Convert RAR to LZ
Fast, free, and secure RAR to LZ conversion. No registration required.
No app to install, no account to create — just open this page, drop your rar file, and get lz output in seconds. What makes this conversion useful: RAR Archive gives you strong compression with recovery records and solid archive support, but Lzip Compressed unlocks data archival with integrity guarantees — something RAR Archive struggles with (proprietary format requiring WinRAR or compatible tools). This is one of the most frequently used conversions on Xonvert, with 511 daily conversions on average. This conversion is instant for most file sizes. Large files may take a few extra seconds of processing.

RAR to LZ: Quality Comparison
Dynamic range — the span from darkest to brightest values — is handled carefully during this conversion. RAR Archive may clip extreme values. Lzip Compressed maintains the complete dynamic range. Xonvert preserves embedded metadata (EXIF, XMP, ID3 tags, etc.) whenever the Lzip Compressed format supports it. Format-exclusive metadata fields that have no equivalent in Lzip Compressed are gracefully omitted without affecting the converted content. Quality in this conversion depends primarily on your source file. A high-quality RAR Archive input produces an excellent Lzip Compressed output. Since the target format is lossless, output quality matches your input exactly.
Re-packaging files from RAR Archive to Lzip Compressed archive format changes the compression algorithm and container structure while preserving all archived contents. File permissions, directory structures, and timestamps are maintained when supported by both formats. This conversion is useful when a recipient's system requires a specific archive format.
Important: Converting from lossy RAR to lossless LZ does not restore previously discarded data. The output perfectly preserves your current file quality without adding further degradation, but quality lost during the original RAR encoding cannot be recovered.
