BMP WRAP – TRICK TO SEND FILE HIDDEN AS IMAGE

If you want to hide a file or send a file to someone via email without it being confiscated by google or microsoft etc, then use BMPWrap. Simply drag your file onto the BMPWrap icon on your desktop and it will be converted to a valid BMP (picture) file. Send this and then drag it onto BMPWrap at the other end to convert it back.
