You can change MP4 to MKV when you need more features in one file. An .mkv file can hold multiple audio tracks, subtitles, chapters, and high bitrates. It’s excellent for storing movies, TV shows, and videos with many languages or captions. If an app requires MKV, or you want better control over tracks, converting MP4 to MKV will be the easiest solution.

It’s simple. Open AhaConvert in your browser. Upload your MP4 video and choose MKV as the output format from the available options. Click convert. Wait for the process to finish, and then download your MKV file.

The answer is simple: Use a player that supports MKV natively. VLC Media Player is the most common choice and works seamlessly on almost all devices. MPC-HC (Windows) and IINA (macOS) are other options. Some smart TVs and streaming boxes also play MKV from USB or apps directly. If your device can’t open an MKV, it may not support the video or audio codec inside it. In that case, using a newer media player or re-encoding the file may help.

No. Transforming MP4 to MKV does not make the picture sharper. The conversion only changes the file container, not the picture itself. So you will get the same video and sound in most cases. However, if you choose to encode the video again during conversion, you may lose some quality. The safe option is to convert to MKV without changing the codec or bitrate.

Yes. AhaConvert lets you convert MP4 to MKV completely free in your browser. There is no signup, no subscription, and no hidden watermarks for simple conversions. Just upload your MP4 file and download the MKV version once it’s ready. That’s it.

Yes, you’re able to upload MP4 files up to 1 GB in size. The limit is enough for long recordings, HD videos, and even short movies. We set the limit at 1 GB because videos larger than that take a very long time to upload through a browser, especially on slower internet connections. Uploading huge files can also make the page load slowly or fail. Therefore, if your MP4 video is bigger than 1GB, consider compressing it or trimming it first. As long as the file is under the size limit, our converter will create a full MKV version of your video.

Right now, AhaConvert converts one video at a time. It keeps the website fast and easy to use in your browser. If you need to convert many videos together, you can upload them one by one. If batch conversion is something you need often, you can tell us. We may add this feature in the future if enough users request it.

Absolutely. All the video files, whether uploaded or downloaded, are kept safe during processing. We use 256-bit SSL encryption, store files in a secure cloud environment, and automatically delete them within 24 hours.
