Quick answer: To convert MPG to OGV, add the MPG file to the iHateFiles MPG to OGV converter and press Convert. The conversion runs in your browser, so the file is never uploaded, and it is free with no sign-up, watermark or size limit. Re-encodes the picture and sound into a OGV container.
Should you convert MPG to OGV?
Do this when something specifically needs OGV. The picture is re-encoded, so it costs a little quality; if all you need is a file that plays everywhere, MP4 is usually the better target.
The picture is re-encoded
An MPG usually holds MPEG-1 or MPEG-2 video, often interlaced, from a DVD, VCD or camcorder. This writes Theora video with Vorbis sound into the OGV. Both sides are compressed with loss, so this is a second generation: leave the quality at its default or higher, because the encoder is working from MPG artefacts rather than the original.
Watch for interlacing
MPG video from a DVD, camcorder or broadcast is often interlaced, which shows up in the OGV as comb-like tearing on anything that moves. Restore Old Video removes it and can write the OGV in the same pass.
Where the OGV will play
OGV plays on Firefox, Chrome and VLC, but not Safari or most phones.

What usually goes wrong
About the MPG. An MPG from a DVD is interlaced, so it shows comb-like horizontal tearing on movement when played on a computer. Restore Old Video removes it while converting.
About the OGV. At the same file size Theora looks clearly worse than H.264, so re-encoding an old OGV will not recover detail that was never captured.
How to convert MPG to OGV
- Add your MPG file. It is read from your disk and stays there.
- Check the settings. The output format is already set to OGV.
- Press convert and the OGV file is saved back to your device.
Questions
How do I convert MPG to OGV?
Open this page, add your MPG file, and press convert. The file is decoded and re-encoded by your own browser and saved back to your device. Nothing is uploaded.
Is this MPG to OGV converter free?
Yes, completely. There is no account, no sign-in, no watermark and no daily limit, because there is no server doing the work. Your own device does it.
Are my files uploaded anywhere?
No. There is no upload endpoint. The conversion runs inside this browser tab, so your file never leaves your device. You can open your browser's network panel and watch: nothing carrying your file is sent.
Is there a file size limit?
No fixed limit. Because the work happens on your machine there is no server quota. The only ceiling is your own device's memory, which for video means very large files may be slow.
Will converting to OGV lose quality?
OGV is a lossy format, so some detail is discarded. The quality control on this page decides how much. The default is set high enough that most people cannot see the difference.
Can I convert several MPG files at once?
Yes. Add as many as you like and they are converted one after another, then offered as a single ZIP.
