RAR → GZ

Learn about the formats: What is RAR? What is GZ?

Convert your RAR archives to GZ format instantly using our tool. This conversion is ideal for users transitioning from Windows-based archiving to Unix-like environments.

RAR is a proprietary archive format commonly used on Windows, capable of multi-part volumes and complex compression algorithms. GZ, or Gzip, is a standard compression utility widely used on Linux and macOS, primarily designed for single-file compression. When converting RAR to GZ, the tool unpacks the RAR structure and re-compresses the data into the Gzip format, which is native to POSIX systems.

As both formats utilize lossless compression, your data remains 100% intact during the process. There is no degradation of file structure or content integrity.

Tips

Ensure your RAR archive is not password-protected before uploading, as encrypted archives cannot be processed.
Remember that GZ is typically used for single files, so large multi-file RAR archives will be consolidated into a single stream.
Check that you have enough disk space, as the extraction process requires temporary storage before GZ re-compression.

Common use cases

Preparing Windows-created backups for deployment on Linux servers.
Standardizing archive formats for cross-platform compatibility in development environments.
Migrating legacy compressed project files to Unix-compatible systems.

Why ConvertX stays free — forever

We built this project so anyone can convert files without paywalls, accounts, or hidden limits. Here is what that promise means in practice.

🎁

Free tools today — and always

Every converter on ConvertX is free to use: no trials, no premium tiers, and no credit packs. We will never put core conversion features behind a subscription. Whether you convert one photo or a hundred files a week, the price stays zero.

🔒

Privacy-first processing

Many image, audio, and video conversions run entirely in your browser. Your files never leave your device for those jobs. When server processing is required for documents or specialized formats, uploads are handled securely and removed automatically — typically within one hour.

🗜️

Images

Raster and vector graphics for web, print, and photography.

Common extensions: PNG, JPG, WebP, AVIF, GIF, SVG, HEIC, TIFF

Advantages

+ WebP and AVIF offer excellent compression for the web
+ PNG keeps transparency and sharp edges
+ SVG scales without quality loss

Disadvantages

− RAW and TIFF files are large and slow to share
− JPEG loses quality on every re-save
− Some formats are not supported in older browsers

📄

Documents

Office files, PDFs, ebooks, and plain text.

Common extensions: PDF, DOCX, XLSX, PPTX, ODT, EPUB, TXT

Advantages

+ PDF locks layout for printing and sharing
+ DOCX and ODT are easy to edit collaboratively
+ Plain text works on any device

Disadvantages

− PDF is hard to edit without special tools
− Complex layouts may shift after conversion
− Scanned PDFs need OCR for editable text

🎬

Video

Clips, streams, screen recordings, and movies.

Common extensions: MP4, WebM, MOV, MKV, AVI, MPEG

Advantages

+ MP4 (H.264/H.265) plays almost everywhere
+ WebM is efficient for web embedding
+ MKV can hold multiple audio and subtitle tracks

Disadvantages

− High-resolution video needs lots of storage and bandwidth
− Re-encoding always takes time and may reduce quality
− Some codecs require licensing for commercial use

Frequently asked questions

The file size changes only marginally because both RAR and GZ are efficient compression formats; the final size depends mostly on the specific compression algorithm settings.

Our tool is optimized for single-volume RAR files; please ensure your multi-part archives are extracted before conversion to GZ.
