Expanding CypherAI to include BMP, PNG, MP3, and TXT formats broadens its capabilities significantly. With support for BMP and PNG images, users can hide messages in a wider range of visuals, while MP3 files enable covert communication through audio. TXT file integration provides a straightforward method for concealing text-based messages within documents.

These additions enhance the service's versatility, offering users more options for discreet data transmission across multimedia platforms.
