How to convert TAR to GZ
- Step 01
Add your TAR file
Drop one or many TAR files onto the converter, or browse from disk. Stay within the on-device size limits shown under the drop zone — oversized files are rejected so your tab does not freeze.
- Step 02
Repack locally
Extract and rebuild the archive as GZ in your browser. Folder trees stay on this device throughout the conversion.
- Step 03
Download GZ
Download your new GZ file immediately. Multiple outputs pack into a single ZIP archive.
Why convert TAR to GZ
TAR is a uncompressed tape archive known for preserves file trees without proprietary packaging. GZ is preferred when compressing a payload or tar stream for transfer. This TAR to GZ converter unpacks and repacks entirely in your browser, so installers, backups, and shared folders never upload to a remote archive service.
When to use this tool
- A tool, form, or teammate asked for GZ, but you only have TAR.
- You are optimizing for compressing a payload or tar stream for transfer instead of staying in TAR.
- Recipients or tools unpack GZ more reliably than TAR, or you need a different compression trade-off.
Good to know
- Output characteristics follow GZ: fast, widely supported single-stream compression.
- Source quirks still apply — TAR is limited by no compression on its own — often paired with gzip, and conversion cannot invent missing data.
- Password-protected or damaged archives may fail to open; encryption is not re-applied on output unless the format requires it.
- Browser limit: about 100 MB compressed, up to 20 files per batch, and roughly 500 MB / 500 entries once extracted.
- Need a bigger file? For multi‑GB archives, use 7-Zip, WinRAR, PeaZip, or your OS archive utility — they stream to disk instead of holding everything in a browser tab.
File size limits for TAR to GZ
Browser limit: about 100 MB compressed, up to 20 files per batch, and roughly 500 MB / 500 entries once extracted.
Why there is a limit
Archives are fully extracted into memory before repacking. Zip bombs and huge ISO/RAR payloads can crash the tab, so compressed and uncompressed caps keep the process safe on-device.
If your file is too large
For multi‑GB archives, use 7-Zip, WinRAR, PeaZip, or your OS archive utility — they stream to disk instead of holding everything in a browser tab.
