Why use a “Corrupt My File” Tool?
Many systems fail when dealing with broken or incomplete files. To build strong and secure applications, engineers need a controlled way to produce corrupted data.
This online file corrupter helps software developers, testers, data engineers, and IT security professionals simulate real-world damage conditions:
- Test upload validation systems
- Check backup & recovery behavior
- Force error-handling workflows
- Simulate damaged file attacks safely
- Build stronger application resilience
Supported File Types
This tool corrupts any file you upload, including:
- Documents: PDF, DOC, DOCX, TXT
- Spreadsheets: XLS, XLSX, CSV, JSON
- Archives: ZIP, RAR, 7Z
- Images: JPG, PNG, GIF, BMP
- Audio/Video: MP3, WAV, MP4, MOV
