Need help?How to Convert MPG to MPEG
- Upload your MPG video — Click "+ Add Files" or drag and drop your MPG or MPEG files.
- Choose compression — Under "File Compression," select "Quality Preset" (Highest to Lowest), "Target file size (%)" to reduce by percentage, "Specific file size" in MB/KB, "Constant Bitrate," "Variable Bitrate," "Constant Quality" (CRF), or "Constraint Quality" (CRF + max bitrate).
- Adjust resolution — Under "Video resolution," keep original, pick a preset (1080p, 720p, 480p, etc.), or enter exact width/height.
- Trim if needed — Under "Trim," set a start time and duration to extract a specific clip.
- Convert and download — Click "Convert" and download your MPEG file.
Why Convert MPG to MPEG?
MPG and MPEG are the same format — both use MPEG-1 or MPEG-2 compression and contain identical video/audio data. The only difference is the file extension length (.mpg is the 3-character DOS-era convention, .mpeg is the full name). However, some software and systems specifically require the .mpeg extension, and converting also gives you the opportunity to re-encode with different compression settings — adjusting bitrate, resolution, or trimming the video.
This conversion is useful when software rejects .mpg files but accepts .mpeg, when you need to reduce file size through re-encoding, or when you want to trim a specific clip from a longer recording.
MPG vs MPEG: What's the Difference?
| Aspect | .mpg | .mpeg |
|---|---|---|
| Format | MPEG-1 or MPEG-2 | MPEG-1 or MPEG-2 |
| Codec | Identical | Identical |
| Quality | Identical | Identical |
| Extension origin | DOS 8.3 filename limit | Full name |
| Software compatibility | Most players | Some systems require this |
Frequently Asked Questions
Are MPG and MPEG the same format?
Yes. They are identical formats — same codec, same container, same data. The only difference is the file extension (.mpg vs .mpeg). Some older systems used the 3-character .mpg extension due to DOS filename limitations.
Can I just rename .mpg to .mpeg?
In most cases, yes — simply renaming the file extension works since the format is identical. However, converting through XConvert lets you also re-encode with different compression settings, reduce file size, change resolution, or trim the video.
What compression setting should I use?
If you just need the extension change, use "Quality Preset: Highest" to minimize quality loss. To reduce file size, use "Target file size (%)" or "Constant Quality (CRF)" at 23 for a good balance.
Can I trim the video during conversion?
Yes. Under "Trim," set a start time and duration to extract a specific portion — useful for pulling clips from long MPEG recordings.
What's the difference between MPEG-1 and MPEG-2?
MPEG-1 is the older standard (VCD quality, up to 352×288). MPEG-2 is the DVD/broadcast standard (up to 1920×1080). Both use .mpg/.mpeg extensions. The converter handles both transparently.
