How to: Create TAR.GZ
- Select files or a whole folder.
- Pick .tar.gz, .tar.xz, .tar, .tar.bz2 or .7z and name the archive.
- Click Start and download the archive.
TAR.GZ is the archive format servers, Linux distributions and developer tools expect. Fileopia builds one in your browser – handy on Windows, ChromeOS and phones where you can’t run the tar command – without uploading a byte.
Common uses
- Package website files or a project for upload to a Linux server.
- Send logs or a folder of files as a single attachment.
- Create backups in an open, long-lived format.
- Prepare .7z archives for maximum compression.
Tips for best results
- Already-compressed files (JPG, MP4, ZIP) barely shrink – choose plain .tar for them to save time.
- Use .tar.xz for text-heavy folders such as logs or source code.
- Name the archive with a date for easy backups.
TAR vs ZIP
ZIP compresses each file separately and is built into every OS. TAR bundles everything first and then compresses the whole stream, which usually yields smaller archives for many small files and keeps Unix permissions and long paths.
How it works
Your files are passed to libarchive (BSD licence) running as WebAssembly in a background worker. The compressed archive is written in memory and offered as a download. The 1 MB engine is loaded only when you press Start.

Your files never leave your device
Create TAR.GZ runs entirely in your browser using JavaScript and WebAssembly. Your files are read from your disk into this tab, processed in memory and saved straight back to your downloads folder – they are never uploaded to Fileopia or any third party.
- Test it yourself: once this page has loaded, switch off Wi‑Fi or mobile data and run the tool – it keeps working.
- Check the network: open your browser’s developer tools (F12 → Network) while processing; you will see no file upload requests.
- Nothing to delete: close the tab and the data is gone – there is no server copy, no retention period and no account.
Frequently asked questions
Which format should I pick?
.tar.gz is the universal choice for Linux, servers and developers. .tar.xz is smaller but slower. .7z gives the best compression for Windows users with 7-Zip. Plain .tar does not compress at all.
Are files uploaded?
No. The archive is built on your device with libarchive compiled to WebAssembly.
Is folder structure kept?
Yes when you choose a folder – relative paths are stored in the archive.
Can I password-protect it?
Not yet. Use Create ZIP or Protect PDF for encrypted output.
Is there a size limit?
Only your device memory – a few GB on a laptop.
Can Windows open .tar.gz?
Windows 10/11 can open .tar and .tar.gz with the built-in tar command and File Explorer (Windows 11 23H2+).
Can I extract archives too?
Yes – use Extract TAR.GZ, Extract RAR or Extract 7Z.
Why is my .tar.gz not smaller?
The files are already compressed; there is nothing left to squeeze.
Is Create TAR.GZ really free?
Yes. Every tool on Fileopia is 100% free with no file limits, no sign-up and no watermarks. The site is supported by unobtrusive ads.
Are my files uploaded to a server?
No. Fileopia processes your files directly in your browser using JavaScript. Your documents never leave your device, so they stay completely private.
Does it work on mobile?
Yes. Fileopia works in any modern browser on Android, iPhone, iPad, Windows, Mac and Linux.
