How to Use Free Online Base64 to LZ4 Decompressor - Step by Step Guide

Step 1

Input Base64 Encoded Data

Start by entering your Base64 encoded LZ4 compressed data! This tool reverses the compression and encoding process, perfect for retrieving data from APIs, reading from databases, or processing compressed JSON payloads. You have several convenient options:

•
Paste directly: Copy your Base64 encoded LZ4 data and paste it into the input editor
•
Upload a file: Click "Upload" to select a Base64 text file from your computer
•
Try the sample: Click "Sample" to load example Base64 LZ4 data and see the decompression in action

Example: Base64 Encoded Input

Here's what Base64 encoded LZ4 compressed data looks like:

BAAAAAAoeyJ1c2VyIjp7ImlkIjoiVVNSLTk4NzY1IiwibmFtZSI6IkFsZXggQ2hlbiJ9fQ==

This Base64 string contains compressed JSON data that will be restored to its original format.

Step 2

Automatic Decoding & Decompression

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

•
Decodes Base64: Converts the text-safe Base64 format back to binary data
•
Decompresses with LZ4: Ultra-fast decompression using the LZ4 algorithm
•
Shows statistics: View compressed size, decompressed size, and expansion ratio

Example: Decompressed Output

After decoding and decompression, you'll get your original data back:

{
  "user": {
    "id": "USR-98765",
    "name": "Alex Chen"
  }
}

The original JSON data is perfectly restored with all formatting intact.

Step 3

Copy or Download Decompressed Data

Use your restored data wherever you need it:

•
Copy to clipboard: One-click copying for quick use in your applications
•
Download as file: Save the decompressed data to a text file
•
Process further: Use the restored data in your web applications

Frequently Asked Questions

What is Base64 to LZ4 decompression?

Base64 to LZ4 decompression is the reverse process of LZ4 to Base64 encoding. It first decodes the Base64 text back to binary LZ4 compressed data, then decompresses the LZ4 data using the ultra-fast LZ4 algorithm to restore your original content. This is essential for retrieving data from APIs, databases, or any storage that used LZ4 Base64 encoding.

When would I need to use this tool?

You'll need this tool when receiving Base64 encoded LZ4 data from APIs, retrieving compressed data from databases, processing compressed JSON payloads, working with real-time gaming data, or any situation where data was compressed with LZ4 and encoded to Base64 for safe text transmission.

Is my data secure when using this tool?

Yes! All decoding and decompression happens entirely in your browser using client-side JavaScript. Your data never leaves your computer or gets uploaded to any server, ensuring complete privacy and security for your sensitive information.

What if I get a decompression error?

Decompression errors usually occur if: (1) The input is not valid Base64 encoded data, (2) The Base64 data is not LZ4 compressed, or (3) The compressed data is corrupted. Make sure you're using data that was created with our LZ4 to Base64 converter or a compatible LZ4 compression tool.

Can I decompress regular Base64 data without LZ4?

No, this tool is specifically for Base64 encoded LZ4 compressed data. If you have regular Base64 data (not LZ4 compressed), you'll need a standard Base64 decoder instead. This tool expects the Base64 data to contain LZ4 compressed content.

How fast is LZ4 decompression?

LZ4 decompression is extremely fast, typically 2-3x faster than GZIP decompression. The decompression happens almost instantly in your browser, making it perfect for real-time applications, gaming, and high-performance systems where speed is critical.

What types of data can I decompress?

You can decompress any text data that was originally compressed with LZ4 and encoded to Base64, including JSON, XML, CSV, plain text, log files, configuration files, and more. The tool will restore the exact original content.

Is LZ4 decompression lossless?

Yes! LZ4 is a lossless compression algorithm, meaning the decompressed data will be exactly identical to the original data, byte-for-byte. No information is lost during the compression and decompression process.
