Need help?How to Convert MKV to MPEG-2 Online
- Upload Your MKV File: Drag and drop or click "Add Files" to select.mkv files — Plex / Jellyfin library rips, MakeMKV blu-ray and DVD rips, recorded streams, or anime / TV-show downloads. Batch upload is supported, drop in a whole season folder at once.
- Pick Video Codec and Quality: Default output codec is MPEG-2 (the DVD-Video standard). The MKV's H.264, H.265, AV1, VP9, or other internal codec re-encodes to MPEG-2 — keep it for DVD authoring or pick MPEG-1 for VCD-era hardware, MPEG-4 / DivX / Xvid for legacy STBs, or H.264 / H.265 if your container target accepts them. Choose a Quality Preset (Highest → Lowest), target a File Size Percentage (default 80%), set an exact MB target, dial a Constant Bitrate (default 4 Mbps) or Variable Bitrate (2-8 Mbps min/max), or fine-tune CRF (18 = visually lossless, 23 = default, 28 = smaller). Audio defaults to MP2 — keep it for DVD-authoring tools, pick AC-3 to preserve Dolby Digital 5.1 surround from the MKV's audio track, or pick AAC / MP3 for lower bitrate.
- Resize, Trim, or Keep Original: Pick a Preset Resolution (4320p / 2160p / 1440p / 1080p / 768p / 720p / 648p / 576p / 480p / 360p / 240p / 144p — these set height only, with the width following your source's aspect ratio), enter a custom Width × Height, or scale by percentage. DVD authoring needs 720 × 480 NTSC or 720 × 576 PAL, and only Width × Height can pin those exact frames. Use Trim with start time + duration in HH:MM:SS.sss format to drop intros, anime OPs, sponsor segments, or to split a multi-episode MKV into individual MPEG-2 files.
- Convert and Download: Click Convert. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — no sign-up, no watermark, never shared.
Why Convert MKV to MPEG-2?
MKV (Matroska, 2002) is the flexible open-source container the modern ripping and Plex / Jellyfin world standardized on — it carries any codec (H.264, H.265, AV1, VP9), unlimited audio tracks, soft subtitles, chapters, and metadata. MPEG-2 (ISO/IEC 13818-2, 1996) is the older codec baked into the DVD-Video spec and most broadcast workflows. Converting MKV to MPEG-2 is what you do when you need to take a modern rip back to a hardware-decodable format for DVD authoring, broadcast playout, or a legacy player that refuses anything newer.
- Burning a playable DVD from an MKV rip — DVDStyler, ConvertXtoDVD, TMPGEnc Authoring Works, and Adobe Encore all need MPEG-2 elementary or program streams with MP2 / AC-3 audio. Feeding raw MKV (especially with H.265 or AV1 inside) usually fails or forces an internal re-encode that you can't quality-tune. Pre-encoding to MPEG-2 at 4-8 Mbps gives you control over the bitrate budget that fits the disc.
- Broadcast and playout feeds — ATSC over-the-air, DVB-T / DVB-S, and many cable / satellite contribution feeds still spec MPEG-2 at 4-15 Mbps. A station's playout server expects an.mpeg2 /.m2v file, not an MKV with H.265 inside.
- Legacy hardware playback — Set-top boxes, in-flight entertainment systems, hospital TV systems, older car DVD players, and projectors from the 2000s decode MPEG-2 in hardware but stall or refuse on H.264, H.265, AV1, or anything else MKV typically holds.
- Editing in MPEG-only NLEs — Older Premiere builds, Vegas Pro, and TMPGEnc Authoring Works ingest MPEG-2 cleanly but choke on MKV. Converting first removes the Matroska container layer that those tools' demuxers can't parse.
- DVB / IPTV recording archives — Stations and PVR users sometimes need recordings re-saved as MPEG-2 transport streams to match the original broadcast spec for compliance or replay archives.
- Ripping anime or TV-series MKVs back to disc — Fans re-burning a season pulled from streaming or torrent rips need MPEG-2 + MP2 / AC-3 to author a playable DVD; the source MKV almost always has H.264 or H.265 video and AAC / FLAC audio that DVD-Video doesn't carry.

