Does LSB steganography visible-change the image?

Only least-significant bits flip, so visuals stay nearly identical. Heavy JPEG recompression afterward can destroy hidden data.

How much text can be hidden?

Capacity scales with pixel count—typically a few KB of message is safe. Use large PNG carriers or compress secrets for more data.

Lossless PNG is best. JPG compression scrambles LSB payloads and raises extraction failure rates.
