HEVC to MPEG Converter

HEVC to MPEG Converter

HEVC (H.265) is a 2013 high-efficiency codec; MPEG here means the 1990s MPEG-1/MPEG-2 family. This is a deliberate modern-to-legacy downconvert — you re-encode a compact, modern stream into a far older codec that legacy DVD authoring tools, VideoCD pipelines, and old hardware players can actually read. On this page the output defaults to MPEG-2 video with MP2 audio in an MPEG program stream; MPEG-1 video is also selectable under Advanced settings.

Read This First — It's the Wrong Direction for Most People

HEVC was finalized in November 2013 and is roughly twice as efficient as MPEG-2 and far more efficient than MPEG-1. Re-encoding HEVC down to MPEG is lossy-to-lossy into a much older codec: at the same visual quality the file usually gets noticeably larger (commonly around 2x for MPEG-2, more for MPEG-1), and you gain no fidelity — you can't recover detail that HEVC already discarded. Only do this when a specific legacy target demands MPEG: an old DVD-authoring tool, a VideoCD/SVCD, or a hardware player/broadcast chain that only accepts MPEG-1/MPEG-2.

If your real goal is broad, modern playback, convert to H.264 instead via HEVC to MP4 — H.264 plays on essentially every device made since 2010 and is far more efficient than any MPEG-1/MPEG-2 output.

MPEG-1 vs MPEG-2 — Which "MPEG" Do You Need?

"MPEG" is the standards group, not a single codec. The .mpeg / .mpg extension can carry either MPEG-1 or MPEG-2 video. They are different, non-interchangeable bitstreams — pick the one your target requires.

Default output is MPEG-2 (the DVD/broadcast codec). Switch the Video Codec to MPEG-1 under Advanced settings only if you're authoring a VideoCD or feeding hardware that specifically needs the older bitstream.

HEVC vs MPEG — At a Glance

How to Convert HEVC to MPEG

1. Upload Your HEVC File: Drag and drop or click "+ Add Files" to select one or more HEVC (.hevc, .h265) videos. Batch conversion is supported — drop a whole folder at once.
2. Pick a File Compression Mode: Default is Quality Preset set to "Very High (Recommended)". For a fixed disc target, switch to Specific file size; use Constant Bitrate for a predictable stream (e.g. 6-8 Mbps to stay under the DVD-Video 9.8 Mbps ceiling), or Variable Bitrate for better quality at the same average rate.
3. Set Resolution, Trim, or Pick MPEG-1 (Optional): Choose a Preset Resolution (480p / 720×480 for NTSC, 576p / 720×576 for PAL), scale by Resolution Percentage, or set Width × Height. Use Trim → Time Range for a single segment. To output MPEG-1 instead of MPEG-2, change the Video Codec under Advanced; audio defaults to MP2 and can switch to AC-3.
4. Convert and Download: Click Convert. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after conversion — no sign-up, no watermark, never shared.

Frequently Asked Questions

Is the .mpeg output MPEG-1 or MPEG-2?

By default it is MPEG-2 video (ISO/IEC 13818-2) with MP2 audio, wrapped in an MPEG program stream — the codec DVD authoring tools and most legacy hardware expect. If you specifically need the older MPEG-1 bitstream (for VideoCD or certain very old players), switch the Video Codec to MPEG-1 under Advanced settings. The two are not interchangeable: a player that only decodes MPEG-1 will not play an MPEG-2 stream, and vice versa.

Will the MPEG file be larger than my HEVC source?

Almost always, yes. HEVC is roughly twice as efficient as MPEG-2 (and far more efficient than MPEG-1), so at the same visual quality the MPEG output is typically about 2x the size for MPEG-2 — more for MPEG-1. In our testing a 3 GB iPhone HEVC clip re-encoded to MPEG-2 at matching quality landed in the 5-7 GB range. There is no fidelity gain from this conversion; if you need a smaller file, target a specific size or use HEVC to MP4 with H.264 instead.

Why would anyone downconvert modern HEVC to a 1990s MPEG codec?

Only when a legacy target demands it. DVD-Video is locked to MPEG-2; VideoCD requires MPEG-1; and many old set-top boxes, in-car players, projectors with USB playback, and SD broadcast chains (ATSC 1.0, DVB-T) decode only MPEG-1/MPEG-2 in hardware. HEVC bytes simply fail format validation on those systems. For any goal other than reaching that legacy hardware, this is the wrong direction.

Can MPEG-1 or MPEG-2 carry the HDR or Dolby Vision metadata from my HEVC file?

No. Both MPEG-1 and MPEG-2 predate HDR by two decades and have no HDR support, so HDR10 or Dolby Vision metadata is discarded during the transcode and the output is standard dynamic range. DVD-Video itself is SDR-only, so this is unavoidable for legacy targets. If preserving HDR matters, keep the modern codec — convert to H.264 or H.265 in an MP4 container instead.

Does this output play directly on a DVD player without authoring software?

Not by itself. A DVD player expects a VIDEO_TS folder with .VOB files, IFO/BUP index files, and a UDF filesystem. The MPEG-2 program stream from this converter is the codec-compliant video payload that DVD authoring software (DVDStyler, DVD Flick, ImgBurn, Toast) wraps into that structure. Many DVD players from 2010 onward will, however, read a plain .mpg directly off a USB stick.

My iPhone clip is a .mov — is it really HEVC, and can I still convert it?

Probably HEVC inside. iPhones since the iPhone 7 record HEVC by default when "High Efficiency" is set in Settings → Camera → Formats, even though the file extension is usually .mov. If the converter accepts the file as HEVC you're set; if not, convert the container first with MOV to MP4, then bring the result here for the MPEG step.

How long do you keep my uploaded files?

Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after conversion. Nothing is shared, indexed, made public, or used for training, and no account or email is required. The practical limit on big HEVC files is upload size and your connection speed, not a fixed file cap like the 1 GB ceiling some online converters impose.
