Is my 7Z file uploaded anywhere?

No — extraction runs entirely inside your browser using a real 7-Zip build compiled to WebAssembly.

Does this support password-protected 7Z files?

No — encrypted 7Z archives aren't supported by this tool.

How is this different from a fake or partial 7z reader?

This runs the actual 7-Zip 24.09 codebase compiled to WebAssembly, not a reimplementation — it handles 7Z's LZMA/LZMA2 compression exactly as the real desktop application would.

Why does the download come as a ZIP instead of loose files?

Browsers can't save a folder structure directly to disk — bundling everything into one ZIP is the practical way to deliver multiple extracted files in one download.

Can I convert the 7Z to a different archive format instead?

Yes — use the Archive Format Converter tool if you want to repackage the contents as ZIP or TAR instead of just extracting them.

Need to use 7Z Extractor right now?

7Z is a popular archive format prized for its strong compression ratio, produced by the 7-Zip application, but it has no native support in Windows Explorer, macOS Finder, or most browsers. This tool extracts a 7Z archive's contents entirely in your browser using a real 7-Zip build (version 24.09) compiled to WebAssembly — the actual 7-Zip engine, not a reimplementation.

About 7Z Extractor

Because this runs the genuine 7-Zip codebase, it correctly handles 7Z's LZMA and LZMA2 compression methods (the format's standard, high-ratio compression algorithms) exactly as the desktop application would, with no compatibility gaps.

Every extracted file lists its name and size, and everything bundles into a single ZIP for download — a more universally recognized format than leaving files loose in your downloads folder.

Everything runs locally inside your browser's WebAssembly sandbox — the archive is never uploaded to a server, and extraction happens entirely on your device.

How it works

Upload your 7Z file. Its contents are extracted automatically.
Review the file list. See every extracted file's name and size.
Download all as ZIP. Every extracted file bundled into one download.
