Corrupt an EXE File Online
Corrupt a Windows .exe file online for free. Destroys the MZ stub and PE header so Windows refuses to load the executable.

Corrompi il tuo file EXE
Calibrato per .exe, .msi, .scr, e funziona altrettanto bene con qualsiasi altro formato.
Perché i file EXE sono difficili da corrompere per bene
A Windows executable is validated by the loader before a single instruction runs. The DOS MZ stub points to a PE header, which describes every section, import and entry point. Damage that chain and the program never starts, no crash, no partial execution, just a refusal.
Cosa distrugge questo strumento
- The MZ / DOS stub. The
MZsignature and the offset it carries to the PE header are destroyed. - The PE header. The
PE\0\0signature, COFF header and optional header describing the entry point are overwritten. - The section table. The records mapping
.text,.dataand.rsrcinto memory lose their structure. - Code and resources. Entropy is scattered through the sections, so even a manually rebuilt header points at unusable code.
Cosa vedrai dopo
| Applicazione | Comportamento |
|---|---|
| Windows | "This app can't run on your PC" or "%1 is not a valid Win32 application." |
| Windows Defender | Flags the file as malformed rather than executing it. |
| Dependency Walker / PE tools | Report an invalid PE image. |
| Wine on Linux/macOS | Refuses to load the binary. |
Motivi comuni per farlo
- Testing that an installer verifies its payload before running it.
- Verifying a software updater detects a corrupt download and retries.
- Checking that code-signing validation actually fires on a damaged binary.
- Producing malformed PE files for a static analysis test suite.
Come corrompere un file EXE
- Trascina il tuo file .exe nel riquadro qui sopra, oppure fai clic per sfogliare.
- Lascia il livello su Standard, a meno che tu non voglia un danno parziale (Light) o debba sconfiggere un software di recupero (Heavy).
- Premi Corrompi file. L'elaborazione avviene sul tuo dispositivo, quindi termina quasi subito.
- Scarica il risultato. Per impostazione predefinita mantiene il nome file e la lunghezza in byte originali.
Domande frequenti su EXE
Is a corrupted EXE dangerous to run?
It cannot run at all: Windows rejects it at load time, before any code executes. That said, only corrupt executables you own or are authorised to test.
Will antivirus flag the result?
Some engines flag malformed PE files as suspicious purely because the structure is invalid. That is expected behaviour, not a detection of anything harmful.
Does it work on MSI installers?
MSI is an OLE compound document rather than a PE binary, and is handled through that profile. It breaks just as reliably.
Can the executable be repaired?
No. The header chain and section table are destroyed, and the code itself is scattered.
