Why use this tool?
Testing how applications handle corrupted or invalid files is essential for building robust software. This tool generates files with random byte patterns that simulate data corruption.
- Error handling tests — Verify your app gracefully handles invalid files.
- Recovery testing — Test data recovery and backup systems.
- Security testing — Ensure file validators properly reject malformed files.
- Privacy-focused — All generation happens in your browser. No data is stored or transmitted.
