About This Tool
What is File Zip / Unzip?
A tool for compressing files into ZIP, GZIP, or TAR.GZ archives, or extracting files from compressed archives. All processing happens in your browser, so files are never uploaded to a server, ensuring privacy and security.

Frequently Asked Questions
What is the difference between ZIP, GZIP, and TAR.GZ?▼
ZIP is an archive format that compresses and bundles multiple files together. GZIP compresses a single file only. TAR bundles files without compression, so TAR.GZ (or .tgz) first bundles with TAR then compresses with GZIP. ZIP is most common on Windows; TAR.GZ is standard on Linux/macOS.
Is there a file size limit for browser-based compression?▼
Yes, browser memory limits apply. Most browsers can handle files up to several hundred MB, but very large files (1GB+) may cause the tab to crash or run very slowly. For large files, desktop tools like 7-Zip are more reliable. The exact limit depends on your device's available RAM.
Are my files uploaded to a server during compression?▼
No. All compression and decompression happens entirely in your browser using JavaScript. Your files never leave your device. This means it works offline and your data remains completely private.
