Modded 7zip For Lz4 __top__ Page

When looking for a "modded 7-Zip for LZ4," the primary and most robust solution is

, developed by mcmilk. This version integrates modern compression algorithms—including LZ4, Zstandard (ZSTD), Brotli, and Lizard—into the familiar 7-Zip interface. Why Use 7-Zip ZS for LZ4?

LZ4 provides extremely fast compression (>500 MB/s per core) and decompression (~GB/s per core), making it ideal for scenarios where speed matters more than the smallest file size. Compatibility:

This modded version (7-Zip ZS) enables LZ4 support within the popular 7z container, allowing for better organization than raw LZ4 files. GUI & CLI:

It includes both a graphical interface and command-line support, just like the official 7-Zip. How to Use LZ4 in 7-Zip ZS Download and Install: Obtain the latest version of 7-Zip ZS from GitHub Compress Files: Right-click the files you want to archive, select , and choose modded 7zip for lz4

While the official version of 7-Zip is legendary for its LZMA2 compression, it lacks native support for the lightning-fast LZ4 algorithm. To bridge this gap, enthusiasts and developers use "modded" versions or plugins to enable real-time, high-speed compression within the familiar 7-Zip interface. Top Modded Versions for LZ4 Support

7-Zip Zstandard (7-Zip ZS): This is the most popular and comprehensive mod. It extends 7-Zip to support several modern algorithms, including LZ4, Zstandard, Brotli, and Lizard. It is highly active, with recent releases including LZ4 Version 1.9.4. You can download the latest builds from the 7-Zip-zstd GitHub repository.

NanaZip: A modern derivative of 7-Zip specifically designed for Windows 10 and 11. It inherits the compression methods from 7-Zip ZS, meaning it supports LZ4 out of the box while offering a more integrated experience with the modern Windows context menu. It is available on GitHub and the Microsoft Store.

Modern7z: Rather than a full replacement of the executable, this is a plugin for the official 7-Zip. By placing the plugin files into a "Codecs" folder within your 7-Zip installation directory, you can add support for LZ4 without switching to a different application version. It is maintained at TC4Shell. Why Use LZ4 in 7-Zip? When looking for a "modded 7-Zip for LZ4,"

LZ4 is designed for extreme speed over maximum compression ratio. While LZMA2 (the 7-Zip default) might take minutes to squeeze a file to its smallest size, LZ4 can often compress data at speeds exceeding 500 MB/s per core. Best use cases for modded LZ4 support:

Real-time Backups: When you need to back up large datasets (like log files or database dumps) without bottlenecking your CPU or storage.

High-Speed Transfers: Compressing data quickly before sending it over a network where the speed of compression is more valuable than saving every last kilobyte.

Low-Resource Environments: LZ4 is significantly lighter on system resources compared to heavy algorithms like xz or 7z-standard. Performance Comparison Compression Speed Decompression Speed LZ4 Extremely Fast Ultra Fast Zstandard LZMA2 Highest 1–12 for HC

Reviewers on Hacker News note that while Zstandard is often seen as the modern "middle ground," LZ4 remains the undisputed king for pure speed. Releases · mcmilk/7-Zip-zstd - GitHub

Here’s a breakdown of what a modded 7-Zip with LZ4 support would need feature-wise, since official 7-Zip doesn’t natively support LZ4 compression (only LZMA, LZMA2, PPMd, etc.).

If you’re looking for a custom build or adding LZ4 to 7-Zip, these are the key features to implement:

The Future: Will LZ4 Ever Be Official in 7‑Zip?

There is a long-standing feature request on the 7‑Zip SourceForge page (#1665 and #2047). Igor Pavlov has hinted that future major versions (perhaps 7‑Zip 25.00+) might adopt a plug-in codec architecture, which would allow adding LZ4 without forking. But as of 2025, there is no official timeline.

Until then, the modding community is doing God’s work. The 7‑Zip ZS fork alone has over 2.5 million downloads, proving that speed-oriented compression is not a niche—it’s a necessity.
