Any file up to 500 MB. Drop several files and they come back as one ZIP. Many image, audio and video conversions run in your browser; anything else is uploaded and removed within the hour.
Convert your GZ archives to RAR format effortlessly with our tool. This solution is ideal for users who need to switch from Unix-based compression to the multi-volume archive structure supported by WinRAR.
GZ (GNU Zip) is primarily used on Unix systems for single-file compression, while RAR is a proprietary format that excels in data recovery, multi-part volume splitting, and advanced compression algorithms. When converting GZ to RAR, our system unpacks the GZ stream and re-encapsulates the data into a RAR container, allowing you to take advantage of RAR-specific features like recovery records and spanning across multiple files.
As both formats utilize lossless compression algorithms, the conversion process preserves your data integrity completely without any loss in file quality.
We built this project so anyone can convert files without paywalls, accounts, or hidden limits. Here is what that promise means in practice.
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.
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.
A quick guide to strengths and trade-offs of popular formats — so you pick the right one before converting.
