File Corrupter
Intentionally corrupt files for testing error handling, QA, and development purposes only.
This tool is intended for legitimate testing and development purposes only. Use it to test how your applications handle corrupted files, validate error handling, and ensure data resilience. All processing happens client-side—files are never uploaded.

Affects 10% of the file (higher = more corrupted)
Byte Randomization: Replaces random bytes with garbage data (including critical header bytes)—guaranteed to corrupt most files
Header Damage: Corrupts the first 200 bytes—breaks file format recognition and makes files unreadable
Delete Random Bytes: Removes bytes at random positions—causes structure misalignment
Insert Junk Data: Inserts random bytes at random positions—breaks file parsing
Truncate: Cuts off the end of the file—simulates incomplete downloads or transfers
Zero Out: Replaces bytes with zeros—simulates certain disk failures
Bit Flip: Randomly flips individual bits—simulates subtle storage/transmission errors
