Compress text using Gzip or decompress Gzip data. All processing happens locally in your browser. Built for developers and technical teams who need fast, accurate, repeatable workflows.
Gzip is a widely-used data compression algorithm based on DEFLATE. It's commonly used to compress web content, reducing file sizes for faster transfer over networks. Most web servers and browsers support Gzip compression.
This tool uses the native CompressionStream API in modern browsers for efficient compression and decompression. The output is base64-encoded for easy copying and sharing.
Enter or paste text to compress, or base64 gzip to decompress.
Select Compress or Decompress mode.
Click the process button and copy or download the result.
