M4V (MPEG-4 Video)
Apple's variant of MP4, commonly used in iTunes and Apple TV. Nearly identical to MP4 but may include Apple's DRM protection on purchased content.
MKV (Matroska Video)
A flexible container that can hold virtually unlimited video, audio, and subtitle tracks. Popular for high-quality video files but not supported by all devices natively.
Need your file in a different format? Converting from M4V to MKV lets you use your media wherever you need it โ whether it's for compatibility, smaller file size, or a specific app or device that requires MKV files.

We use optimized conversion settings to preserve as much quality as possible. Some quality difference is normal when converting between lossy formats, but it's minimal and usually unnoticeable.
Most files convert in seconds. Larger files may take a bit longer depending on size, but conversion happens right in the cloud so your device stays fast.
You can convert files up to 500 MB. That's enough for most video, audio, and image files you'll need to convert.
