Frequently Asked Questions
Is this tool safe?
Absolutely safe. All file processing occurs locally in your browser, our servers never receive or store your files.
What file types are supported?
Supports any file type, including documents, images, videos, audio, archives, etc. File size should not exceed 100MB for optimal performance.
Can corrupted files be recovered?
This depends on the corruption level and file type. Light corruption may be partially recoverable, heavy corruption is usually unrecoverable. Please ensure you backup original files.
Is this tool free?
Yes, completely free. We don't charge any fees and don't require account registration.
How does the corruption process work?
The tool randomly modifies bytes in your file based on the corruption level you select. Light mode changes 1% of bytes, medium 5%, and heavy 15%. This simulates real file corruption scenarios for testing purposes.
Which browsers are supported?
All modern browsers are supported including Chrome, Firefox, Safari, and Edge. We recommend using the latest version for best performance. Your browser must support modern JavaScript features.
What's the maximum file size?
For optimal performance, we recommend files under 100MB. Larger files may take longer to process and could slow down your browser. Very large files might cause performance issues depending on your device.
Can I corrupt multiple files at once?
Currently, the tool processes one file at a time to ensure optimal performance and reliability. You can repeat the process for each file you need to corrupt.
Is my data really private?
Yes, absolutely. All processing happens locally in your browser using JavaScript. Your files never leave your device - they're not uploaded to any server. We have no way to access your files.
What are common use cases for this tool?
Common uses include testing data recovery software, validating backup systems, educational demonstrations, research on file integrity, and system administration testing. Always ensure you have proper authorization and backups.
How can I recover corrupted files?
Recovery depends on the corruption level and file type. Professional data recovery software may help with lightly corrupted files. However, corruption is designed to be permanent, so always keep backups of your original files.
What technology powers this tool?
Built with Next.js 14, TypeScript, and TailwindCSS. All file processing uses client-side JavaScript with the Web APIs. No backend servers are involved in file processing.
