Stream Decompressor
Decode gzip- or deflate-compressed bytes to UTF-8 text using built-in browser APIs.
Files stay in your browser. We do not upload compressed blobs or decompressed text.
Decompress binary
Pick the codec that matches your payload (HTTP often uses gzip or deflate). Raw deflate streams may need deflate-raw.
Highlights
Debug HTTP bodies and saved blobs without server-side tools.
Local processing
DecompressionStream runs in your browser; files are not sent to Infyways.
Web codecs
Uses the same gzip/deflate algorithms many CDNs and HTTP clients rely on.
How to Use
Simple 2-step process
Step 1
Choose gzip, zlib-wrapped deflate, or raw deflate to match how the data was compressed.
Step 2
Upload the binary file. Output is decoded as UTF-8 text for preview.
Frequently Asked Questions
Everything you need to know about this tool and how it works.
See Full FAQThe result is interpreted as UTF-8 text. If the payload is binary (not text), use a hex editor after saving locally.
This tool uses DecompressionStream gzip/deflate modes. Brotli support varies; if you need brotli, try a desktop tool or check your browser’s latest codec support.
