Add your OGV file
Drop one or more .ogv files onto the converter above, or browse for them. They load into browser memory only — nothing is uploaded, so there is no size-based pricing and no server queue.
Pulling the soundtrack out of a .ogv video into .m4v audio keeps what you can hear and drops the picture entirely. Free, private, and validated — the file never leaves your browser.
Batch files can each use a different output. Nothing uploads for local conversions.
Working inputs include camera RAW, browser-local audio/video, PDF, CBZ/CBR comics, office documents, ebooks, markup, 3D models, structured text, images, and archives.Pulling the soundtrack out of a .ogv video into .m4v audio keeps what you can hear and drops the picture entirely. An .ogv file is video packed in the Ogg container, typically compressed with the Theora codec and paired with Vorbis audio. The .ogv extension separated video from Ogg audio when Xiph.Org split its file naming, and it appears mostly in open-source projects and Wikipedia's media archives.
An .m4v file is Apple's flavor of the MPEG-4 container, used by iTunes for movies, TV episodes, and music videos. Structurally it is almost identical to .mp4, but the .m4v extension signaled iTunes-specific features such as chapter markers and, on purchased content, FairPlay copy protection. For this route the practical draw is a DRM-free .m4v is a plain MP4, so a rename alone often fixes compatibility and carries chapters and artwork more gracefully than most containers — balanced against fairPlay-protected files play only in Apple apps on authorized devices, and no converter can open them, which is worth knowing before you commit a large batch.
The usual reason to take .m4v audio out of a .ogv file is that only the sound matters — a talk, interview, song, or podcast segment. Keeping the video stream would waste storage, and a dedicated audio file is easier to trim, tag, and play. On the source side, theora's compression is a full generation behind even VP8; on the target side, the payoff is a DRM-free .m4v is a plain MP4, so a rename alone often fixes compatibility, which is exactly what you want for playing back iTunes-era video libraries.
| Aspect | Ogg video (.ogv) | MPEG-4 video (.m4v) |
|---|---|---|
| Format type | Container — quality depends on the codecs and settings inside | Container — quality depends on the codecs and settings inside |
| How it stores data | uses Ogg's page-and-packet framing, which supports live streaming and survives truncation gracefully | identical ISO base media layout to MP4, distinguished only by branding atoms and the extension |
| Strongest at | playing media downloaded from Wikimedia Commons | playing back iTunes-era video libraries |
| Weak spot | theora's compression is a full generation behind even VP8 | fairPlay-protected files play only in Apple apps on authorized devices, and no converter can open them |
| Metadata | vorbis comments in the audio stream carry artist and title tags, and the Ogg Skeleton track can describe the streams themselves | full iTunes atom metadata: title, show, season, episode, artwork, chapters, and content ratings |

Select .m4v in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if M4V is selectable, the route is real and validated.
Press Convert. A WebAssembly FFmpeg build demuxes the audio track and re-encodes it locally; the video stream is simply discarded.
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid M4V file. Outputs keep the original filename with the .m4v extension.
Since ogv is container-oriented and m4v is container-oriented, the conversion preserves the source content exactly as stored; no additional compression pass is applied beyond what .m4v itself requires.
Yes — the .ogv file is processed inside your browser tab and never uploaded. A WebAssembly FFmpeg build demuxes the audio track and re-encodes it locally; the video stream is simply discarded. Close the tab and the file is gone from memory.
Apple devices treat .m4v as native, and most other players accept the file after inspecting its contents or following a rename to .mp4. The exception is DRM-protected iTunes video, which remains locked to Apple's own apps.
Much smaller — the video stream is usually 80–95% of a .ogv file's weight, and it is discarded entirely. The remaining audio is re-encoded at the bitrate implied by your quality setting.
This converter strips container metadata deliberately (the FFmpeg command runs with metadata mapping disabled) so exported files do not leak recording details. In the source, vorbis comments in the audio stream carry artist and title tags, and the Ogg Skeleton track can describe the streams themselves; none of it is transmitted anywhere because the file never leaves your browser.
Yes — the reverse route exists as a separate tool. Bear in mind that round-tripping .ogv → .m4v → .ogv is not a perfect undo when any lossy step is involved; keep your original if fidelity matters.
