Converting MKV to MP4 in VLC is one of the simplest and most accessible methods for users who want to transform their video files without downloading any additional software. Still, its broad compatibility isn't as universal as the MP4 (MPEG-4 Part 14) format, which is natively supported by almost all devices, platforms, and media players. For those unfamiliar, MKV (Matroska Video) is a highly flexible open-source container format that supports multiple audio, video, and subtitle tracks. By learning how to convert MKV to MP4 in VLC, you gain a powerful, free tool that can handle this task efficiently, ensuring your videos are playable everywhere you need them to be.
Why Convert MKV to MP4?
Before diving into the process, it’s helpful to understand the practical reasons for making this conversion.
- Universal Compatibility: MP4 is the gold standard for video on the web and mobile devices. While most modern players can handle MKV, older smart TVs, some game consoles, and certain web browsers may struggle with it.
- Smaller File Size: MP4 files are often more compressed without a significant loss in quality, making them easier to share and store.
- Standardized Subtitles: MP4 uses more standardized methods for embedding subtitles (like SRT files), which is often easier for players to display correctly.
- Wider Ecosystem Support: Social media platforms, video editing software, and streaming services are built around MP4. Uploading an MKV file can sometimes cause upload errors or processing delays.

Important Settings and Tips for a Smooth Conversion
While the default settings work well for most users, a few tips can help you get the best results Most people skip this — try not to..
- Preserve the Original Quality: By default, VLC will re-encode the video using the H.264 codec. This is necessary to place it inside an MP4 container, but it can slightly reduce quality. If your source file is already in H.264, VLC will still re-encode it, which is normal. To get the highest quality, ensure your source MKV has a high bitrate.
- Audio Codec: The default profile uses MP3 for audio. If your MKV has Dolby Atmos or DTS audio, VLC will convert it to a standard stereo MP3 track. This is usually fine for most uses, but be aware that you'll lose the high-fidelity surround sound.
- Batch Conversion: You can add multiple MKV files in step 3. VLC will convert them one by one in the order they appear in the list.
- No Video or No Audio: If the "Video - H.264 + MP3 (MP4)" profile isn't suitable, you can create a custom profile. In the profile selection window, choose "Create new profile," name it, and select the appropriate video and audio codecs (like H.264 for video and AAC for audio, which is also a great MP4-compatible choice).

Q: Will the conversion process be slow?
A: It depends on your computer's processing power. Now, the conversion is CPU-intensive because it has to decode the original MKV file and then re-encode it into a new format. Worth adding: a modern computer can handle it fairly quickly, but converting a 2-hour 4K movie might take 30–60 minutes. Closing other applications during the process can help speed it up.
Q: Does VLC preserve subtitles and multiple audio tracks?
On the flip side, a: Yes, but with caveats. VLC will attempt to include subtitle tracks (like SRT or SSA) and all available audio tracks in the MP4. On the flip side, not all subtitle formats are perfectly compatible with MP4 containers. If you encounter issues, you may need to manually select which subtitle track to include in the "Subtitle" tab of the conversion profile settings.
Q: Are there any downsides to using VLC for this conversion?
It doesn’t support advanced features like GPU acceleration for faster encoding, and its batch processing can be slow for large libraries. A: VLC is excellent for occasional conversions, but it has limitations. For frequent, high-volume conversions, dedicated software like HandBrake or FFmpeg might be more efficient.
