How do I convert MKV to M4V with LetsConvert?

Select your MKV file(s), choose M4V as the output format. The tool remuxes H.264/HEVC video and AAC audio into the M4V container while preserving quality. If your MKV uses incompatible codecs, it re-encodes them. Then click Convert and download the M4V file.

Why should I choose M4V instead of MKV?

M4V is Apple's container format, natively supported by iTunes, Apple TV, iPhone, and iPad. MKV files often contain multiple audio tracks, subtitles, and new codecs, which many media players and Apple devices don't recognize without third-party software. Converting to M4V ensures seamless playback on Apple devices and reduced file size when only video and a primary audio track are kept.

Will the conversion keep subtitles and multiple audio tracks?

LetsConvert remuxes the video and first audio track into M4V without re-encoding if they are H.264/HEVC and AAC/AC3. Additional audio tracks and subtitles are dropped because M4V container support is limited. Video resolution, frame rate, and color profile remain identical. If the source uses a non-compatible codec like VP9, it will be re-encoded to H.264, which may slightly reduce quality and increase processing time.

Is MKV-TO-M4V free to use?

Yes, MKV-TO-M4V on LetsConvert is 100% free with no registration or hidden fees required.
