AV1 to OGA Converter

Convert AV1 to OGA: Read This First

A bare .av1 file is a raw AV1 video bitstream — by design it carries picture only, with no audio track inside it. So if your goal is to pull a soundtrack out of an .av1 and save it as OGA (the audio-only flavour of the Ogg container), there is usually nothing to pull: the resulting file would be silent. This page is honest about why, shows how the converter behaves, and points you to the file that actually holds your audio.

Why a Raw AV1 File Has No Sound

AV1 is the video codec from the Alliance for Open Media, whose bitstream specification was released in 2018. That specification describes a video codec built from Open Bitstream Units (OBUs) — it defines nothing about audio. A file saved with a plain .av1 (or .obu, or .ivf) extension is normally a raw elementary stream: a sequence of coded AV1 video frames and nothing else. There is no container around it to hold a parallel audio track, so there is no sound to decode.

The AV1 video you watched with sound almost certainly lived inside a container — a .webm, .mkv, or .mp4 — that wrapped the AV1 video next to a separate audio track (usually Opus, sometimes AAC). When a file is exported or demuxed down to a bare .av1, that audio is left behind. OGA, meanwhile, is an audio-only Ogg container from Xiph.Org that stores Vorbis (or Opus, FLAC, or Speex) audio. If you ran this conversion and got a silent OGA, that is not a bug in the converter — it is the raw AV1 stream doing exactly what the format specifies.

Note: .av1 here means an AV1 video bitstream. It is not the same as AVIF, which is a still-image format that also uses AV1 frames. This page is about the video stream.

How to Convert AV1 to OGA

1. Upload Your AV1 File: Drag and drop your .av1 onto the page, or click "+ Add Files" to choose it from your computer. You can queue several files to process with the same settings.
2. Set the Quality Preset or Bitrate: Open Advanced Options. The output codec is Vorbis. Leave Quality Preset at Highest, or switch to Custom Bitrate / Constant Bitrate (for example 128, 192, or 256 kbps) for an exact rate. Specific file size lets you target an output size in MB instead.
3. Set Audio Channel, Sample Rate, or Trim (Optional): Audio Channel and Audio Sample Rate both default to Original, which copies the decoded audio untouched. Force a value such as mono or 44100 Hz only if a target needs it, and use Trim to keep just a start time and duration.
4. Convert and Download: Click "Convert" and download your OGA. No sign-up, no watermark.

Walk-through: Will Your AV1 File Actually Have Sound?

Whether you get audio depends entirely on what you actually uploaded, because the AV1 specification defines only video — any audio rides in the container alongside it. The common cases:

• A true raw .av1 elementary stream: This is video only. The same is true for .obu and .ivf dumps, which by design hold a single elementary video stream. An OGA made from any of these will be empty or silent — there is nothing inside to extract, and no setting can create a soundtrack that was never in the file.
• A container that was misnamed .av1: Occasionally a .webm or .mkv gets renamed with an .av1 extension. If your file is secretly a container with a real audio track, the converter will decode that track to Vorbis and write a valid OGA. But that is the exception, not the rule.
• You actually want the soundtrack of an AV1 video: then you are starting from the wrong file. Upload the full container — the .webm, .mkv, or .mp4 that holds both the AV1 video and the audio — to the matching tool below.

If you are not sure whether your file is a bare stream or a container, check the extension: .av1, .obu, and .ivf are video-only elementary streams, while .webm, .mkv, and .mp4 can carry both video and audio together.

Where Your Audio Probably Is

• The original download or recording: the playable file you started from is almost always a .webm, .mkv, or .mp4. That container holds the audio — convert that file, not the demuxed .av1.
• A WebM container: AV1 video is most often paired with Opus audio inside WebM. Use WebM to OGA to pull that soundtrack into an Ogg Vorbis file.
• An MP4 container: use MP4 to OGA to decode the audio track from an MP4 (which can carry AV1 video) into OGA.

When This Doesn't Work

If your AV1 file is a true elementary stream with no companion audio, no tool can manufacture sound that was never encoded — the fix is to find the original container or the separate audio file. And keep one thing in mind even when audio is present: video containers normally store audio as a lossy codec such as Opus or AAC, so re-encoding it to Vorbis stacks a second lossy step. It will sound transparent at a healthy bitrate, but it is not a quality upgrade over the source. If you only want the video in a playable package rather than its audio, transcode the bare stream with AV1 to WebM to make it playable, or use AV1 to MP4 for a broadly compatible container.

Frequently Asked Questions

Why is my AV1 to OGA output silent or empty?

Because a raw .av1 file is an AV1 video elementary stream and holds no audio. There is no soundtrack inside the file to decode, so any OGA produced from a bare .av1 will be silent. The audio for that footage lived in the container (a .webm, .mkv, or .mp4) the video was demuxed from. Convert that container to OGA instead.

Does an .av1 file contain audio I can extract?

Normally no. AV1, the video codec from the Alliance for Open Media, defines only video, and a plain .av1, .obu, or .ivf file is a raw video bitstream with no audio track. You only get sound out if the file you uploaded is actually a container (such as a WebM misnamed .av1) that happens to carry an audio track alongside the video.

Is OGA the same as OGG?

They are the same Ogg container with different extensions. Xiph.Org registers .oga for audio-only files and .ogg for general Ogg use, both under the audio/ogg MIME type, so the audio bytes are identical — only the extension and OS hint differ. If your container genuinely has audio and you specifically need the .ogg extension, use our AV1 to OGG converter instead.

Is an .av1 file the same as an AVIF image?

No. AVIF is a still-image (and image-sequence) format that stores AV1-coded frames inside an ISO base media container, whereas a bare .av1 is a raw AV1 video elementary stream. They share the AV1 frame coding but are different file types — this converter expects the video bitstream, not an AVIF image.

Which browsers and players support OGA out of the box?

Ogg Vorbis audio plays natively in Chrome, Firefox, and Edge, and reaches about 95% of browsers globally per caniuse. Apple devices had no native Ogg support before Safari 18.4 / iOS 18.4, so older iPhones and iTunes will refuse the file. Open-source players like VLC and Audacity handle OGA on every platform.

How do I get OGA audio from a video that actually has sound?

Start from a file that genuinely contains an audio track. If your video is a WebM (the usual home for AV1 video), use WebM to OGA; if it is an MP4, use MP4 to OGA. Both formats interleave video and audio, so the converter has a real audio track to decode into Vorbis. A bare .av1 stream does not.

Is this AV1 converter free and private?

Yes. There is no sign-up and no watermark. In our testing, a misnamed WebM-as-.av1 with an Opus track decoded cleanly to a Vorbis OGA at the Highest preset, while a true raw .av1 stream produced an empty audio file — exactly as the format dictates. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after conversion — never shared or made public.
