Portable Executable — the Windows .exe/.dll binary format.
| 0x00000000 | 4D5A | MZ | DOS 'MZ' stub |
A 4-byte offset at 0x3C points to the 'PE\0\0' (50 45 00 00) signature.
PE is the Windows format for executables, DLLs and drivers, still carrying a DOS 'MZ' stub for backward compatibility. Files start with 'MZ'; a pointer at offset 0x3C leads to the 'PE\0\0' signature.
Have a file that might be PE (Windows executable)? Identify it with the File Type Identifier — it reads the magic number locally, nothing is uploaded. Or browse all formats.
