CTF & forensics
Steganography detector
Scan an image for hidden data: bytes appended after the image ends, embedded files (ZIP, PDF, another image), metadata, plus a least-significant-bit view that can reveal hidden layers. All on your device.

Does a finding prove something is hidden?
No — these are hints, not proof. Appended bytes and embedded signatures are strong signals (and a classic CTF trick), but padding and container quirks can also trigger them. The LSB view is a lead to investigate, not a verdict.
What about the least-significant-bit view?
LSB steganography hides data in the lowest bit of each pixel. We amplify that bit to full black/white — if a hidden image or text was embedded there, it often shows up as a clear pattern instead of random noise.
