Unzip Large Files Online

Extract large archives up to 2GB directly in your browser. No upload limits, no server timeouts, no waiting for slow uploads. Your files process locally at full speed.

The Large File Advantage

Most online extractors limit you to 50-200MB because larger files strain their servers and take forever to upload. JustUnzip processes files locally, so there's no upload at all. Your 1GB archive processes just as fast as a 10MB one - it's already on your device.

Tips for Large Files

  • Close other tabs - Free up browser memory for better performance.
  • Use Chrome or Firefox - These handle large files better than Safari.
  • Desktop preferred - Laptops and desktops have more memory than phones.
  • Check free space - You'll need space to download extracted files too.
