Free ZIP to TGZ converter

Why convert ZIP to TGZ?

People convert ZIP to TGZ because ZIP is universal but compresses less tightly than the formats built for the job, while a .tar.gz is the standard way to ship a folder on Linux and macOS.

How to convert ZIP to TGZ

1. Choose your ZIP file. Drop it on the box above, or tap to browse. You can pick several files at once.
2. Confirm the target is .tgz. It is preselected when your browser can encode it; otherwise the closest available target is chosen. Adjust quality, size or the other options if you want to.
3. Convert and download. Press Convert, then Download. Your file stays on your device the whole time.

What is a .zip file?

ZIP bundles many files into one and compresses them, and every operating system has opened one natively for decades. It is the default way to send a folder to another person, and the container hiding inside DOCX, XLSX, EPUB and countless other formats.

What is a .tgz file?

A TGZ is a TAR archive that has then been gzipped: the bundling and the compression done by two separate tools, as Unix prefers. It is the standard distribution format for source code and Linux packages.

What to expect from this conversion

The conversion runs entirely in your browser and the file never leaves your device. The archive is repacked, not re-compressed file by file, so the contents are untouched.

Is it private?

Yes, by design. Every conversion happens inside your own browser using your device’s processor — there is no server that receives your ZIP file, so there is nothing for anyone to store, scan or leak. You can confirm it yourself: open your browser’s developer tools, watch the Network tab while you convert, and you will see no upload.

Can I convert ZIP to TGZ without the command line or a script?

Yes — that is what this page is for. the command line does the same job well if you already have it set up and thousands of files to process; for one file, or a handful, the browser is faster than installing anything.

Should I keep the original ZIP file?

Yes — keep it, converting never touches it. The reason to make a copy in another format is that ZIP is universal but compresses less tightly than the formats built for the job.
