Decompress a .gz file in your browser with a hard memory budget, verified against its CRC-32 and size — corrupt files are refused, not half-written.
Single-member archives are verified against their CRC-32 and ISIZE footers; multi-member ones decompress without that check.
The decompressed file appears here.
Your file is never sent to a server. It is read and processed by your own browser, and the results are not stored.
A gzip bomb expands data thousands of times. This tool streams the decompressor and counts every output byte; the moment the count crosses 512 MB the operation fails with an explanation. That is the only honest answer a browser tab can give — better to refuse than to crash.
Uncompressed output above the budget is the only failure mode that cannot be retried locally without a server; the message says so.
Every gzip trailer carries the CRC-32 of the uncompressed data and its size. This tool checks both for single-member files. If the CRC mismatches, something in the file changed between wherever it came from and you — truncation, corruption, or a hostile edit.
No. GZIP Extractor runs in your browser, and the file is read there rather than sent to a server for processing. Our host still sees ordinary page-request metadata, which is described on the privacy page.
Yes, GZIP Extractor is free, with no paid tier, no account, and no watermark added to your output. The limits are technical rather than commercial: file size, page count and supported formats are listed on this page.
GZIP Extractor supports .gz files up to 512MB directly in your browser.
Nothing leaves your device, and the decompressor has a hard memory budget. If a file would expand beyond 512 MB, the tool refuses it and tells you — an "archive bomb" cannot fill your RAM.
Single-member .gz files are verified against their CRC-32 and ISIZE footers. A truncated or corrupt file is rejected with an error instead of half-written bytes.
Decompress here to get the .tar, then open it with the TAR Extractor. Two steps, each with its own verification.
Too small to be gzip, truncated, corrupt CRC, or expanding past the budget. Each refusal shows the specific reason — the tool never "tries its best" on a broken file.
