How this MKV to MP4 Converter works
This tool converts Matroska Video (MKV) files to the widely supported MPEG-4 (MP4) format using FFmpeg WebAssembly. The entire process runs locally within your web browser, ensuring your private videos are never uploaded to a server.
The converter prioritizes speed and compatibility by using the libx264 video codec and AAC audio codec. This ensures the output file plays flawlessly on all modern devices, including iPhones, Android phones, smart TVs, and game consoles that often struggle with MKV files.
By leveraging client-side processing, this tool avoids the file size limits and slow upload times typical of server-based converters. You can convert large video files as fast as your computer allows, with immediate access to the downloaded MP4 file upon completion.
