Need help?How to Convert MPG to MP4 Online
- Upload Your MPG Files: Click "+ Add Files" or drag and drop.mpg,.mpeg,.m1v, or.m2v files from your computer. Batch upload is supported, and ripped VCD/DVD segments combine cleanly inside MP4 containers.
- Pick Quality Preset or Bitrate Mode: Default is Quality Preset → Very High (Recommended), which produces a universally compatible H.264 MP4. Switch to Constant Quality (CRF) for fixed perceptual quality, Constant Bitrate or Variable Bitrate for streaming targets, or Specific file size to cap output (useful for upload limits).
- Resolution and Trim (Optional): Use Video resolution → Preset Resolutions (1080p, 720p, 480p) for a quick downscale, Resolution Percentage to scale by ratio, or Width × Height for custom dimensions. Use Trim → Time Range to keep only the segments you need from a long DVD rip or VHS capture.
- Convert and Download: Click "Convert" and download the MP4. Conversion runs on our servers — no sign-up, no watermark, no email required.
Why Convert MPG to MP4?
MPG (.mpg /.mpeg) is a 1990s container holding MPEG-1 (1993, VCD/MP3) or MPEG-2 (1995, DVD-Video and ATSC broadcast TV) video. MP4 (ISO/IEC 14496-14, 2003) is the modern ISO Base Media File Format container that holds H.264, H.265, AV1, or AAC audio. Re-muxing and re-encoding to MP4 gives you a smaller, web-ready file that plays everywhere.
- Roughly half the size at the same quality — H.264 inside MP4 is significantly more efficient than the MPEG-2 inside a DVD.mpg. A 1 GB DVD-bitrate MPEG-2 stream (~6–8 Mbps) re-encoded to H.264 at visually-equivalent quality typically lands at 350–600 MB.
- Plays in every modern browser and phone — H.264/AAC inside MP4 is supported in Chrome, Firefox, Edge, Safari, iOS, and Android..mpg files often fail to preview in browsers and on mobile without a third-party player.
- Upload-ready for YouTube, Instagram, TikTok, X — all major platforms list MP4 (H.264 + AAC) as the recommended upload container;.mpg uploads frequently get rejected or re-transcoded server-side with extra quality loss.
- Edit-friendly in modern NLEs — DaVinci Resolve, Final Cut Pro, and Premiere all handle MP4/H.264 timelines smoothly; MPEG-2 program streams sometimes require an Apple ProRes or H.264 intermediate before they cut cleanly.
- Future-proof archives of old DVDs and camcorders — the last U.S. MPEG-2 patent (#7,334,248) expired Feb 13, 2018, so the format is royalty-free now, but tooling has shifted to MP4/H.264 for new hardware. Converting locks your library to the format that will keep working.
- Smaller backups for VCD, mini-DVD, and TiVo rips — converting once and discarding the source can free 40–60% of disc space without visible quality loss at default settings.

MPG Source Cheat Sheet
What you usually find on a.mpg file, and the best target settings when converting to MP4.
| Source | Video codec inside MPG | Resolution | Bitrate | Recommended MP4 target |
|---|---|---|---|---|
| Video CD (VCD) rip | MPEG-1 Video | 352 × 240 (NTSC) / 352 × 288 (PAL) | ~1.15 Mbps | H.264, Very High preset, keep original resolution |
| DVD-Video rip (VOB →.mpg) | MPEG-2 (H.262) | 720 × 480 (NTSC) / 720 × 576 (PAL) | 4–9 Mbps | H.264, CRF 18–20, deinterlace if needed |
| ATSC broadcast capture | MPEG-2 | 1920 × 1080i / 1280 × 720p | 15–19 Mbps | H.264 High profile, CRF 20, deinterlace 1080i |
| DVB-T broadcast capture | MPEG-2 | 720 × 576 / 1440 × 1080i | 4–8 Mbps | H.264, CRF 20, deinterlace if interlaced |
| Old PVR / TiVo / camcorder | MPEG-2 | 720 × 480 / 720 × 576 | 4–8 Mbps | H.264, Very High preset, 1080p upscale optional |
Quality Preset Quick Guide
| Setting | What it does | When to use |
|---|---|---|
| Very High (Recommended) | High-quality H.264, sensible default bitrate | Most DVD rips, most archives |
| Constant Quality (CRF 18–23) | Fixes perceptual quality; size varies | Master-quality archives (CRF 18) or web (CRF 22) |
| Constant Bitrate (CBR) | Fixed kbps, predictable size | Streaming targets, broadcast remux |
| Variable Bitrate (VBR) | Quality-aware bitrate over the clip | General web upload, social media |
| Specific file size | Caps output to your target MB | Email caps, Discord limits, learning platforms |
Frequently Asked Questions
What's the difference between.mpg and.mpeg?
