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.
Easily convert your 7Z archives into GZ format with our online tool. This transition is essential for users moving data from Windows-centric compression to Unix-like environments.
The 7Z format is a high-compression container often used for multi-file storage, while GZ (Gzip) is a single-stream compression standard native to Linux and Unix systems. When converting 7Z to GZ, our service extracts the contents of the 7Z archive and re-compresses them using the Gzip algorithm. This process ensures that your files become compatible with standard command-line tools like tar and gzip, which are fundamental for server-side operations and software distribution in Unix environments.
Since both formats utilize lossless compression, your data remains 100% intact. There is no reduction in file quality during the conversion process.
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.
