How to convert Y4M to MPEG
To convert Y4M to MPEG, upload your Y4M file, choose MPEG as the output format and press Convert. The finished MPEG 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 Y4M videos into MPEG files in your browser, with no software to install and no watermark. When the video and audio inside your Y4M file can be placed in MPEG 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 MPEG-2 video with MP2 audio.
