FAQ

Common questions

Is steganography the same as encryption?

No. Encryption hides meaning. Steganography hides existence.

Why use PNG instead of JPEG?

PNG preserves pixel values. JPEG compression can change pixels and destroy hidden LSB data.

Can forensic tools always detect steganography?

No. Detection is often probabilistic and depends on the method, image, payload size, and available comparison image.

What is the least significant bit?

It is the rightmost bit in a binary number. Changing it changes the value by only 1.

Does a high entropy score prove steganography?

No. High entropy may indicate compression, encryption, randomness, or hidden data.

Can I compare original and suspected images?

Yes. If both are uploaded, the tool compares pixel differences and highlights likely LSB changes.
