About this video
🎨 Ever wondered how to hide secret text inside an image — completely invisible to the human eye?
In this video, I’ll show you how to use Python and the alpha channel of a PNG image to store hidden messages that can only be revealed by those who know where to look.
This technique is based on steganography — the art of hiding information inside ordinary files.
Using just a few lines of code, we’ll:
- Upload an image
- Embed a secret message using alpha == 254
- Save the image so it looks normal but secretly contains your text
- Then extract and reveal the hidden message again!
Perfect for learning about image processing, data hiding, and creative coding in Python.
💻 Code file: https://github.com/pythonbymask-coder/youtube/blob/main/Invisible-Text-Hidden-Inside-Every-PNG/hidden_message.ipynb
🧠 Concepts: Alpha Channel • Transparency • Steganography • Python Imaging Library (PIL)
