How to Decompress Zstandard Data - Step by Step Guide

Step 1

Paste Compressed Data

Start by pasting your Zstandard compressed data (Base64-encoded) into the input area. The tool accepts compressed data from network monitoring, telecom systems, or any Zstd-compressed source.

•
Paste compressed data: Copy your Base64-encoded Zstandard data directly into the editor
•
Upload a file: Load compressed data from a .txt or .zst file
•
Try samples: Click sample buttons to see different sizes (small, medium, large compressed data)

Example: Base64 Zstandard Compressed Data

Here's what compressed data looks like:

Step 2

Click Decompress Button

Click the blue "Decompress" button to send your Zstandard data to our C# backend API for decompression. The tool uses ZstdSharp to restore your data to its original format with fast decompression speed.

•
Fast decompression: Zstandard decompresses 3-4x faster than gzip
•
Lossless: Original data is perfectly restored without any loss
•
RFC 8878 compliant: Industry standard Zstandard decompression
•
Statistics: View compressed size, decompressed size, and expansion ratio

Example: Decompressed Output

The original data after decompression:

{
  "operator": "GlobalTel Networks",
  "country": "USA",
  "latitude": 37.7749,
  "longitude": -122.4194
}
Step 3

Copy or Download Result

Copy the decompressed data to your clipboard or download it as a text file for use in your applications, analysis tools, or data processing pipelines.

•
Copy to clipboard for immediate use in your application
•
Download as .txt file for storage or further processing
•
View statistics: Check expansion ratio and size information

What is Zstandard Decompression?

Zstandard (Zstd) decompression is the process of restoring compressed data back to its original form. Developed by Facebook, Zstandard offers exceptionally fast decompression speeds while maintaining excellent compression ratios, making it ideal for real-time data processing.

Zstandard decompression is essential for network monitoring, telecom data processing, database exports, and any scenario where quick access to compressed data is needed. You can also use our Zstandard Compressor to compress your data.

Frequently Asked Questions

What format does the decompressor accept?

The decompressor accepts Base64-encoded Zstandard compressed data. This is the standard format for transmitting binary compressed data over text-based protocols and APIs.

Is Zstandard decompression faster than gzip?

Yes! Zstandard decompression is typically 3-4x faster than gzip while providing similar or better compression ratios. This makes it ideal for real-time applications and large-scale data processing.

Can I decompress files larger than 10MB?

Yes, the tool can handle files of various sizes. However, very large files (over 10MB compressed) may take longer to process. For optimal performance, we recommend processing files in smaller chunks when possible.

Is my data secure during decompression?

Yes! All decompression happens through secure API calls. We don't store or log your data. The data is processed in memory and immediately discarded after decompression.

Is the Zstandard decompressor free?

Yes, completely free with no limitations. No registration required. Check out our other free tools like Zstandard Compressor and JSON formatter.
