Reception
In 2012, Lifehacker listed KMPlayer as "one of the best multimedia players in the world".

Seth Rosenblatt of CNET's Download.com also rated KMPlayer 3.0 a score of 5 out of 5, stating that "it is one of the most powerful and excellent freeware video players we've seen. If you want to stream videos then I highly recommend KMPlayer", but it had mentioned a lack of online help or documentation as being a shortcoming.

Tina Sieber, writing for MakeUseOf (MUO), comments that "It natively supports a wide range of audio and video formats … it has many advanced features, it is extremely customizable, and it can be available in multiple languages", "If you want to look for a more versatile multimedia player for Windows, KMPlayer may be just the one for you.", "The KMPlayer interface is almost simple enough for most of the average people to be able to use it as a basic and affordable media player."
