MOV (QuickTime Movie) uses lossless or lossy encoding and is best for Apple ecosystem — Final Cut Pro, iMovie, and macOS video editing workflows. MKV (Matroska Video) uses lossless container encoding and excels at advanced video archiving with multiple subtitle tracks, chapters, and audio streams in one file. Converting between them lets you take advantage of each format's strengths — for example, using a compressed format for sharing and a lossless format for editing. All conversion happens locally in your browser with no file size limits.
