Upload an image and enter your secret text. The message is written into the image's pixel LSBs — each channel byte changes by at most ±1. Result is a PNG.

Decode

02 / reveal message

Upload an encoded PNG to extract the hidden message. Only PNG files produced by this tool can be decoded — re-saving as JPEG destroys the hidden bits.
