Download TGZ
Download your new TGZ file immediately. Multiple outputs pack into a single ZIP archive.
Why convert GZ to TGZ
GZ is a GZIP compressed file known for fast, widely supported single-stream compression. TGZ is preferred when source drops, releases, and cross-platform project bundles. This GZ to TGZ 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 TGZ, but you only have GZ.
- You are optimizing for source drops, releases, and cross-platform project bundles instead of staying in GZ.
- Recipients or tools unpack TGZ more reliably than GZ, or you need a different compression trade-off.
Good to know
- Output characteristics follow TGZ: packs a whole directory tree into one compressed download.
- Source quirks still apply — GZ is limited by typically wraps one stream rather than a rich multi-file UI, 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 GZ to TGZ
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.