They are the same format — only the extension differs..mpg is the three-letter DOS-era extension;.mpeg is the spelled-out variant. Both contain MPEG-1 or MPEG-2 elementary streams in a Program Stream or System Stream wrapper, and both are handled identically by this converter (the acceptedExtensions list includes both).
Will I lose quality converting MPG to MP4?
At the default Quality Preset → Very High, perceptual quality is preserved. H.264 is much more efficient than MPEG-1/MPEG-2, so re-encoding at the same visual quality produces a smaller file. For a near-lossless archive, switch to Constant Quality (CRF) and choose CRF 18; for a "looks identical" web copy, CRF 20–22 is plenty. Avoid Specific file size if you can — bitrate caps below the source produce visible quality loss.
My MPG is from a DVD and looks interlaced. What should I do?
DVD-Video MPEG-2 is usually interlaced (480i / 576i). If you see combing on motion, enable deinterlacing in Advanced Options before converting; the output MP4 will be progressive (480p / 576p) and play correctly on phones and modern TVs. Field rate is preserved (29.97 fps NTSC, 25 fps PAL).
Can I keep the original quality without re-encoding?
If the audio and video codecs are already MP4-compatible (rare for.mpg — MPEG-2 video is not legal in standard MP4 muxers), you can't just remux. The.mpg →.mp4 path almost always requires a video re-encode to H.264 or H.265. The Copy codec option only works when source codecs are already MP4-legal.
Why does my.mpg sometimes play with no audio after conversion?
Older.mpg files often use MPEG-1 Audio Layer II (MP2) or AC-3. The default converts audio to AAC, which fixes this; if you switch the audio codec to Copy and your MP4 player doesn't support MP2/AC-3 in MP4, you may get silence. Leave audio on Auto/AAC for maximum compatibility.
Are.mpg files still under patent?
In the United States, the last MPEG-2 patent (#7,334,248) expired on February 13, 2018, making MPEG-2 royalty-free for U.S. distribution and playback. MPEG-1 expired years earlier. A few jurisdictions (e.g. Malaysia, Philippines) still recognize related patents. MP4's H.264 video codec is still under active patent licensing through MPEG LA.
What's the maximum file size I can upload?
Conversion runs on our servers, so you're bounded by upload size and connection speed on our servers quota. Multi-gigabyte DVD rips work; for very large captures, trim to the segments you need with Trim → Time Range before converting to reduce memory pressure.
Should I pick H.264 or H.265 for the MP4 output?
H.264 (Very High preset) is the safest choice — it plays in every browser and on every phone made since ~2010. H.265 (HEVC) cuts file size another 30–50% but is not playable in Firefox or older Android, and Chrome only added HEVC playback in 2023. Pick H.264 for sharing, H.265 only for personal archives you'll watch on iPhone, modern Apple TV, or recent smart TVs.
Can I convert MP4 back to MPG later?
Yes — see MP4 to MPG for DVD authoring or burning a VCD with legacy compatibility. Related conversions: VOB to MP4 for raw DVD files, MPEG to MP4 for the longer extension, MPG to GIF for clips, and MPG to WebM for browser embedding. To shrink the MP4 further, try Compress MP4; to clip segments, use Video Cutter.
