How to convert MXF to Y4M
To convert MXF to Y4M, upload your MXF file, choose Y4M as the output format and press Convert. The finished Y4M file is ready to save to your phone or computer in seconds, free, with no watermark and no sign-up. Your file is deleted from our server about 30 minutes after the conversion.
This free online converter turns MXF videos into Y4M files in your browser, with no software to install and no watermark. When the video and audio inside your MXF file can be placed in Y4M as they are, the streams are copied without re-encoding, which is faster and keeps the original quality. Otherwise the video is re-encoded as raw uncompressed YUV4MPEG2 video (no audio, up to 720p).

What to expect from this conversion

- Y4M stores raw frames without compression and without audio. To keep the file manageable, output is limited to 720p, and it is still very large.
- MXF files are broadcast-sized, so uploads can take a while on slower connections.
- The first audio track is kept. Subtitle tracks, extra audio tracks and chapters are not included in the converted file.
