Gzip Compress / Decompress

Compress text strings into Gzip Base64 or Hexadecimal compressed payloads, and decompress Gzip Base64 data back into readable plain text using native browser `CompressionStream` and `DecompressionStream` APIs.

Why Use This Tool?

• Web Optimization & Payload Testing: Test exact Gzip payload compression ratios for API payloads or HTML/CSS/JS text strings.
• Log Decompression: Decompress Gzip Base64 encoded server logs from CloudWatch or HTTP headers.
• URL Compression: Compress large text strings before storing them in URL query parameters or local storage.

How to Use

1. Select Action: "Compress Text to Gzip Base64" or "Decompress Gzip Base64 to Text".
2. Paste your plain text or Gzip Base64 string into the input editor.
3. View converted result and byte compression percentage savings.

Real Working Example

Input:

Plain Text: "The quick brown fox jumps over the lazy dog. The quick brown fox jumps over the lazy dog."
