In this 21st century, the inability to securely transmit information over a digital medium has been a major problem because the information stands a chance of being intercepted by hackers before it reaches its destination. Therefore Stenography was introduced to prevent sensitive information from been accessed by unauthorized persons. Stenography is a method of encrypting data as related to cryptography but hides a message in plain sight thereby making it a more secure method of sending across secret information. In this study variants of the least significant bit (LSB) method was implemented and performance comparative analysis was carried out across three image format. The result obtained from that the mean square error (MSE) and peak signal to noise ratio PSNR analysis, indicate that PNG and Bitmap image performed better than GIF images
