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 7Z compressed archives into TAR format effortlessly. This tool is ideal for users who need to prepare files for Unix-based systems where TAR is the standard format.
The 7Z format is a highly efficient compression container that uses advanced algorithms to reduce file size significantly. In contrast, TAR (Tape Archive) primarily serves as a utility to combine multiple files and directories into a single stream, often without internal compression. When converting 7Z to TAR, our tool extracts the content from the 7Z structure and repackages it into the TAR container, ensuring all file metadata and directory hierarchies remain intact.
Since both formats are lossless, the conversion preserves the original data structure and file content perfectly, with no quality degradation.
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.
