Need help?Extract Audio from MOV to OGA Online
This tool pulls the audio track out of a MOV video and saves it as an OGA file — the Ogg container used for audio. The video is discarded; only the sound is kept. OGA is open and royalty-free, so it plays natively in Firefox, Chrome, and Edge without any proprietary codec, which makes it a good fit for the web and open-source media players. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after conversion — no sign-up, no watermark.
How to Convert MOV to OGA
- Upload Your MOV File: Drag and drop your MOV onto the page, or click "+ Add Files" to browse. You can queue several clips and convert them with the same settings.
- Pick the Audio Codec: Open Advanced Options and set Audio Codec to Vorbis (the default), Opus, or FLAC. Vorbis and Opus are lossy; FLAC keeps the audio lossless at a larger size.
- Set Quality or Bitrate (Optional): Use the Quality Preset (defaults to Highest), or switch to Custom Bitrate for an exact rate. Audio Channel, Audio Sample Rate, and Trim are left unchanged unless you adjust them.
- Convert and Download: Click "Convert" and save your OGA file. No sign-up, no watermark.
Choosing a Codec for Your OGA File
A MOV usually stores its audio as AAC (sometimes PCM or ALAC). Going from that to Vorbis or Opus is a lossy-to-lossy transcode, so keep the quality high to avoid stacking up artifacts. Pick FLAC only if you want a faithful, lossless copy.
| Codec inside OGA | Type | Best for | Notes |
|---|---|---|---|
| Vorbis | Lossy | General web audio, broad player support | OGA default; v1.0 released May 2000 by Xiph.Org |
| Opus | Lossy | Speech, podcasts, low-bitrate streaming | More efficient than Vorbis at low bitrates; RFC 6716 (2012) |
| FLAC | Lossless | Archiving the audio with no quality loss | Larger files; exact copy of the source samples |
Frequently Asked Questions
Is OGA the same as OGG?
They are the same Ogg container with different file extensions. The Ogg spec registers .oga for audio-only files and .ogg for general use, both under the audio/ogg MIME type. Renaming an .oga file to .ogg does not change the data inside. If you specifically need the .ogg extension, use our MOV to OGG converter instead.
Will I lose quality extracting MOV audio to OGA?
The audio in a MOV is usually already lossy (AAC), so re-encoding it to Vorbis or Opus is a lossy-to-lossy step that can shed a little more quality. Keeping the Quality Preset at Highest, or choosing a bitrate at or above the source, keeps the loss inaudible in most cases. Choose the FLAC codec if you want a lossless result with no further degradation.
Which browsers and players support OGA out of the box?
Ogg Vorbis and Opus audio play natively in Chrome, Firefox, and Edge, and in Safari 18.4 and later. Vorbis playback reaches about 95% of browsers globally. Open-source players such as VLC and Audacity handle all three codecs (Vorbis, Opus, FLAC) on every platform.
Vorbis or Opus — which should I pick for OGA?
For low-bitrate speech and podcasts, Opus is the more efficient codec and the Xiph.Org Foundation has recommended it over Vorbis for new projects since 2013. For general music and the widest player compatibility, Vorbis is a safe default. In our testing, a typical spoken-word MOV re-encoded to Opus in OGA came out noticeably smaller than the same clip as Vorbis at equivalent quality.
Is OGA royalty-free?
Yes. Vorbis, Opus, and FLAC are all open formats from the Xiph.Org Foundation with no licensing fees or known patent restrictions, which is why OGA is common in Linux distributions, Firefox, and open-source projects. If you later need a more universally compatible audio file for older hardware, convert it to MP3 with our MOV to MP3 tool.
