What's the difference between Z and LZ?

Z Compressed is unix compress — one of the earliest unix compression utilities. Lzip Compressed is lzma-based lossless data compressor with integrity checking. Key difference: Z Compressed excels at historical importance as original Unix compression tool, while Lzip Compressed offers reliable compression with CRC-32 data integrity verification.

How does the Z to LZ conversion work technically?

Xonvert uses WebAssembly-compiled libraries to decode your Z file in-browser, process the archive data, and re-encode it as LZ. All processing happens on your device's CPU.

What happens to my files after conversion?

Nothing — your files exist only in your browser's memory during conversion. Once you close the page, all data is cleared. No files are stored anywhere.

Z Compressed is Unix compress — one of the earliest Unix compression utilities. It is primarily used for legacy Unix archives and historical data. Uses LZW (Lempel-Ziv-Welch) compression algorithm

Will the conversion strip my EXIF or metadata?

Xonvert preserves metadata (EXIF, XMP, ID3, etc.) when the target LZ format supports it. You can optionally strip metadata in the settings for smaller, cleaner output files.
