MKV to MP4 Converter

Repackage an MKV file as an MP4 so it plays on iPhone, Apple TV, smart TVs, and every social platform that refuses to touch Matroska. The default track is used; subtitle tracks are dropped unless they are already burned in.

Converting MKV to MP4 in practice

MKV to MP4 is about playing your video everywhere. MKV is a flexible container popular for high-quality rips, but phones, browsers, smart TVs and editing apps frequently refuse it. Repackaging to MP4 makes the same video “just work” on the devices people actually use, often without re-encoding when the codecs are already compatible.

Convert here when a file plays fine in your desktop media player but will not open on a phone, upload to a platform, or import into an editor. You keep the picture and sound; you are simply switching to the container the rest of the world expects.

When to convert MKV to MP4

  • Make MKV anime or movies playable on iPhone and iPad
  • Upload Blu-ray rips to Plex or Jellyfin as MP4
  • Stream MKV files through Chromecast (which prefers MP4)

About the MKV and MP4 formats

MKV

MKV (Matroska) is the power user’s container. It can hold unlimited video, audio, and subtitle tracks of any codec, which is why anime, Blu-ray rips, and multi-language films ship as MKV. The downside: phones, smart TVs, and most social platforms refuse to play MKV directly — you almost always need to remux to MP4.

MP4

MP4 (MPEG-4 Part 14) is the most widely supported video container on the planet. It packs H.264 or H.265 video with AAC audio into a single file that plays natively on iPhone, Android, Windows, macOS, web browsers, smart TVs, and every modern editor. Use MP4 when you need a finished, shareable video that will just work, anywhere, without re-encoding.

How it works

How to convert MKV to MP4

  1. Upload or paste a MKV link

    Drop a MKV file from your device, or paste a public URL pointing to the MKV you want to convert.

  2. Confirm MP4 as the output format

    The output is pre-set to MP4.

  3. Start the conversion

    Click Convert. Our cloud workers fetch the MKV, scan it for malware (video and audio over 1 GB are not scanned), and run the MKV → MP4 pipeline.

  4. Download your MP4 file

    A download link appears as soon as the MP4 is ready; it works for anyone who has it until the file is deleted. The file is deleted from our storage two hours after it was made (longer for very large files or with a pass), normally within the next 15 minutes.

MKV to MP4 — Frequently asked questions

Soft subtitle tracks embedded in the MKV do not survive the conversion. To keep subtitles, burn them into the video first using a tool like HandBrake or mkvtoolnix, then convert.
