ZIP Extractor
Open and extract ZIP archives entirely in your browser. Files are decompressed locally and never leave your device — including encrypted archives, which are unlocked with the password you provide.
Drop a ZIP to extract
or choose a ZIP — nothing is uploaded
Standard ZIP & ZIP64. Encrypted ZIPs need a password.
Everything happens in your browser. Nothing is uploaded. Chinese filenames from legacy archives (GBK) are detected automatically.
How to use
- Drop a ZIP file into the box or click “Choose ZIP”.
- Review the file list. If the archive is encrypted, enter its password.
- Download individual files, or grab everything as one new ZIP.
Details
This tool reads ZIP and ZIP64 archives locally and lets you extract individual files or re-pack everything into a new ZIP. Standard “deflate” and stored (uncompressed) entries are supported.
Encrypted archives use your password to decrypt in-browser. As a safety measure, the tool caps archive size, entry count, and decompressed size so that malformed or malicious archives cannot exhaust your browser's memory.
FAQ
Are my files uploaded anywhere?
No. Extraction runs entirely in your browser with zip.js. No file data or password is ever sent to a server.
Can it open password-protected ZIPs?
Yes. Standard ZipCrypto and AES-128/192/256 encrypted archives are supported. Just enter the password when prompted.
Why are some Chinese filenames garbled?
Older archives often store non-ASCII names in the legacy GBK encoding. This tool detects and decodes GBK filenames automatically.
What are the size limits?
Up to a 200 MB archive, 2,000 entries, and 512 MB decompressed in total. These guard against oversized or malicious “zip bomb” files.
