How to Unzip GZIP Files - Complete Guide

Step 1

Select Your GZIP File

Choose the GZIP file you want to unzip. GZIP uses the GZIP file format specification:

•
Upload from computer: Click "Upload" and browse to your .gz or .gzip file
•
Paste compressed data: Copy and paste base64-encoded GZIP data directly
•
Test with sample: Click "Sample" button to see how the tool works

Example: Compressed GZIP Input

Here's what compressed GZIP data looks like in base64 format:

H4sIAAAAAAAAA6tWyk0tSU1RslJQSssvysxLt1VKS8wpTtVRyE9TqgUA...

This base64-encoded GZIP compressed file will be unzipped to reveal the original content.

Step 2

Extract the File

The tool automatically unzips your GZIP file using the DEFLATE algorithm as soon as you upload it:

•
Automatic extraction: File is unzipped instantly in your browser
•
No server upload: All processing happens locally for privacy
•
Preview content: See extracted content immediately in the output panel

Example: Extracted Output

After unzipping, the original data is extracted:

{
  "application": "DataSync Enterprise",
  "version": "2.8.0",
  "modules": [
    "API Gateway",
    "Data Pipeline",
    "Analytics Engine"
  ]
}

The extracted content is now readable and ready to use!

Step 3

Save Your Extracted File

Save or use your unzipped content:

•
Download file: Click "Download" to save the unzipped content as a text file
•
Copy text: Use "Copy" button to copy content to your clipboard
•
Further processing: Use with other tools like JSON Formatter

Frequently Asked Questions

How do I unzip a .gz file?

Simply click the "Upload" button and select your .gz file. The tool will automatically extract and display the contents. You can then download the unzipped file or copy its contents to your clipboard.

Is GZIP unzip the same as gunzip?

Yes, unzipping GZIP files and using gunzip are the same process. "gunzip" is the Unix/Linux command-line tool, while "unzip" is a more general term for extracting compressed files. Both extract the original file from GZIP compression.

Can I unzip .tar.gz files?

This tool extracts the GZIP compression layer. For .tar.gz files, you'll get a .tar file after unzipping, which you'll need to extract separately using a TAR tool. GZIP only handles the compression, not the archive format.

Is this GZIP unzip tool secure?

Absolutely. All file extraction happens entirely in your web browser using JavaScript. Your files never get uploaded to any server, ensuring complete privacy and security for sensitive data.

What file types can be inside a .gz file?

GZIP can compress any type of file - text files, JSON, XML, CSV, logs, configuration files, and more. The tool will extract whatever was originally compressed, maintaining the original format.

Do I need to install software to unzip GZIP files?

No installation required! This is a web-based tool that works directly in your browser. No downloads, no registration - just upload and unzip instantly. For programming, use Python's gzip or Node.js zlib.
