Every common person uses internet directly or indirectly in some spheres of his life. They mainly use the internet for information sharing. Also, information sharing has the primary importance in the field of Military Services, Medical Services, Mobile Services, and Investigation Agencies etc. The main hurdle in the path of information sharing is the security of information. The information security can be achieved by Cryptography and Steganography. But now days, Steganography is the most burnt area. There are lot of research is going on steganography. In this paper, we analyze various image steganography techniques by using peak signal to noise ratio (PSNR) Metric. After analyzing the techniques, we found that 6th, 7th and 8th Bit Method provides highest PSNR values and LSB Method provides lowest PSNR values.
