GZip Compressor
Compress and decompress text with gzip, deflate, or deflate-raw
About
Compress text into gzip, deflate, or deflate-raw and decompress it back, using the browser's native CompressionStream/DecompressionStream. Output is base64-encoded and the compressed size and ratio are shown. Everything runs locally; nothing is uploaded.
About this tool
Compress and decompress text with Gzip, Deflate, or Deflate-raw directly in your browser. See compression ratio and copy Base64 output. GZip Compressor runs in the browser on DevTools. There is no signup, and your input stays on this device unless the tool explicitly performs a live network lookup.
What this tool does not do
- GZip Compressor is a free in-browser utility, not a hosted API. It does not keep server-side history and is not a substitute for production verification in your own stack.
