What this file tool does
Decompresses an actual GZIP stream locally and returns the decoded bytes, rather than merely removing the .gz extension.
The selected file stream passes through DecompressionStream('gzip'); malformed headers, CRC failures, and truncated streams surface as errors.
Your selected files stay in this browser session. Requires DecompressionStream support. A GZIP stream normally contains one file and may not preserve the original MIME type.

Frequently asked questions
How can I use gzip file decompressor without uploading files?
Choose the requested files in this page and run the tool. Processing happens in your browser, and only the result you download leaves the page.
What does the downloadable restored binary file contain?
It contains the actual result or evidence produced from the selected file bytes and metadata, with the important findings shown on screen as well.
Can I use gzip file decompressor on a large file?
Browser memory and device speed set the practical limit. Start with a smaller sample if the file is several gigabytes or the device has limited memory.
Does this tool change my original files?
No. Browser file access is read-only here. The tool creates a separate result for download and does not overwrite the selected originals.
Is a clean result a complete security guarantee?
No. The result covers the checks described on this page. Use specialized desktop or forensic software when you need deeper validation.
