PeaZip is a free archiver tool. The application provides an unified, natively portable, cross-platform file manager and archive manager GUI for many Open Source technologies like 7-Zip, FreeArc, PAQ, UPX. Create: 7Z, ARC, Brotl, BZip, GZip, PEA, TAR, WIM, XZ, ZPAQ, ZIP, Zstandard files and more Open and extract 200+ file types: ACE, CAB, DEB, ISO, RAR, ZIPX and more Features of PeaZip includes extract, create and convert multiple archives at once, create self-extracting archives (sfx), split files, strong encryption with two factor authentication, encrypted password manager, secure deletion, find duplicate files, calculate hashes, export task definition as command line script.

FreeArc combines best 7-zip and RAR features: auto-selected LZMA/PPMD/Multimedia compression, 1gb dictionary, exe/dict/delta data filters, updatable solid archives, SFXes, recovery record, AES+Twofish+Serpent encryption, Linux support and much more...

FLAC is a free lossless compressed audio format which supports streaming and archival. The FLAC project maintains the format and provides a reference encoder/decoder and input plugins for several popular audio players.

KGB Archiver is the compression tool with unbelievable high compression rate. It surpasses even such efficient compression tool like 7zip and UHARC in terms of the abilities. KGB Archiver uses AES-256 encryption to encrypt archives.

Lossless compressor for multichannel 8,16 and 24 bits audio data, with the ability of password data protection. Being 'lossless' means that no data/quality is lost in the compression - when uncompressed, the data will be identical to the original.

As Speek's celebrated FLAC Frontend hasn't been updated for 10 years, things started to get a little buggy with new Windows versions. This remake fixes most issues. FLAC Frontend is a convenient way for Windows users not used to working with command lines to use the official FLAC tools. It accepts WAVE, W64, AIFF and RAW files for encoding and outputs FLAC or OGG-FLAC files. It is able to decode FLAC files, test them, fingerprint them and re-encode them. It has drag-and-drop support too.

IMPORTANT NEWS: UPX has moved to GitHub https://upx.github.io ========================

Advanced archiver (zpaq fork) with deduplication and versioning. Never prune your backups: keeps a forever-to-ever copy (even thousands of versions) of your files, conceptually similar to Mac time machines, or zfs' snapshots, but much more efficiently. Ideal for virtual machine backup and "freezing" zfs snapshots forever. Easily handles millions of files and TBs of data. Allows rsync backups to the cloud (or NAS, or USB) with minimal data transfer, encryption and very limited bandwidth. Highest possibilities of data verification, fast, deep and even paranoid-level, with support for multithread acceleration on SSD/NVMe (real world 1GB/s+). Freeware Win GUI (PAKKA) here https://www.francocorbelli.it/pakka/build/latest No complex repository folders, just one file. Latest "hashers" (SHA-3, BLAKE3 w/HW acceleration on Win, XXH3) 15+ years of developing (2009-now). Seeing is believing! https://github.com/fcorbelli/zpaqfranz/wiki

minidjvu is a DjVu encoder for black-and-white images.

Draco is an open-source library for compressing and decompressing 3D geometric meshes and point clouds. It is intended to improve the storage and transmission of 3D graphics. Learn about compressing and viewing 3D models with Draco, and about different compression models and their effects. Draco was designed and built for compression efficiency and speed. The code supports compressing points, connectivity information, texture coordinates, color information, normals, and any other generic attributes associated with geometry. With Draco, applications using 3D graphics can be significantly smaller without compromising visual fidelity. For users, this means apps can now be downloaded faster, 3D graphics in the browser can load quicker, and VR and AR scenes can now be transmitted with a fraction of the bandwidth and rendered quickly.

A SEGA Dreamcast VMU backup utility that allows you to transfer your savegame files from/to your PC harddisk.

My first try of a GUI with wxWidgets. Now 7zip can do "each file to a seperate archive" from Winrar. Sends commands to the CMD to process through the list, though maybe Admin rights are required. Maybe a Linux-Version later...

QUAD is a command-line file compressor with a good compression ratio and fast decompression. Please note: This program was succeeded by the BALZ.

CRUSH is a simple LZ77-based file compressor that features an extremely fast decompression.

torrent7z is a replacement for TorrentZip for goodmerged sets.

Easy 7-Zip is an easy-to-use version of 7-Zip. Easy 7-Zip was built based on 7-Zip 9.20. It kept all features of 7-Zip and added a few useful features that makes the software more user-friendly.
