PNG is a lossless image compression format (as opposed to JPEG, for example). Have you actually experienced pixels being changed during a roundtrip compression/decompression?

i done it with these steps :
get R,G,B from every pixel and convert it to Binary array then change the LSB to 0 or 1
then convert it from binary to dec
then set-pixel method

after that i save it with the code above
i don know where the problem is :S
