AV1 to OGG Converter

Extract Audio from AV1 to OGG: Read This First

Here is the honest version, before you upload anything: a bare .av1 file is a raw AV1 video bitstream — by design it carries picture only, with no audio track inside. So if your goal is to pull a soundtrack out of an .av1 and save it as OGG, there is usually nothing to pull, and the output comes back silent or empty. The sound you heard almost certainly lived in a container (an .mp4, .mkv, or .webm) that wrapped the AV1 video next to a separate audio track. This page walks you through the tool, then shows you the routes that actually have audio to extract — and the one to use if you wanted the video all along.

How to Convert AV1 to OGG

1. Upload Your AV1 File: Drag and drop your .av1 onto the page, or click "+ Add Files" to browse. You can queue several files to process with the same settings.
2. Keep Vorbis or Switch the Audio Codec: Open "Show All Options." The .ogg target defaults to Vorbis; the Audio Codec dropdown also offers Opus, FLAC, and Speex. Leave it on Vorbis for game engines and legacy Ogg tooling.
3. Set Quality Preset, Bitrate, or Trim (Optional): Leave Quality Preset on the recommended setting, or switch File Compression to Custom Bitrate, Constant Bitrate, or Variable Bitrate to type an exact value. Audio Channel and Audio Sample Rate both default to Original, and Trim lets you export only part of the timeline.
4. Convert and Download: Click Convert and save your .ogg file. No sign-up, no watermark.

Walk-through: Why the Output Is Silent, and What to Convert Instead

The reason is the format, not the tool. AV1 is defined by the Alliance for Open Media as a video bitstream and nothing else — the spec was finalized on March 28, 2018 (validated as v1.0.0 in June 2018) and never describes audio. A file saved with a plain .av1 extension is normally a raw elementary stream: a sequence of AV1 Open Bitstream Units (OBUs), sometimes inside a minimal IVF wrapper, with no container around it to hold a parallel audio track. There is simply no soundtrack inside to decode, so any OGG produced from a genuine bare .av1 will be empty.

To actually get audio, convert the container the AV1 video was demuxed from — that is where the sound (most often Opus or AAC) still lives:

• If the source is an .mp4, use MP4 to OGG.
• If the source is a Matroska file, use MKV to OGG.
• If the source is a .webm, use WebM to OGG.
• If you wanted the picture kept, not just the audio, wrap the stream as a playable video with AV1 to MP4 instead.

There is a small irony worth noting: AV1 and Vorbis are cousins from the same open, royalty-free codec world — AV1 from the Alliance for Open Media, Vorbis (and its successor Opus) from the Xiph.Org Foundation. An AV1 video and an Opus or Vorbis soundtrack belong together naturally; it is only the bare, container-less .av1 that leaves the audio behind.

Common Errors and How to Fix Them

• "My OGG downloaded but plays nothing / is empty." The input was a true raw .av1 stream with no audio. Convert the original container instead (MP4 to OGG, MKV to OGG, or WebM to OGG).
• "I actually wanted to keep the video." OGG is audio-only — the picture is discarded by design. Use AV1 to MP4 to keep a playable video.
• "My OGG won't play on my iPhone or Mac." Apple added native Ogg Vorbis playback to Safari only recently (around Safari 18.4 / iOS 18.4); older Apple devices need a third-party player like VLC. For maximum reach, extract to MP3 from the container with MP4 to MP3 instead.
• "The file uploads but won't convert." A .av1 extension on a file that is really a full MP4/MKV/WebM can confuse detection. Re-save or remux it with its true container extension, then convert that.

When This Doesn't Work

If your .av1 is genuinely a raw, container-less bitstream, no tool — ours or anyone else's — can extract audio that was never inside it, and the right move is to go back to the container the clip came from. The same is true for DRM-protected or partially downloaded streams, which can decode as silent or corrupted regardless of the target format. When in doubt, convert the original .mp4, .mkv, or .webm you started with rather than a stripped-out .av1, and pick OGG only when your target specifically expects Ogg Vorbis.

Frequently Asked Questions

Why is my AV1 to OGG output silent or empty?

Because a raw .av1 file is an AV1 video elementary stream and holds no audio. AV1 is defined by the Alliance for Open Media as a video-only codec — its bitstream, finalized in March 2018, describes picture and never defines sound — so there is no soundtrack inside a bare .av1 to decode, and any OGG produced from it will be empty. The audio for that footage lived in the container it was demuxed from. To get sound, convert that container instead: MP4 to OGG, MKV to OGG, or WebM to OGG.

Is there such a thing as "AV1 audio"?

No. AV1 (AOMedia Video 1) encodes picture, not sound. When a file is described as "AV1," the audio riding alongside it is a separate stream encoded with a different codec — most commonly Opus or AAC — carried in an MP4, WebM, or Matroska container. Pull that existing audio out by converting the container, not the bare stream.

Should I use OGG Vorbis or Opus for this audio?

Opus is the technically stronger choice for a new project — since February 2013 the Xiph.Org Foundation has recommended Opus over Vorbis, and Opus holds quality better at low bitrates. The reason to still pick .ogg Vorbis is compatibility: many game engines and their importers, internet-radio stacks, and older Linux applications expect Vorbis-in-Ogg specifically. If your target understands the newer codec, switch the Audio Codec dropdown to Opus before converting.

Will my OGG file play on an iPhone, iPad, or Mac?

Not reliably on older Apple hardware. Ogg Vorbis has played natively in Chrome, Firefox, Edge, Opera, and VLC for years, but Apple only added native Ogg Vorbis playback to Safari very recently (around Safari 18.4 / iOS 18.4), and earlier versions do not handle .ogg without a third-party player. If your target is the Apple ecosystem or any older device, extract to MP4 to MP3 from the container instead, which plays virtually everywhere.

Is OGG Vorbis really patent-free, like AV1?

Yes, and the two share that open lineage. Vorbis is published as an open specification by Xiph.Org (the Vorbis I spec dates to 2002) and is distributed royalty-free; AV1 is published by the Alliance for Open Media and is likewise open and royalty-free. As with any codec the patent-free claim is the maintainer's position rather than a legal guarantee, but in practice both have been used commercially without licensing fees, which is exactly why open-source and game pipelines reach for them.

How are my files handled, and are they kept private?

Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after conversion — never shared or made public. There is no sign-up and no watermark. In our testing, a real .mp4 or .webm container with an Opus track produced a normal OGG at the selected quality, while a genuine raw .av1 elementary stream yielded a silent file regardless of the bitrate chosen — the format, not the pipeline, decides whether there is audio to extract.
