Frequently Asked Questions
Technical answers regarding format compatibility, privacy, security, and large archive handling.
1What archive formats does the extractor support?
The tool opens ZIP, RAR, 7Z, TAR, GZIP, and BZIP2 archives, including split volumes and ZIP64 extensions.
2Are my files uploaded to a server during extraction?
No. All processing occurs in your browser using WebAssembly; no archive data leaves your device.
3Can I extract password-protected archives?
Yes. Enter the password when prompted; decryption happens locally for ZIP and RAR encrypted entries.
4Is there a file size limit for extraction?
The only limit is available browser memory; ZIP64 archives larger than 4 GB are fully supported.
5Does the archive extractor work on mobile browsers?
Yes, our archive extractor works fully in mobile browsers (iOS Safari, Chrome Android). All extraction runs locally on your device — no app installation required.
6Can I extract multiple archives at the same time?
You can extract multiple archives sequentially. Each archive is processed independently in your browser with complete privacy.
7How can I extract ZIP files without installing software?
Our ZIP Extractor runs entirely in your browser using client-side JavaScript. You can upload any standard ZIP archive, explore its file directory ledger, preview images or text contents, and decompress individual files directly to your device without installing third-party tools.
8Is my uploaded archive secure?
Yes, it is 100% secure. Since all extraction and rendering operations happen directly within your browser's private memory space (client-side), no files or data ever cross the network to any servers. This makes it completely safe for confidential and sensitive data.
9What types of files can I preview before extracting?
You can preview common image files (PNG, JPG, SVG, WebP, GIF, ICO) and text/code files (HTML, CSS, JS, JSON, XML, TXT, MD, YAML) in browser memory before extracting or downloading them.
10Does it support large ZIP archives?
Yes. The extractor uses local memory and processing power to scan and decompress files. We recommend archives under 1GB for optimal speed, responsiveness, and to prevent browser tab out-of-memory limits.
