Have you ever tried opening an MP4 file on your Windows 11 computer, only to find it won’t play? Don’t worry — you’re not alone. MP4 is one of the most common video formats, but sometimes your PC needs the right app or settings to play it smoothly.
In this beginner-friendly guide, we’ll show you how to play MP4 files on Windows 11 using different methods, from built-in apps to advanced players.
What Is an MP4 File?
MP4 (MPEG-4 Part 14) is a popular digital video format that can store video, audio, subtitles, and even images. It’s widely used because it offers good quality at small file sizes — perfect for streaming, downloading, or sharing.
Does Windows 11 Support MP4 Natively?
Yes, Windows 11 supports MP4 playback out of the box. However, if the MP4 file uses a rare codec, you may need to install additional software or codecs.
Method 1 – Play MP4 Files Using the Built-in Media Player
Windows 11 comes with a new Media Player app (replacing the old Groove Music and Windows Media Player).
Steps:
Right-click your MP4 file.
Select Open with > Media Player.
Click play — that’s it!
This works for most standard MP4 files.
Method 2 – Use the Movies & TV App (Legacy Option)
Some older Windows 11 builds still include this app.
Steps:
Right-click the MP4 file.
Choose Open with > Movies & TV.
Play your video.
Method 3 – Play MP4 Files with Windows Media Player (Classic)
If you prefer the classic version:
Steps:
Search Windows Media Player from the Start menu.
Drag and drop your MP4 file into the player.
Press play.
Method 4 – Install VLC Media Player (Best for All Formats)
VLC is a free, open-source player that plays almost anything.
Steps:
Download VLC from videolan.org.
Install and open it.
Click Media > Open File and select your MP4.
No extra codecs needed.
Method 5 – Use Other Third-Party Media Players
If VLC isn’t your style, try:
KMPlayer – Lightweight and customizable.
PotPlayer – Advanced settings for enthusiasts.
GOM Player – Good for subtitle management.
How to Fix MP4 Files That Won’t Play
Sometimes the file is fine — it’s your system that needs tweaking.
1. Install Missing Codecs
Download the K-Lite Codec Pack to add missing codecs.
2. Update Your Media Player
Outdated apps may not support newer formats.
3. Convert the MP4 File
Use a free converter like HandBrake to change it to a more compatible format (e.g., .avi, .mkv).
4. Check for File Corruption
Try playing the MP4 on another device. If it fails everywhere, the file may be damaged.
Can You Play MP4 Files in the Browser?
Yes! Just drag the MP4 into your web browser (Edge, Chrome, Firefox) — most modern browsers support MP4 playback.
