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 ZIP archives to TXZ (TAR.XZ) format effortlessly. This tool is ideal for users who need to optimize storage or prepare files for Linux-based distributions.
ZIP is a widely used archive format that prioritizes speed and compatibility. In contrast, TXZ combines the TAR archiver with XZ compression, which offers significantly higher compression ratios, making it perfect for reducing the size of large data sets or software source code.
The conversion is lossless; all original files and directory structures remain intact during the transition from ZIP to TXZ.
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.
