🎬 What is K-Lite Codec Pack?
The K-Lite Codec Pack is a collection of audio and video codecs for Windows. It allows your computer to play almost any media file format without errors.
Normally, Windows media players cannot play all formats like:
MKV
FLV
AVI (some versions)
HEVC / H.265 videos
Older or rare audio formats
K-Lite fixes this problem by adding missing “decoding tools” to your system.
