Overview

The Text Data Decompressor is a powerful utility designed to restore compressed text strings to their original, readable format using industry-standard algorithms like RLE, LZ77, and Huffman decoding.

When to Use

  • •When you need to restore text that was compressed using Run-Length Encoding (RLE) or LZ77 algorithms.
  • •When you have encoded data strings that require Huffman decoding to reveal the original content.
  • •When you need to quickly decode Base64 or Hex-encoded compressed data back into plain text.

How It Works

  • •Paste your compressed text into the input field.
  • •Select the appropriate decompression algorithm from the dropdown menu, or enable 'Auto-Detect' to let the tool identify the format.
  • •Specify the input encoding (Raw, Hex, or Base64) to ensure the tool interprets the data correctly.
  • •Provide any necessary auxiliary data, such as a Huffman tree, if required by the specific algorithm, and click to decompress.

Use Cases

Restoring log files or configuration data that were compressed to save storage space.
Decoding data payloads received from legacy systems that utilize RLE or LZ77 compression.
Reconstructing text from Huffman-encoded data streams for analysis or debugging.

Examples

1. Restoring RLE Compressed Logs

Background
A system administrator has a log file containing repetitive character sequences compressed via RLE to reduce file size.
Problem
The log file is unreadable in its current compressed state.
How to Use
Paste the RLE-compressed string into the tool, select 'Run-Length Encoding (RLE)' as the algorithm, and set input encoding to 'Raw'.
Outcome
The tool expands the compressed sequences, restoring the log file to its original, human-readable format.

2. Decoding Huffman-Encoded Data

Background
A developer is working with a data stream that uses Huffman coding to optimize transmission bandwidth.
Problem
The raw data appears as a series of bits that cannot be interpreted without the decompression tree.
How to Use
Paste the encoded data, select 'Huffman Decoding', and provide the required tree data in the 'Decompression Data' field.
Outcome
The tool maps the bit sequences back to the original characters, providing the decoded text output.

FAQ

Does this tool support all compression formats?

It supports common algorithms including RLE, LZ77, Huffman, and Base64 decoding.

What should I do if the auto-detect feature fails?

If auto-detection fails, manually select the specific algorithm used during the compression process.

Is Huffman decompression always possible?

Huffman decompression requires the original tree data or mapping table used during compression to successfully reconstruct the text.

Can I decompress Hex or Base64 encoded strings?

Yes, select the corresponding 'Input Encoding' option to ensure the tool decodes the format before applying the decompression algorithm.

Is my data stored on your servers?

No, all decompression processes are performed locally in your browser to ensure your data remains private.
