The K-Lite Codec Pack is a collection of audio and video codecs for Microsoft Windows DirectShow that enables an operating system and its software to play various audio and video formats generally not supported by the operating system itself. The K-Lite Codec Pack also includes several related tools, including Media Player Classic Home Cinema (MPC-HC), Media Info Lite, and Codec Tweak Tool.[2]


K-Lite adds Video for Windows (VFW) codecs and DirectShow filters to the system, so that DirectShow/VFW based players like MPC, Winamp, and Windows Media Player will use them automatically.


There are four editions of the K-Lite Codec Pack, all free of charge.[2]

  1. Basic: The Basic edition is the smallest version and enables a Microsoft Windows computer to play the contents of AVI, Matroska (MKV), MP4, Ogg, Flash Video (FLV) and WebM files, etc. It only consists of LAV Filters (for video demultiplexing and audio and video decoding), DirectVobSub (for subtitle decoding), Codec Tweak Tool, Icaros ThumbnailProvider and Icaros PropertyHandler.[3] Basic is the only edition that includes neither MPC-HC nor MediaInfo Lite.[4]
  2. Standard: The Standard edition includes all features of the Basic edition plus MPC Video Renderer, MediaInfo Lite and MPC-HC.[5] This package is recommended for normal users.[2]
  3. Full: The Full edition includes all features of the Standard edition plus madVR, DC-Bass Source Mod and Plugin for 3D video decoding (H.264 MVC)[6]
  4. Mega: The Mega edition includes all features of the Full edition plus a few ACM/VFW codecs (e.g. x264VFW and Lagarith), ffdshow, AC3Filter, GraphStudioNext, VobSubStrip and FourCC Changer.[7]

After version 10.0.0, 64-bit codecs are integrated into the regular editions. Prior to this version there was a 64-bit edition designed specifically for 64-bit OSes.

After version 11.3.0, the 32-bit and 64-bit versions of LAV Filters share their settings, and an option to install only 64-bit codecs was added (visible only in Expert install mode).

After version 13.7.5, a user can remove installed components by deselecting them while running an updater. This also makes it possible to switch to a smaller variant of the codec pack without uninstalling first.

In the past some editions of the K-Lite Codec Pack included BS.Player, until it was supplemented with an adware package.[8]


K-Lite Codec Packs are compatible with Windows Server 2003 and later.[9]

The last version that is compatible with Windows XP SP3 is version 13.8.5.[10]

Starting with K-Lite version 10.0.0, 64-bit codecs were integrated into the regular K-Lite Codec Pack. Previously, a separate 64-bit edition of the pack was available for x64 editions of Windows.[11]
