M2TS to OGG Converter

M2TS to OGG Converter

This tool pulls the audio track out of an M2TS file — a Blu-ray rip or an AVCHD camcorder clip — and saves just the sound as a .ogg file, discarding the H.264, MPEG-2, or VC-1 video. M2TS is the BDAV transport-stream container that disc and camcorder audio lives in; OGG is the open, royalty-free Xiph.Org container that holds a Vorbis audio stream by default. The two tables below lay out what each format is before the short how-to, because whether this extraction is a clean encode or a lossy-to-lossy transcode depends entirely on which codec your M2TS happens to carry.

How to Convert M2TS to OGG

1. Upload Your M2TS File: Drag and drop your .m2ts (Blu-ray) or .mts (camcorder) clip onto the page, or click "+ Add Files". Both are the same BDAV container, so the extraction is identical either way. Queue several clips to extract them in one batch with the same settings.
2. Pick a Quality Preset: Open Advanced Options and choose a Quality Preset under File Compression — Highest down to Lowest — or switch to Custom Bitrate, Constant Bitrate, or Variable Bitrate to set an exact rate. The Vorbis stream is the OGG default; for a stereo music track, the upper presets stay close to the source.
3. Set Audio Channel or Trim (optional): Leave Audio Channel and Audio Sample Rate on "Original" to copy what the source recorded, or pick Mono or Stereo to downmix. Use Trim to keep only part of a long recording.
4. Convert and Download: Click "Convert" and download your .ogg file individually or as a ZIP. No sign-up, no watermark.

Frequently Asked Questions

Does this keep the video, or just the audio?

Just the audio. This is an extraction: the H.264, MPEG-2, or VC-1 video inside your M2TS is discarded and only the soundtrack is written out as an OGG file. If you want to keep the picture too, convert M2TS to MP4 instead, which re-encodes both the video and audio into a single playable file.

Will the OGG sound better than the audio already in my M2TS?

It depends on which codec the M2TS holds, and the honest answer is usually no. AVCHD camcorder clips and many Blu-ray tracks carry Dolby AC-3 or DTS, which are already lossy — so extracting to Vorbis is a lossy-to-lossy transcode that can match but not exceed the source, never regaining detail the original codec discarded. Where a Blu-ray rip carries an uncompressed LPCM track or a lossless Dolby TrueHD / DTS-HD Master Audio track, extracting that to OGG is a clean first-generation Vorbis encode — the best Blu-ray case, the same quality you'd get encoding from a WAV master. Either way, keep the bitrate near the source to avoid adding noticeable new loss.

What does the .ogg extension actually mean, and is it Vorbis?

Here the .ogg you download is an Ogg container holding a Vorbis audio stream, which is what almost everything means by an "OGG file". Ogg is just the wrapper — the Xiph.Org Foundation also defined Opus, FLAC, and Speex streams that can ride inside it. Since 2007 Xiph has recommended .oga for audio-only Ogg files and .ogv for video, but in practice .ogg stayed the extension most players and game engines expect for Vorbis sound, so that is what this tool produces. If you specifically want the newer Opus codec instead, extract to Opus packs the same perceived quality into a smaller file.

Can the OGG keep my Blu-ray's 5.1 or 7.1 surround sound?

Not as surround here. M2TS audio can carry up to 5.1 (AC-3, DTS) or even 7.1 (Dolby TrueHD, DTS-HD), but the Audio Channel control offers Original, Mono, and Stereo, so a multichannel mix is most reliably handled as a stereo downmix — which loses the spatial separation between the channels. There is no surround-preserving OGG output on this page. If keeping every channel matters, which is common with Blu-ray rips, extract to AAC instead, where multichannel is the supported path.

Why pick OGG over MP3 for an extracted soundtrack?

Two reasons. First, license: Vorbis is royalty-free and patent-unencumbered, which is why open-source game engines and web players adopted it — there were never licensing fees attached the way there historically were with MP3. Second, efficiency: at low-to-mid bitrates (roughly 96-192 kbps) Vorbis tends to sound slightly cleaner than MP3 at the same rate. The trade-off is reach — OGG plays in Chrome, Firefox, Edge, modern Safari, VLC, and Android, but a long tail of older car stereos and hardware players only handle MP3. If you need a file that plays virtually everywhere, extract to MP3 is the safer default.

Will a .ogg file play in Safari or on an iPhone?

Only on recent versions. Apple was the last major holdout: desktop Safari didn't play Ogg Vorbis until 14.1 (partial) and only fully from Safari 18.4, and iOS support arrived in the same recent window. Chrome, Firefox, Edge 17+, VLC, and Android have handled Vorbis for years. So an OGG is a safe choice for web and Android playback but a risky one if your audience is on older Apple hardware — in that case MP3 avoids the problem entirely.

How are my files handled, and is there a size limit?

Your M2TS file is uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after conversion — no sign-up, no watermark, never shared or made public. In our testing, the main practical limit is upload size and time rather than the extraction itself: an M2TS carries full HD video alongside the audio, so a long Blu-ray title or recording can take a while to upload even though pulling out the soundtrack is quick. For the same workflow straight from a camcorder's card folder, AVCHD to OGG covers extracting from the AVCHD stream files.
