Files - Compression/Decompression (19)

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

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.

FileOptimizer is a broad format file compression tool used to reduce file size without changing the quality, known as "lossless." This is done via wide variety of optimization and recompression tools and techniques. Original files are sent to the recycle bin for restoration in the event the uncompressed version is preferred. A list of the 400+ supported formats include audio/video (MP3, OGG, M4A), image (GIF, JPEG, PNG), office formats (DOCX, XLSX, ODT, PDF) and system files (DLL, EXE).

Supports drag-and-drop of files into the window or onto the program icon. Note that by default the program removes metadata for many file types. This information reduces overall file size and protects privacy but is important to some users (e.g. photographers) and file search tools.

A 64-bit version is available within the folder, the author reports the program is functional in WINE, and can be used on the command line. Many images here on TPFC including our logo have been compressed using FileOptimizer.

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.

Cross platform with clients for Mac, Linux, and BSD, as well as a 64-bit version is available. Alternatively, PeaZip Portable portablizes bookmarks and includes both 32 and 64-bit versions, automatically using the proper one on each PC.

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.

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.

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.

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.

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.
