Why use ZipZip for File Extraction?
Military-Grade Privacy
Unlike other online converters, we never see your files. Processing happens in your browser's sandbox memory, leaving no digital footprint on any server.
WASM Performance
Leveraging WebAssembly (WASM), ZipZip achieves near-native speeds for decompressing .7z, .rar, and .zip formats, significantly faster than traditional JS tools.
No Installation
Open archives on Chromebooks, mobile devices, or locked-down office computers without installing WinRAR or 7-Zip software. It just works.
Technical Specifications
ZipZip utilizes a custom build of 7-Zip libraries compiled to WebAssembly. This allows your browser to function as a full-featured archiver.
Algorithm
LZMA, LZMA2, PPMd
Encryption
AES-256 (Local)
RAR Version
RAR4, RAR5 Support
File System
Virtual Blob Storage
The Problem with Traditional Cloud Unzippers
Most "Online Unrar" websites act as a proxy. When you click upload, your document which could contain private financial data, passwords, or personal photos is sent to a remote server located in an unknown jurisdiction. Once the file is on their disk, you lose control over who sees it or how long it is stored.
ZipZip solves the privacy paradox. By moving the heavy computation to the client side (your browser), we eliminate the need for data transfer. Your internet connection is only used to load our app once; after that, you could technically disconnect from the web and continue extracting files. This is the future of secure utility computing.
Comprehensive Support for All Major Archive Formats
ZipZip is designed as a universal solution for users who need to manage archives on the go. Whether you are dealing with a .7z (7-Zip) file known for its high compression ratio, or a classic .zip archive used across all operating systems, our tool handles them with ease. We also provide full support for RAR4 and RAR5, ensuring that even the most recent WinRAR archives can be accessed without proprietary software.
Why Local Extraction is the Standard for 2026
The digital landscape has shifted. Sending data to a server for "processing" is now considered a security risk. By utilizing Client-Side WASM technology, ZipZip ensures that your data remains in a "zero-knowledge" environment. Your browser performs the heavy lifting, which means your sensitive documents, private backups, and project files are never exposed to middle-man attacks or server-side logging.
