FAQ
Does my file get uploaded?
No. Every analyzer runs locally in your browser — the file never leaves your device.
What can it detect?
File type by magic bytes, Shannon entropy (packing/encryption), strings with flag/URL/key tagging, embedded/carved files, ELF/PE headers and packers, hash identification, and LSB steganography in images and WAV audio.
