Repackage RAR Archive as GZ
Proprietary format — creating RAR files requires WinRAR (paid license), though extraction is free via unrar/7-Zip. Converting to GZ gives you a key advantage: universal unix standard — built into every linux distribution, used by http content-encoding, and combined with tar for .tar.gz archives. GZ is best for compressing single files and tar archives on unix/linux systems using the standard deflate algorithm.
Why Convert RAR to GZ?
Proprietary format — creating RAR files requires WinRAR (paid license), though extraction is free via unrar/7-Zip — converting to GZ overcomes this by providing universal unix standard — built into every linux distribution, used by http content-encoding, and combined with tar for .tar.gz archives
GZ is the right choice when you need to: compressing tar archives into .tar.gz (tgz) for unix software distribution
Gain broader compatibility — GZ works with Linux/macOS (native), Windows (7-Zip, WinRAR), HTTP servers, all programming languages
Your RAR files were created for creating archives with recovery records for reliable transfer over unreliable connections, but now you need a format suited to different workflows

How to Convert RAR to GZ
Upload your RAR file
Drag your .rar file onto the upload area or click to browse. We accept RAR files up to 2 GB.
Choose GZ as output format
Select .gz (gzip Compressed File) from the format list. GZ uses lossless compression, so your output quality matches the source.
Convert and download
Click Convert and wait for processing. Your GZ file will be ready to download in seconds. The result is optimized for compressing single files and tar archives on unix/linux systems using the standard deflate algorithm.
Frequently Asked Questions
Is the RAR to GZ conversion lossless?
expand_more
When both formats support lossless data, the conversion preserves all content. DEFLATE compression (same as ZIP); fast decompression at the cost of moderate compression ratios.
How large will my GZ file be compared to the original RAR?
expand_more
RAR files are typically 1 KB – unlimited (multi-volume), while GZ files are typically 1 KB – 2 GB. The actual size depends on content complexity and any quality settings you choose.
What software can open the converted GZ file?
expand_more
GZ is compatible with: Linux/macOS (native), Windows (7-Zip, WinRAR), HTTP servers, all programming languages.
What is the maximum file size I can convert?
expand_more
PureConverter accepts RAR files up to 2 GB. Your files are processed securely and deleted from our servers after conversion.
What's the difference between RAR and GZ?
expand_more
RAR (Roshal Archive) is best for compressing large files with recovery records that protect against download corruption. GZ (gzip Compressed File) is best for compressing single files and tar archives on unix/linux systems using the standard deflate algorithm. Key tradeoff: RAR's advantage is built-in recovery records can repair corrupted archives, and solid compression mode achieves ratios better than zip, while GZ's advantage is universal unix standard — built into every linux distribution, used by http content-encoding, and combined with tar for .tar.gz archives.
Pro Tips for RAR to GZ Conversion
GZ preserves full quality, so your output file will be as good as the RAR source — no need to worry about compression artifacts
Keep a backup of your original RAR file — while our conversion is reliable, having the source is always recommended
GZ works especially well for: compressing log files for rotation and long-term storage on unix servers
Did you know? gzip was created as a free replacement for Unix "compress" after the LZW patent controversy — the same patent issue that created PNG to replace GIF. Both gzip and PNG use the patent-free DEFLATE algorithm.
