❓ Frequently Asked Questions
Is it safe to use an online ZIP tool?
Our tool is completely safe because it processes everything in your browser. Unlike other online tools that upload your files to servers, our tool uses advanced JavaScript technology to create and extract ZIP files directly on your device. Your files never leave your computer, ensuring complete privacy and security.
What is a ZIP file and why should I use it?
A ZIP file is a compressed archive that can contain one or more files and folders. ZIP files reduce file sizes through lossless compression, making them perfect for: saving storage space, sending multiple files via email, organizing project files, creating backups, and distributing software or documents.
Do I need WinZip or WinRAR to use this tool?
No! Our browser-based tool is a complete alternative to desktop software like WinZip, WinRAR, or 7-Zip. You don't need to install any software or purchase licenses. Simply open your web browser and start creating or extracting ZIP files immediately.
What's the difference between ZIP, RAR, and 7z files?
ZIP is the most universal format, supported by virtually all devices and operating systems. RAR offers better compression but requires specific software. 7z provides the best compression but has limited support. For maximum compatibility and ease of use, ZIP is the best choice for most users.
Are there any file size limitations?
Unlike many online ZIP tools that impose strict file size limits (often 10-50MB), our tool has no artificial restrictions. The only limit is your browser's available memory. You can create and extract large ZIP files containing gigabytes of data, all processed securely in your browser.
Can I create password-protected ZIP files?
Currently, our tool focuses on standard ZIP creation and extraction. For password-protected archives, we recommend using desktop software like 7-Zip (free) or the built-in compression tools in Windows/macOS. We may add encryption features in future updates based on user demand.
Which browsers are supported?
Our tool works on all modern browsers including Chrome, Firefox, Safari, and Edge. We use standard web technologies (JavaScript and Web APIs) that are supported across all major browsers and operating systems including Windows, macOS, Linux, Android, and iOS.
