Steganography Studio
Hide, extract, and analyse hidden data in images while learning how least significant bit steganography works.
This tool is for education, digital forensics training, and legitimate privacy research. Do not use it to conceal illegal activity or obstruct investigations.

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.
