OGV TO MP4
- Drag and drop your .ogv file or click to choose from your computer. Files over 1 GB are welcome. One video at a time.
- We are converting your OGV to MP4 (H.264 video + AAC audio). Large videos may take a little longer. Please keep this tab open.
- Your MP4 is ready. Click Download, then submit your next video if you have more to convert.

OGV to MP4 that plays everywhere
Upload an .ogv and Converter App will convert its Theora/Vorbis streams to MP4 with H.264 video and AAC audio for broad compatibility. If your OGV uses uncommon codecs or includes an alpha channel, we’ll flatten transparency and still try to map tracks accurately.

Built for big videos
Converter App handles large OGV files over 1 GB and outputs MP4s that play on phones, browsers, and TVs. Submit one video at a time and start the next as soon as your download finishes, with no daily caps.

It’s Free!
Converter App is free to use. No account, no watermark, and no hidden charges. We do not impose daily caps or queue limits beyond fair use.

How it works
Drop your .ogv or choose a file and we’ll transcode to MP4 using H.264 for video and AAC for audio. Keep this tab open for long jobs; subtitles or chapters in OGV may not carry over, but audio tracks and basic metadata are preserved when possible.

Quality preserved, no upscaling
We keep your original resolution and frame rate to maintain the look of your source; file size may grow or shrink depending on the bitrate and content. Theora-to-H.264 can render grain and motion a bit differently, and standard MP4 does not support transparency so alpha is flattened.

Privacy
Your files are processed only to perform the conversion. Transfers use encrypted connections. Source files and converted results are automatically removed from our servers shortly after the job completes. No sign-up is required, and we do not use your videos for anything else.
