About formats

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.

LHA (originally LHarc) is a compressed archive format created by Haruyasu Yoshizaki (known online as Yoshi) in May 1988, combining Lempel-Ziv) sliding-window compression with Huffman coding for efficient data reduction. The format achieved enormous popularity in Japan, where it became the dominant archiving standard throughout the late 1980s and 1990s — virtually all Japanese software distribution, from commercial applications to BBS file sharing, relied on LHA archives. The format stores files with per-entry headers containing filename, timestamps, OS-specific attributes, and CRC-16 checksums, using various compression methods designated by two-character codes (lh0 through lh7, with lh5 being the most common general-purpose algorithm). LHA's compression algorithms were influential beyond the format itself: the lh5 method's approach to combining LZSS with static Huffman coding was adopted by the Deflate algorithm used in ZIP, gzip, and PNG. One advantage is the format's historical efficiency — LHA offered strong compression ratios with modest CPU requirements, critical on the relatively slow processors of its era. The format's deep cultural impact in Japanese computing is another notable aspect: LHA was freely distributed, contributing to its ubiquitous adoption across the Japanese software ecosystem. While modern formats have superseded LHA for new archives, it remains relevant for accessing Japanese software archives and retro computing collections, with extraction supported by 7-Zip and other contemporary tools.

Frequently Asked Questions

Why convert RAR to LHA?

LHA is used in specific retro computing communities, Japanese software distribution, and Amiga platforms where it remains the expected archive format.

What programs open LHA archives?

The lha command-line tool works on Linux. On macOS, The Unarchiver handles LHA, and 7-Zip supports LHA extraction on Windows.

Is RAR to LHA conversion free?

Entirely free. Convertio.tools provides this conversion with no charge, no registration, and no daily usage caps.

Can I use this on a Mac?

Yes — the converter is a web tool that works in Safari, Chrome, Firefox, and any other browser on macOS, as well as every other platform.

Are nested folder structures preserved?

They are. The full directory layout of your RAR archive, including all nested paths, is maintained in the LHA output.

Is batch conversion supported?

Yes. Upload multiple RAR archives and convert them all to LHA at once — the batch feature handles every archive in a single operation.
