K-Lite Codec Pack

Windows codec bundle for broad audio and video playback, with MPC-HC included

Free Windows

Bloat

0 · CLEAN*

The codecs and the player it installs are clean. But its installer may add other software — see the box below before you click anything.

What the numbers mean

⚠ Before you install: the installer carries offers

Users reported in 2026 that some K-Lite installs showed an optional third-party offer — a program that shares your internet connection as a proxy (Infatica).

  1. Download from codecguide.com, using the mirrors on its own download page (Basic or Standard is enough for most people).
  2. Choose Normal mode in the installer and read every screen before clicking Next.
  3. If a screen offers any other program — especially anything about sharing bandwidth or "earning" from your connection — click Decline.
  4. Afterwards, check Settings → Apps → Installed apps for anything you did not ask for.

The clean route: If you only want to play files, VLC media player or MPC-HC play almost everything without a codec pack.

About

K-Lite Codec Pack is a free collection of DirectShow decoders, splitters and related tools that lets Windows programs play a wide range of audio and video formats. It is meant for people who use Media Player Classic, Windows Media Player or other DirectShow-based software and want consistent playback of formats Windows does not handle on its own. Four editions are offered: Basic contains only the essential filters, Standard adds the MPC-HC player, Full adds madVR and extra 3D video support, and Mega adds further ACM/VFW codecs and utilities. Core decoding is handled by the bundled LAV Filters, and a Codec Tweak Tool helps diagnose and repair codec problems. Updates arrive frequently, usually to bring in new versions of bundled components such as MPC-HC and MediaInfo.

  • Four editions, from essential filters only to a full toolkit
  • LAV Filters for decoding and splitting most formats
  • MPC-HC player included from the Standard edition up
  • Codec Tweak Tool for diagnosing and fixing codec issues
  • Explorer thumbnails for video files via Icaros

Before you download

  • Windows only.
  • Users have reported some installs bringing an optional third-party offer (Infatica bandwidth-sharing proxy software); read each setup screen and decline extras you do not want.
  • The publisher's FAQ covers a reputation-based Norton warning (WS.Reputation.1) on the installer.
