard Microsoft Visual C runtimes are skipped to prevent antivirus false-positives. Advanced configuration can be done with apps in PortableApps.com Format.

Note: As UPX will alter the EXEs and DLLs (reversible using the Decompress option in the AppCompactor) and some apps may have issues with Zip or Jar files compressed further, users should backup software and test it after processing.

IZArc is an archive utility that supports drag-and-drop, searching inside archives, 50 different formats, archives broken into sections (spanning), the creation of self-extracting archives, repair of damaged ZIP archives, converting from archive type to another, create/merge multi-volume sets, etc. The program decompresses popular formats ZIP, RAR, 7Z, as well as CD image formats (ISO, BIN, NRG, IMG etc), while compressing to 7Z, JAR, ZIP, and many more, using their native speed/quality options and encryption methods.

IZArc2Go is the portable version of IZArc by the same author.

Universal Extractor 2 is an easy-to-use extraction program that works on a long list of file types including standard compression formats like ZIP, RAR and 7Z files, as well as program installers, disk images, audio/video and many more. The program also includes an "scan" option to view available data on a setup file, integrated updater, improved status box, new detection methods for files, batch extraction, plugin support and more.

The program is an unofficial fork of Universal Extractor.

PeaExtractor is a easy, minimalistic tool for unpacking almost any compressed file format. Features a search tool, progress bar and drag-and-drop functionality. The program can unpack over 180 formats including encrypted or multi-volume archives (usually a series like .000, .001 or .r01, .z01...) as well as standard formats like 7z, rar, tar, zip, zipx, bzip2, cab, iso etc.

The program aims to function as a simple, accessible alternative to file manager-like interfaces used by WinRAR, WinZip and 7-Zip. Cross-platform (Linux, BSD) and developed by the author of PeaZip.

NOTE: Open ACE files with additional steps. The download also includes pea.exe, containing other tools including checksums, secure delete, file lists and more.

InnoEx is a small and simple front-end for InnoUnp for viewing and extracting of resources from Inno Setup installers. It is fast and easy to use, it supports drag and drop (both ways) and Windows shell integration.

ArcConvert converts between a wide variety of archives and includes automatic password detection. The program supports drag-and-drop, process priority, file check, and optional attributes (date/time). The program will even notify the user if the new file is larger than the original.

Ideal for upgrading compression (e.g. ZIP -> 7ZIP) or to change an archive to a format supported by your preferred program (e.g. RAR -> CAB).

Supports a long list formats are supported including ZIP, 7-ZIP, RAR, TGZ, as well as ~60 other lesser-known formats. The program can save to ZIP, 7-ZIP, CAB, LHA, TAR, TGZ, BZ2, YZ1, BGA, RAR, ACE, NOA32, PAQAR, UHARC, YZ2, DZ, HA, XZ, and FreeArc

• Automatically-named ZIPs based on filename (file1.txt and file2.txt --> file1.zip and file2.zip)

Simplyzip is a multi-archiver program that supports numerous formats, including ZIP, ACE, CAB, RAR, TAR, GZIP, LZH, BZ2 etc. It has additional functions such as ACE/ZIP repair tool, file encryption/decryption, multi-ZIP spanning etc.

SFXMaker is an automation tool for unattended software installations, also known as switchless installers or silent installs. This program especially ideal for those who use nLite, as it adds the option of creating an installer for nLite in the GUI.

There are also more recent versions of SFXMaker, but they require administator rights.

Universal Extractor allows you to extract files from a wide variety of archive files, including ZIP, ARJ, LZH, as well as MSI and EXE files created using various installer packages (such as Nullsoft, Wise, Inno Setup, etc). Useful for testing apps for portability because you can extract files directly from installer packages without having to go through the installation process. Note that the original developer no longer updates the program so some manual updates may be required.

Alternatively, an unofficial version with the latest-and-greatest internals is available (on Lupo's PenSuite site).

Commercial use note: license restrictions are present on included files UHARC02.EXE and UHARC04.EXE, but can be deleted without dramatic impact on the software. See website for more information.

UPX is a tool that can reduce the size of system files (EXE and DLL) significantly. No additional software is required after compression and some programs will even run faster due to fewer read operations.

UPX Tool is a GUI wrapper for UPX, able to both compress and decompress.

There is an unofficial update created by Lupo PenSuite (UPX Tool+ 1.1.1) that can be download here. The main advantage of this update is functionality with UPX 3.0 (improved compression via LZMA).

nPack is a Win32 PE executable file compressor. It supports all types of PE files (EXE, DLL, OCX), and compresses program code, data and resources. However, it does not provide support for decompressing PE files that have already been compressed.
