Open and inspect ZIP files right in your browser
Getting a ZIP you half-trust is a routine dilemma: extract it blindly and hope, or install an archiver just to peek inside. Neither is great — archives can hide executables next to innocent-looking folders, and absolute paths and symlink tricks are classic archive attacks.
The better move is inspecting first: browse the full file tree, preview text and images where they sit, then extract exactly what you want — one file, one folder, or everything. Nothing uploads anywhere; the archive is read locally in your browser.
Open the free ZIP File Viewer — no signup, runs entirely in your browser.
How to use it
- Drop the ZIP file in — it opens locally, no upload.
- Browse the directory tree and preview files in place.
- Extract a single file, a folder, or the whole archive.
Why this one
- Full file tree navigation before you extract anything.
- Selective extraction — grab one file or folder instead of unpacking everything.
- In-browser previews for text, JSON, images and more.
- Opens AES and ZipCrypto encrypted archives, and ZIP64 files over 4 GB.
Frequently asked questions
Is my ZIP file uploaded to a server?
No. The archive is parsed entirely in your browser — you can load the page, go offline, and it still works. That also makes it safe for confidential archives.
Can it open password-protected ZIP files?
Yes — both AES and ZipCrypto encryption are supported. You will be asked for the password, which is used locally to decrypt and never leaves your device.
How big an archive can it handle?
ZIP64 support means archives beyond the old 4 GB limit work. The practical ceiling is your device's memory, since the file is processed locally rather than streamed through a server.
