Convert LZ to RAR
Fast, free, and secure LZ to RAR conversion. No registration required.
No app to install, no account to create — just open this page, drop your lz file, and get rar output in seconds. What makes this conversion useful: Lzip Compressed gives you reliable compression with CRC-32 data integrity verification, but RAR Archive unlocks file distribution, software packages and compressed downloads — something Lzip Compressed struggles with (slower than gzip, limited Windows tool support). This is one of the most frequently used conversions on Xonvert, with 431 daily conversions on average. The entire conversion pipeline runs in a sandboxed WebAssembly environment for maximum security and performance.

LZ to RAR: Quality Comparison
Dynamic range — the span from darkest to brightest values — is handled carefully during this conversion. Lzip Compressed preserves the full range. RAR Archive optimizes for typical display capabilities. Xonvert preserves embedded metadata (EXIF, XMP, ID3 tags, etc.) whenever the RAR Archive format supports it. Format-exclusive metadata fields that have no equivalent in RAR Archive are gracefully omitted without affecting the converted content. Quality in this conversion depends primarily on your source file. A high-quality Lzip Compressed input produces an excellent RAR Archive output. Xonvert defaults to high quality settings that keep file size reasonable without compromising perceivable quality.
Re-packaging files from Lzip Compressed to RAR Archive 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.
Compression trade-off: Your lossless LZ source retains all original data. Converting to lossy RAR will reduce file size substantially, but some data is permanently discarded. Use the quality slider to balance file size against fidelity.

LZ to RAR FAQ
What's the maximum number of files I can convert at once?▼
Free users can convert several files per batch. PRO users enjoy unlimited batch sizes. For very large batches, your device's memory is the only practical limit.
Why choose RAR over other formats?▼
RAR Archive offers strong compression with recovery records and solid archive support. It's widely used for file distribution, software packages and compressed downloads, making it an excellent choice for most archive needs.
Will my LZ file be deleted after conversion?▼
No. Your original LZ file is never modified or deleted. Xonvert creates a separate RAR copy — your source file remains untouched.
What archive quality settings should I use?▼
Default settings are optimized for the best balance of quality and file size. Adjust only if you have specific requirements.
Does this work on my phone or tablet?▼
Yes. Xonvert works on any device with a modern browser — iPhone, iPad, Android phones and tablets all supported.
Can I undo a conversion?▼
Since your original LZ file is never modified, there's nothing to undo. Your source file remains exactly as it was — only a new RAR copy is created.
What if my LZ file won't convert?▼
Ensure the file isn't corrupted or DRM-protected. Try a different file to verify. If issues persist, the file may use an unsupported codec variant.
