Drop a .tar.gz / .tgz / .tar / .gz file here
or click to choose — decompressed on your device, never uploaded
A .tar.gz is two formats stacked: a tar bundle of files that has then been gzip-compressed as a whole, so opening one means undoing the gzip layer before the tar can be read. This extractor does both steps with your browser's own DecompressionStream. Open .tar.gz, .tgz, .tar and .gz archives right in your browser — list the files, download them, or repackage the whole thing as a ZIP. Nothing is uploaded and there's no sign-up.
Drag your archive onto the box above or click it to pick a .tar.gz, .tgz, .tar or .gz file. The tool undoes the gzip compression using your browser's built-in decompression, reads the tar bundle, and lists every file with its size. Download files one at a time, grab them all, or choose Download as .zip to convert the archive into a standard ZIP.
There is no decoder to download here at all. The gzip layer is undone by DecompressionStream, a decompression API built into your browser, and the tar bundle is unpacked by the page's own JavaScript; the optional ZIP repack uses the bundled JSZip library. Everything runs locally, so your files never leave your device. Test it if you like: load this page, turn off your Wi-Fi or switch to airplane mode, and extraction still works, because no request is made when you drop a file in.
No file size limit is set by this tool, because there is nothing to upload and no server quota to hit. The gzip layer is decompressed into a single buffer in memory and the file list points into that same buffer, so the practical ceiling is the free RAM on your device rather than a published maximum: allow about the uncompressed size of the archive, and roughly that much again if you choose Download as .zip. Archives in the hundreds of megabytes are fine in a desktop browser; an older phone runs out of memory sooner.