Codec and Audio Choice Quick Guide
| Output video codec | File size vs MKV source | Best for |
|---|---|---|
| MPEG-2 (default) | 2-3× the MKV size at matching quality | DVD authoring, broadcast, legacy hardware |
| MPEG-1 | Larger than MPEG-2 at matching quality | VCD-era players, embedded systems |
| MPEG-4 / DivX / Xvid | ~1.5× the MKV size | Older DivX / Xvid hardware boxes |
| H.264 | Same or smaller than MKV | If your target accepts H.264 in this container |
| H.265 / HEVC | ~50% of source | Modern decoders, smaller archives |
| Output audio codec | Notes |
|---|---|
| MP2 (default) | Standard MPEG audio — accepted by every DVD-authoring tool and broadcast deck |
| AC-3 (Dolby Digital) | Preserves 5.1 surround if the MKV has it; widely supported by authoring tools |
| AAC | Higher efficiency but not part of the DVD-Video spec — pick only if your downstream player accepts it |
| MP3 | Common for general playback; not DVD-Video-spec |
Frequently Asked Questions
Will my MKV's H.265 / HEVC video re-encode to MPEG-2?
Yes. MPEG-2 is a different codec generation from H.265, so a re-encode is unavoidable — there's no remux path. The output will be 3-5× larger than the H.265 source at matching visual quality (a 1 GB H.265 MKV typically becomes a 3-4 GB MPEG-2 file at default settings). Pick the "Highest" quality preset or CRF 18 for an archival-quality re-encode, or accept the default ~4 Mbps CBR for a DVD-budget bitrate.
What happens to my MKV's multiple audio tracks and subtitles?
MPEG-2 elementary and program streams typically carry one video and one audio track — they don't have first-class slots for multiple audio languages or soft subtitles the way MKV does. The default conversion writes the first audio track and drops the others; soft subtitles (SRT, SSA, PGS) are dropped. If multi-track preservation matters, target a different container — see MKV to MP4 for an MP4 that keeps multiple audio tracks, or MKV to MOV for QuickTime workflows.
Should I pick MPEG-2 video or MPEG-4 / Xvid?
MPEG-2 if you're authoring a DVD-Video disc, feeding broadcast playout, or targeting any device that explicitly requires MPEG-2 — it's the only codec the DVD-Video spec accepts for video. MPEG-4 / Xvid / DivX produces ~30-50% smaller files at comparable quality and is the right pick for older DivX-certified DVD players, embedded car STBs, or generic playback on legacy hardware that lists DivX support. If unsure and the goal is DVD authoring, stay on the MPEG-2 default.
What resolution should I target for DVD authoring?
NTSC DVDs are 720×480 (USA, Canada, Japan), PAL DVDs are 720×576 (Europe, Australia, most of Asia). Picking either as a custom width × height matches the DVD-Video spec exactly. Resizing a 1080p or 4K MKV down to 720×480 is required for DVD playback — leave at 1080p / 2160p only if you're not authoring a disc and your downstream tool accepts higher MPEG-2 resolutions. Upscaling beyond the MKV's native dimensions doesn't recover detail and just inflates the bitrate.
Will Dolby Digital 5.1 surround survive the conversion?
Yes — pick AC-3 as the audio codec. AC-3 (Dolby Digital) is one of the audio formats the DVD-Video spec officially carries, and choosing it passes the MKV's AC-3 5.1 track through bit-for-bit. If the MKV has DTS, FLAC, TrueHD, or Atmos audio, those re-encode to AC-3 (loses Atmos object metadata but preserves channel count). MP2 (the default) is stereo-only.
What's the practical file size limit?
Free uploads are limited to 400 MB per file and 5 jobs at a time; Basic raises the video cap to 1 GB and Pro to 4 GB. Multi-GB MKV rips (10-30 GB Blu-ray or DVD rips) therefore need trimming or splitting first. Unlike Convertio's 100 MB free cap, the free tier covers most single episodes.
How do I split a multi-episode MKV into one MPEG-2 file per episode?
Use the Trim option once per episode. Set a start time and duration in HH:MM:SS.sss format (e.g., start 00:00:00, duration 00:24:30 for a 24-and-a-half-minute first episode, then 00:24:30 / 00:24:30 for the second), and run the conversion once per range. Each output is a clean MPEG-2 file that DVD-authoring tools accept as its own title or chapter. Merge later if needed in your DVD-authoring tool.
Can I go the other direction — MPEG-2 back to MKV?
Yes — see MPEG-2 to MKV for the reverse, useful if you're pulling DVD rips into a Plex / Jellyfin library. For modern targets, also see MKV to MP4 (universal playback) and MPEG-2 to MP4 (DVD-rip modernization).
