7Z to ZIP

Converting a 7z to a ZIP means unpacking the .7z container, normally packed with LZMA2, and rewriting its files as DEFLATE-compressed ZIP entries; both halves run in your browser rather than on a server. Open a .7z archive right in your browser, extract the files, and download them — or repackage everything into a standard .zip. No 7-Zip, no installs, no uploads, no sign-up.

    How to convert a 7z to a ZIP

    Drag your archive onto the box above or click it to pick a .7z file. The tool opens the archive in your browser using a built-in 7z decoder, lists every file with its size, and lets you save any file on its own or choose Download as .zip to repackage the whole archive into a standard ZIP that opens natively on Windows and macOS.

    The decoding runs on your own machine: the .7z is handed to libarchive, compiled to WebAssembly and driven from a background worker so the page stays responsive, with nothing to upload and no software to install. One thing worth knowing: the rebuilt archive uses ZIP's DEFLATE compression rather than 7z's LZMA2, so the .zip usually comes out a little larger than the .7z it replaced.

    That worker pulls roughly 1 MB of WebAssembly from this site, and that decoder is the only thing this page ever requests. The honest test takes a few seconds: open your browser's network panel, drop in a .7z, and read the list. Every request is for the decoder; your archive is not among them, because at no point does the tool send your data anywhere. With the decoder already cached, a conversion runs with the network turned off.

    No file size limit is imposed here either, since there is no upload and no server quota. The .7z, each file lifted out of it, and the ZIP being assembled all sit in memory at once, so what actually caps you is the free RAM on your device rather than a stated number: budget roughly the uncompressed size of the archive plus the size of the .zip being written. Hundreds of megabytes are comfortable in a desktop browser; an older phone gives out earlier.

    Working with another format? Convert a RAR to ZIP, or open a ZIP or .tar.gz archive.

    Frequently Asked Questions

    How do I convert a 7z to a ZIP?
    To convert a 7z archive to a ZIP, drop your .7z file onto the box above or click to choose it. The tool opens the archive in your browser, lists the files inside, and lets you download them individually or choose Download as .zip to repackage everything into a standard ZIP. Nothing is uploaded to a server.
    Can I open a 7z file without 7-Zip installed?
    Yes, the LK Forge 7z to ZIP converter opens .7z files without 7-Zip. It reads 7z archives directly in your browser using a built-in decoder, so you do not need 7-Zip, WinRAR or any other software. It works on Windows, macOS, Linux, Android and iOS.
    Is it safe to open my 7z here?
    Yes, the 7z to ZIP converter is safe for private archives. There is no server side to this tool at all. The .7z is opened by a WebAssembly decoder in a background worker inside your browser, and every extracted file stays in your device's memory until you download it or press Clear.
    Is there a file size limit?
    No, the 7z to ZIP converter imposes no limit of its own. There is no cap, because nothing is uploaded and there is no server quota. The .7z, each file lifted out of it, and the ZIP being assembled all sit in memory at once, so what actually limits you is the free RAM on your device: budget roughly the uncompressed size of the archive plus the size of the .zip being written. Hundreds of megabytes are comfortable in a desktop browser; an older phone gives out earlier.
    Does the 7z to ZIP converter work offline?
    Yes, the 7z to ZIP converter works offline once the decoder is cached in your browser. The only thing this tool requests is roughly 1 MB of WebAssembly from this site; your archive is never among the requests. Open your browser's network panel, drop in a .7z, and read the list for yourself. With the decoder already cached, a conversion runs with the network turned off.
    Does it support password-protected 7z files?
    No, the 7z to ZIP converter does not support encrypted archives. The tool tests the archive for encrypted data before extracting and stops with a message if it finds any, rather than prompting for a password, so AES-encrypted 7z archives cannot be opened here. Unencrypted .7z files convert normally.
    Will the ZIP be bigger than the original 7z?
    Usually, yes: a ZIP converted from a 7z comes out somewhat larger than the original. A .7z is normally packed with LZMA2, while the ZIP this tool writes uses DEFLATE, which compresses less tightly. The trade-off is that a ZIP opens natively on Windows and macOS with no extra software.
