Convert 7z to ZIP. No 7-Zip install, nothing uploaded
7z compresses well, but many computers cannot open it without additional software. ZIP has broader built-in support. This page uses libarchive to decompress a 7z file and repackage its contents as a ZIP while preserving the folder structure. The work happens locally, so even a large archive has no upload delay. The ZIP will usually be larger because its compression is less efficient than 7z. The extra size is the cost of broader compatibility.
How it works
- Drop your .7z file below.
- It is decompressed and repackaged as a ZIP on your device.
- Download the .zip. Openable anywhere, no 7-Zip required.
Frequently asked questions
Will the ZIP be bigger than the 7z?
Usually, yes. 7z’s LZMA compression is stronger than ZIP’s deflate, so the same contents take more space as a ZIP. You are converting for compatibility. Anyone can open a ZIP, and accepting a modest size increase for it.
Is the folder structure kept?
Yes. The paths inside the 7z are recreated in the ZIP, so nested directories are preserved rather than flattened.
Do password-protected 7z files work?
No. Encrypted 7z archives are not supported in this version and will fail to convert. Decompress them with 7-Zip first, then repackage the contents here if you need a ZIP.
Is the 7z uploaded to convert it?
No. Decompression and repackaging run in your browser via WebAssembly and JavaScript. The file stays on your device, with no upload step and no transfer wait.
