What executable formats can this tool inspect?

It inspects Windows Portable Executable (PE .exe and .dll), Linux Executable and Linkable Format (ELF 32/64-bit), and macOS Mach-O (Mach-O 64-bit and Fat binaries).

Is my binary executable uploaded to a server?

No. The inspector reads only the initial header bytes of the binary using browser FileReader and DataView. The file never leaves your machine.

Executable Header Inspector (PE, ELF, Mach-O)

Analyze binary executable files directly in the browser. Inspect Windows PE (.exe/.dll), Linux ELF, and macOS Mach-O header tables, machine architectures, entry points, and compiler security mitigations offline.

Frequently Asked Questions

What security mitigations are detected?

The tool audits for ASLR (Address Space Layout Randomization), DEP / NX (Data Execution Prevention), and Control Flow Guard (CFG) in Windows PE headers, and ELF flags (like GNU_STACK executable flags).

Can this tool run malware on my machine?

No. The browser strictly parses header bytes as an ArrayBuffer and displays textual properties. The binary is never executed, loaded as native code, or launched.
