Unzip files online: drop a ZIP and its contents appear as a folder tree you can browse before extracting anything, then save the one file you were after, tick a handful, or take everything. That helps when a ZIP is too big to unpack just to find one document, when you’re on a borrowed or locked-down computer, or when you want to check what an archive holds before it lands in your downloads. Most ZIPs are read by a small built-in reader with no extractor to download, entirely on your device, so nothing is uploaded. Clutter such as __MACOSX folders, .DS_Store and Thumbs.db is hidden by default. The same free unzip tool also opens RAR, 7z, TAR and .tar.gz files.
How it works
- Drop the .zip file. Its entries are read from the ZIP’s own index without decompressing anything, with the total size and the number of hidden files shown.
- Expand folders, Peek at images and text files, and tick what you want. A password-protected entry is marked locked and can’t be ticked.
- Press Save on a single file, or Extract → ZIP to pull a subset into a smaller ZIP; with nothing ticked, the button takes everything.
Questions
- Can I unzip just one file from a large ZIP?
- Yes, and only that file is decompressed. Find it in the tree and press Save on its row: it downloads under its own name, without the folders above it, because a browser download can’t create folders. Peek shows an image, or the first 100 KB of a text file, before you decide to save it.
- What are the hidden files in my ZIP?
- Leftovers that archivers add and almost nobody wants: the __MACOSX folder and .DS_Store files from macOS, Thumbs.db from Windows Explorer, and other dotfiles. They are listed behind the Show hidden option rather than deleted, and extracting to a ZIP skips them, so the result holds only your own files.
- Is there a size limit for unzipping?
- Extracting to a ZIP is capped at 2 GiB of uncompressed output, checked before the run starts rather than failing halfway. Above that, save files one at a time with Save. Everything is held in your browser’s memory while it works, so very large archives also depend on how much memory your device has.
- Does my file get uploaded?
- No. The models and all processing run inside your browser on your own device. You can verify this yourself: open your browser’s DevTools, watch the Network tab, and process a file: there are no uploads. After the first visit most tools also work fully offline.
- Are password-protected archives supported?
- Encrypted ZIP entries and password-protected RAR/7z archives are detected and reported honestly. A password prompt is on the roadmap, but nothing is silently skipped today.
- Why RAR and 7z but ZIP output only?
- Reading RAR and 7z uses the open libarchive project. Writing RAR is proprietary to WinRAR, and 7z output has little reason to exist here, since ZIP opens on every device without extra software.
