Convert MKV to MP4 — Play Your Videos Everywhere
MKV is a powerful container format loved by media enthusiasts, but most phones, smart TVs, and social platforms simply will not play it. Converting MKV to MP4 gives you universal compatibility without sacrificing quality. When your MKV already uses H.264, our converter can remux the file nearly quickly — no re-encoding needed.
After conversion, you can compress the MP4 to save storage space, or add AI subtitles to make the content more accessible. Need to go in the other direction? Our video converter handles any format combination.
How to Convert MKV to MP4
Upload Your MKV File
Drag and drop your MKV file — we handle all common codecs including H.264, H.265, VP9, and more. Up to 500 MB without an account, 1 GB with a free account, 5 GB on Pro (20 GB on Studio). The tool automatically detects whether remuxing or re-encoding is needed.
Smart Conversion
If the MKV video stream is already H.264, we remux directly to MP4 — nearly instant with no loss when the codec is compatible. For other codecs, we re-encode with optimized H.264 settings that preserve visual fidelity at a smaller file size.
Download Your MP4
Your universal MP4 is ready quickly. Stream it on any device, upload to YouTube, or continue editing. Want subtitles? Generate them with AI or convert an existing subtitle file to match.
