OGV to AAC Converter

Extract AAC Audio from an OGV: What This Covers

.ogv is Xiph.Org's Ogg video container — the royalty-free format of the pre-H.264 web, still the download format behind a lot of Wikimedia Commons material and older Linux screen recordings. The video inside is usually Theora and the soundtrack is usually Vorbis, and neither plays reliably on Apple hardware or in a modern browser any more. This tool throws the video away and re-encodes only the audio as AAC, so what you download is a small .aac file rather than a video.

Before you touch the settings, one thing is worth knowing: this page offers four different ways to control the output rate, and they are not equally useful. The walk-through below says which to use and why.

How to Convert OGV to AAC

1. Upload Your OGV File: Drag the .ogv onto the page or click "Add Files" to browse. Several files can be queued and extracted with the same settings in one batch.
2. Set the Rate under File Compression: Use the Variable Bitrate dropdown for quality-targeted encoding, or Constant Bitrate, which starts on 128 kbps and runs from 8 kbps to 384 kbps. Custom Bitrate takes any figure in bps, Kbps or Mbps and opens at 128 Kbps.
3. Adjust Channels, Sample Rate or Trim (Optional): Audio Channel offers Original, Mono and Stereo; Audio Sample Rate offers Original plus 8000, 12000, 16000, 24000, 44100 and 48000 Hz. Trim exports a start time and a duration instead of the whole soundtrack — its duration field opens at 10 seconds.
4. Convert and Download: Click Convert and save the .aac. Files are uploaded over an encrypted connection, converted on our servers and deleted automatically after a few hours — no sign-up, no watermark.

Walk-through: Which Rate Control to Use

The five Variable Bitrate entries — 20k-32k, 32k-40k, 48k-56k, 64k-72k and 96k-112k — are the encoder's five VBR steps in order, from most compressed to highest quality. Treat those kbps figures as nominal guides rather than guarantees: a variable-rate encoder spends bits according to the material, so sparse content lands below its labelled band and dense content can run well above it. If you need a number you can predict before you convert, use Constant Bitrate.

Choosing a Bitrate

Because a Vorbis soundtrack is already lossy, this is a lossy-to-lossy transcode: nothing is regained, and the goal is simply to avoid adding audible loss. Matching or slightly exceeding the source bitrate is the reliable way to do that. Keep the original .ogv if full quality might matter later.

Common Errors and How to Fix Them

• "My .ogv will not play in Chrome or Firefox any more" — Google announced Theora's deprecation in October 2023, disabled it by default in Chrome 120 and removed it in Chrome 123; Firefox disabled it by default in version 126. That affects browser playback of the Theora video only. Standalone decoders still read the file, which is how the conversion works even when your browser refuses the source.
• "The .aac will not open in my music app" — The output is a raw ADTS AAC stream. VLC, foobar2000 and mpv handle it, but library apps often want AAC inside an MP4 container. Use OGV to M4A for a file that imports cleanly.
• "There is no video in the output" — That is the point of this tool: the picture is discarded and only the soundtrack is encoded. If you wanted a playable video, use OGV to MP4.
• "The output is only ten seconds long" — The Trim duration field opens at 10 seconds. Switching Trim on without changing it silently truncates the export. Set the duration you want, or leave Trim off.
• "The file sounds worse than the original" — Almost always a bitrate that is below the Vorbis source's. Re-run with Constant Bitrate set at or above the source rate, or move to the 96k-112k Variable Bitrate step.
• "The Quality Preset does not seem to change anything" — Use Variable Bitrate instead. It is the rate control on this page with named steps, so you can see exactly what you selected and reproduce it later.

When This Doesn't Work

Two cases fall outside this page. If the .ogv has no audio track at all — some screen captures and animation exports do not — there is nothing to extract and the conversion has no useful output; convert the video instead. And if the file is actually audio-only Ogg that someone mislabelled, you do not need the video step: OGG to AAC and OGA to AAC do the same job directly. For trimming, note that our audio cutter does not accept video input, so cut the source first with video-cutter or use the Trim control here.

Frequently Asked Questions

Why extract to AAC instead of just keeping the OGV?

Reach. Vorbis-in-Ogg is not supported by Safari at all and Theora has now been removed from Chrome, so an .ogv is increasingly a file that only specialist software opens. AAC is the format Apple devices, car head units, CarPlay and virtually every phone expect. Extracting also drops the video weight entirely, turning a video file into a small audio one — which is usually the actual goal when someone converts an OGV to an audio format.

Is AAC better than the Vorbis already inside my OGV?

Not meaningfully, on sound quality alone. Modern Vorbis and AAC are close at typical bitrates, and Vorbis has historically held up well at lower rates. The reason to convert is compatibility, not fidelity — and because this is a lossy-to-lossy transcode, the AAC can only be equal to or worse than the Vorbis, never better. If the destination already plays Ogg, there is no reason to convert at all.

What actually plays a bare .aac file?

The output is a raw ADTS AAC stream. VLC, foobar2000, mpv and most desktop and mobile players handle it without complaint. Browsers are less consistent: MDN notes that Chrome "supports AAC only in MP4 containers, and only supports AAC's Main Profile", that AAC "is not available in Chromium builds", and that Firefox relies on the platform's native AAC support rather than shipping its own. If you want a file that drops straight into a music library or a web page, use OGV to M4A — the same AAC audio inside an MP4 container.

Should I pick Variable Bitrate or Constant Bitrate?

Variable Bitrate unless something specific argues against it. It lets the encoder spend more bits on complex passages and fewer on simple ones, which is a better use of the same average size. Choose Constant Bitrate when a downstream system needs a predictable rate — a streaming pipeline, an embedded player, or a size calculation you have to do before converting.

My OGV's audio is not Vorbis — does that change anything?

Only the fidelity arithmetic. Ogg can also carry Opus, Speex or FLAC. Opus and Speex are lossy, so the transcode is still second-generation and the same "match the source rate" advice applies; Speex material is speech, so the low Variable Bitrate steps are plenty. FLAC-in-Ogg is lossless, which makes this a clean first-generation AAC encode — worth using the 96k-112k step or a high constant rate to preserve it.

Does converting remove the video permanently?

From the output, yes — the .aac contains an audio stream and nothing else, which is why it is a fraction of the size of the OGV. Your original file is untouched and still on your machine. If you wanted to keep the picture, OGV to MP4 is the conversion to run instead.

Which sample rate and channel settings should I leave alone?

Both, in most cases. Original passes the source's rate and channel layout straight through, which is what a faithful extraction wants. Change Audio Sample Rate only when a target device demands a specific figure, and Audio Channel only when you deliberately want a mono downmix — halving the channels roughly halves the data, which is a sensible trade for a single-voice recording and a bad one for music.

How are my files handled during the conversion?

Your .ogv is uploaded over an encrypted connection, processed on our servers and deleted automatically after a few hours — never shared, never made public, no sign-up and no watermark. Because a video upload carries the full picture stream, the wait is usually upload time rather than the extraction itself; only the small audio file comes back down.
