--- title: "7Z to ZIP Converter — Private, No Upload | Compress Pro" description: "Convert 7Z archives to ZIP in your browser — nothing to install, nothing uploaded. Password-protected 7Z files work too. Free, fast and private." canonical: https://compress-pro.com/7z-to-zip --- # Convert 7Z to ZIP. > Turn 7Z archives into ZIPs that open everywhere, locally. 7Z compresses harder, but plenty of computers cannot open it without extra software. Drop a 7Z, get a ZIP with the same files and folders — every machine from the office PC to a locked-down work laptop opens it natively. **The whole conversion runs in your browser**. **No uploads · No ads · Free & open source.** ## How it works 1. Drop files anywhere on the page, click to browse, or paste with Ctrl/⌘ + V. 2. Pick a quality or preset — or set an exact target size and let the tool find it. 3. Compress, compare before/after, and download — individually or as a ZIP. ## When to keep 7Z instead If everyone involved has 7-Zip, keep the 7Z — it is the better compressor. Convert to ZIP when the recipient is unknown, the file goes to a web form that only accepts .zip, or an old tool chokes on 7Z. The reverse trip lives at [ZIP to 7Z](https://compress-pro.com/zip-to-7z); creating fresh archives from loose files is the [archive tool](https://compress-pro.com/zip-files). ## Frequently asked questions ### Will the ZIP be bigger than my 7Z? Usually a little — 7Z (LZMA2) compresses tighter than ZIP (deflate). For already-compressed content like photos or video the difference is a rounding error; for text and code expect the ZIP to grow some percent. That is the price of a format everything can open. ### Do encrypted 7Z archives work? Yes — enter the password and the archive decrypts locally, including 7Z files with encrypted file lists (-mhe). The resulting ZIP is unencrypted by design, so the recipient does not need the password. ### Does the folder structure survive? Fully. The 7Z is unpacked in memory and the same tree is rebuilt inside the ZIP — nested folders, names and paths stay exactly as they were. ### Is it private? Yes. Archives are built and converted entirely in your browser — neither the archive nor the files inside it are ever uploaded, and any password you set is applied locally. The server does nothing but deliver this page. Want proof? Run one file through, switch your connection off, and run another — it still works. ## Related tools - [Convert ZIP to 7Z](https://compress-pro.com/zip-to-7z) - [Convert RAR to ZIP](https://compress-pro.com/rar-to-zip) - [Zip & Unzip files](https://compress-pro.com/zip-files) --- Part of [Compress Pro](https://compress-pro.com/) — every tool page has a markdown twin at `.md`.
