Make files bigger instead of smaller ! WTF ?

I downloaded this app with the intention to compress files, but instead of compressing those files it only made them bigger ( for example 53MB instead of 29MB!!)

Developer Response ,

Thank you for taking the time to let us know you are having this issue. Have you tried reducing the bit rate before conversion? If this doesn't work, please reach out to our support team so that they can investigate this further and provide you with a solution:
