7z converter

A 7z archive repacks to ZIP in your browser, so its contents never leave your device. The files are read and rezipped locally, free.

What is 7z?

7z is the 7-Zip archive format, prized for compressing smaller than ZIP thanks to its LZMA algorithm. The catch is reach: opening a .7z usually means installing 7-Zip, since most operating systems unzip ZIP out of the box but not 7z. Repacking to ZIP keeps the contents and drops the dependency.

Common questions about 7z

What is a 7z file?
7z is the archive format of the 7-Zip tool. It typically uses LZMA or LZMA2 compression, which often packs files smaller than ZIP, which is why it is popular for distributing large downloads. The trade-off is that 7z is not natively openable on most systems without installing 7-Zip or a compatible tool, so a 7z archive can be awkward to share with someone who does not have that software.
How do I convert a 7z file to ZIP, and does it upload?
hushvert converts 7z TO ZIP entirely in your browser. The 7z archive is read with a WebAssembly build of libarchive, its contents are extracted locally, and a new ZIP is written on your device. Nothing is uploaded. You can verify this in the Network tab or in airplane mode on the /privacy-proof page. This client-side conversion is free and unlimited with no account.
Can hushvert create a 7z file or extract one into loose files?
No. 7z is only a source format here: hushvert repacks a 7z archive INTO ZIP. It does not produce new 7z archives, and it does not extract a 7z into individual loose files for download. The single supported job is 7z to ZIP, which keeps the contents bundled but in a universally openable wrapper.
Will my files be smaller after converting 7z to ZIP?
Usually no, often the opposite. 7z's LZMA compression is typically tighter than ZIP's DEFLATE, so the ZIP can come out larger than the original 7z. The point of this conversion is compatibility, not shrinking: you trade some of 7z's compression efficiency for a ZIP that opens everywhere without extra software. The files inside are preserved exactly.
Are encrypted or password-protected 7z archives supported?
Password-protected 7z archives are not something this repack can open, since unlocking them requires the password and decryption step that the in-browser reader does not prompt for. For an ordinary, unencrypted 7z the conversion to ZIP runs cleanly and locally on your device. If a 7z is encrypted, decrypt it with 7-Zip first, then convert the result.
