Steganography

Hide secret text inside images (LSB) and extract it back — fully in your browser.

About Steganography

Steganography hides the existence of a message by embedding it into a carrier (like an image). This tool uses a simple, educational approach — the Least Significant Bit (LSB) method on the RGB channels. Export is forced to PNG to avoid lossy compression issues that would corrupt hidden data.

Hide Message in Image

Tip: Prefer PNG input for clarity. Output is always PNG.

Capacity depends on image size. Each pixel stores ~3 bits (one per RGB LSB).

Extract Message from Image

If you used this tool to embed, this will work even if you saved as PNG later.

Note: Do not use JPEG for the final stego image; its lossy compression can corrupt hidden data. This tool exports PNG to protect the embedded bits.
