About formats

ALZ is a proprietary archive format created by ESTsoft, a South Korean software company, as the native format of their ALZip archiver first released in 1999. The format was designed to address a specific need in the Korean market: splitting large archives into multiple volumes for distribution when email attachment size limits and slow internet connections made transferring large files impractical. ALZ archives support file compression, multi-volume splitting with configurable segment sizes, and basic file organization with directory structures. The format became widely adopted in South Korea, where ALZip established itself as one of the most popular archiving utilities due to its free availability for personal use and localized Korean interface. At its peak, ALZip was installed on a majority of Korean personal computers, making ALZ a common interchange format for file sharing within the country. One advantage is reliable multi-volume handling — ALZ was specifically engineered for splitting and reassembling archives across volume boundaries, a feature that was central to its design rather than an afterthought. The format's tight integration with ALZip provides a streamlined user experience for compression and extraction tasks. While ALZ saw limited adoption outside South Korea due to the availability of universal formats like ZIP and RAR, it remains encountered in files originating from Korean sources and can be extracted using ALZip, 7-Zip, and other compatible utilities.

RAR (Roshal Archive) is a proprietary compressed archive format created by Russian software engineer Eugene Roshal in March 1993, distributed through the WinRAR) archiver that became one of the most widely installed Windows applications worldwide. The format uses a sophisticated compression algorithm that has evolved through several major versions (RAR 1.3, 2.0, 3.0, 5.0), with each revision improving compression ratios and adding features. RAR5, the current version, employs a dictionary-based algorithm with dictionary sizes up to 1 GB and supports optional BLAKE2sp hashing for integrity verification. The format provides solid compression (treating multiple files as a continuous stream), multi-volume archive splitting, recovery records for repairing damaged archives, AES-256 encryption for both content and filenames, and Unicode filename support. One advantage is reliable error recovery — RAR's recovery record feature can reconstruct damaged archive portions, a capability that made it popular for distributing large files across unreliable connections and Usenet posts. Strong compression performance is another key strength: RAR consistently ranks among the top formats for general-purpose compression ratios, particularly on heterogeneous file collections. While the compression algorithm is proprietary and creating RAR archives requires licensed software, the decompression code is freely available, and extraction is supported by virtually every archiving tool across all platforms. RAR remains one of the most common archive formats encountered online.

Frequently Asked Questions

Why switch from ALZ to RAR?

ALZ requires ALZip and is virtually unsupported outside South Korea. RAR is recognized globally, with WinRAR and 7-Zip available everywhere.

How do I open RAR files?

WinRAR is the native tool. 7-Zip (free) also handles RAR perfectly. On macOS, use The Unarchiver. Linux users have unrar available.

Does RAR offer any advantages over ALZ?

RAR includes recovery records for repairing damaged archives, solid compression for better ratios, and much wider software support.

Will converting change my file contents?

Not at all. Convertio preserves every file and folder from your ALZ archive exactly as they are — only the container format changes.

Can I convert without installing ALZip?

That's the whole point. Convertio handles ALZ extraction on its servers — you never need ALZip or any other software on your machine.
