K-Lite Codec Pack is a collection of DirectShow filters, VFW/ACM codecs, and tools. Codecs and DirectShow filters are needed for encoding and decoding audio and video formats. The K-Lite Codec Pack is designed as a user-friendly solution for playing all your audio and movie files. With the K-Lite Codec Pack you should be able to play all the popular audio and video formats and even several less common formats.

The K-Lite Codec Pack has a couple of major advantages compared to other codec packs:

  • It is updated frequently. So it is always up-to-date with the newest and/or best components.
  • All components have been carefully selected for specific purposes. It is not just a random bunch of stuff thrown together.
  • It is very user-friendly and easy to use.
  • The installation is fully customizable, meaning that you are able to install just those components that you really want.
  • The customization abilities even go beyond the component level. Some components are able to handle multiple formats.
  • You can specify exactly which components should handle which formats. The pack can thus be fully tweaked to your own specific needs and preferences.
  • Uninstallation removes everything that was installed by the pack. Including all registry keys.
  • It is extremely easy to make a fully customized unattended installation with the integrated wizard.
  • It does not contain any bad, buggy or unstable codecs.
  • It tries to avoid potential conflicts with other codecs installed on your computer. The installation is able to detect and remove over 100 different codec and filter packs.
  • The pack is able to detect broken codecs and filters on your system, and helps you to remove them.
  • It is a very complete package, containing everything you need to play your movies.
  • This pack has a huge user base. This means that problems are found and resolved quickly.
  • There are different variants of the pack. From very small to large.
  • The pack is suitable for both novice and expert users.
  • The basic variant contains everything you need to play all the common video file formats. Such as AVI, MKV, MP4, OGM, and FLV. This pack is for those who like a small no-nonsense pack.

Note: the Basic version does NOT include a player.
You need to use it together with an already installed DirectShow player such as Windows Media Player. For playback issues with WMP please read our F.A.Q. for solutions.

We recommend using K-Lite Standard, which includes MPC-HC, which is a very good player.
