Supports: M2V
An .m2v file is a bare MPEG-2 video elementary stream — compressed picture data with no container and no audio track. Converting it to .mpeg wraps that same video into an MPEG-2 program stream, the self-contained format that ordinary media players, DVD tools, and editors expect. Because the source M2V carries no sound, the resulting MPEG is silent unless you add audio separately — the gain here is playability, not new content.

.m2v file onto the page or click "+ Add Files". You can queue several files and convert them with the same settings.It is mostly a re-wrap. The M2V stream already holds MPEG-2 video, and a .mpeg program stream uses MPEG-2 video as well, so at the default Quality Preset the picture is bundled into a playable container with little to no transcoding. If you change the resolution, set a target file size, or pick a different bitrate, the video is re-encoded and some quality is lost.
Because the source M2V had no sound to begin with. An M2V elementary stream is video-only — it cannot store an audio track. The MPEG program stream supports audio, but this conversion has no audio to carry over, so the output is silent. To get sound, you need to mux a separate audio file (such as the AC3 or LPCM track that originally accompanied the M2V in a DVD-authoring project).
An elementary stream is the raw output of a single encoder — just compressed video, with no timing wrapper and no audio. A program stream multiplexes one or more elementary streams (video plus audio and data) into one self-contained file meant for storage and playback in error-free environments like a local disc. M2V is the former; .mpeg here is the latter.
At the "Very High (Recommended)" preset, yes — the existing MPEG-2 video is carried into the program stream essentially unchanged, so there is no generation loss. Quality only drops if you actively re-scale the resolution or target a smaller file size, both of which force a re-encode.
They are closely related. .mpeg, .mpg, and .mpeg2 are common extensions for MPEG program-stream files, and players generally treat them interchangeably. The internal stream is the same MPEG-2 program stream regardless of which of these extensions you use; the differences are conventional rather than technical.
Yes. If your goal is wide device and web compatibility rather than DVD/legacy workflows, convert to MP4 with M2V to MP4, which re-encodes to H.264. For DVD disc structures specifically, M2V to VOB targets the DVD Video Object format. MPEG (program stream) is the right pick when you want a self-contained, broadly playable MPEG-2 file with minimal re-encoding.
Yes. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours. There is no sign-up, no watermark, and your files are never shared or made public. In our testing, a 30-second 720p MPEG-2 elementary stream re-wrapped to MPEG in a couple of seconds at the default preset, with the output file size staying close to the source.
