Files - Compression/Decompression (20)

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 long list of 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.

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.

PeaZip is a feature-rich file archiver with broad support for 100+ archive types.  The file manager interface includes a hash tool, file wipe, file associations, themes, estimated compression level, system benchmark, image crop/rename, and much more. Note that tools setup through the task scheduler are not portable.

Formats supported include most mainstream archive formats, including 7ZIP, ACE (read), BZIP2, CAB, GZIP, MSI (extr.), RAR (extr.), TAR, UPX, ZIP, as well as it's own PEA format.

Cross platform (Linux/BSD) and 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.

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 150 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.
