How to Unzip ZLIB Files - Step by Step Guide

Step 1

Upload Your Compressed File

Let's get your compressed file ready to extract! Whether you have a ZLIB .zlib file or base64-encoded data using the DEFLATE algorithm (used in PNG, PDF, and Git), you have several convenient options:

Paste directly: Copy your compressed data and paste it into the input editor
Upload a file: Click "Upload" to select a .zlib file from your computer
Try the sample: Click "Sample" to load example data and see how extraction works

Example: Compressed ZLIB Input

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

This base64-encoded compressed data will be extracted to reveal the original content.

Step 2

Automatic Extraction

The extraction happens instantly! As soon as you input data, the tool automatically:

Extracts content: Unzips the compressed data back to its original form using ZLIB inflate (RFC 1950)
Validates format: Checks if the data is valid ZLIB format
Displays results: Shows the extracted content in real-time

Example: Extracted Output

After extraction, the original data is restored:

{
  "product": "CloudSync Pro",
  "version": "3.2.1",
  "features": [
    "Real-time sync",
    "256-bit encryption",
    "Cross-platform"
  ]
}

The extracted content is now readable and ready to use!

Step 3

Download or Copy Extracted Data

Get your extracted data ready for use! Multiple export options make it easy to work with your content:

Copy to clipboard: One-click copying for quick use in other applications
Download as file: Save the extracted content as a JSON or text file
Format the output: Use our formatting tools if the output is JSON or XML
