OGV to M4V Converter
Processing entirely on your device — large files may take a moment.
Ogg Video and iTunes Video exist for different jobs: OGV is the open-source Ogg video container (Theora) from early HTML5 video days — rare today but still produced by some Linux tools. Converting M4V to MP4 removes the compatibility friction while keeping quality.
Because the whole conversion happens on your device, it is instant, unlimited and genuinely private — no accounts, no watermarks, no files on anyone's server. Multiple files are converted in one go.
How OGV compares to M4V
| OGV | M4V | |
|---|---|---|
| Compression | Theora + Vorbis | Same as MP4 |
| Quality | Outdated codec | Same as MP4 |
| Compatibility | Open-source stacks | Apple ecosystems |
| Best for | Open-source era archives | iTunes video content |

About the OGV format
OGV is video in the Ogg container, historically paired with the Xiph Foundation's Theora codec. Around 2004–2010 it was the royalty-free answer to patent-encumbered H.264, pushed by Firefox and Wikipedia. Theora's compression has since been left far behind by VP9, AV1 and even H.264, and OGV files in the wild are almost exclusively period pieces.
If you encounter one, it decodes in VLC and Firefox-derived stacks fine; converting to MP4 or WebM brings it into the modern era with a quality-neutral remux/re-encode.
+ Strengths
- ✓Fully open-source lineage
- ✓Plays in Firefox-family and VLC
! Limitations
- −Theora compression is a generation behind
- −Near-zero modern ecosystem support
About the M4V format
M4V is Apple's variant of MP4, distinguished by an optional DRM layer (FairPlay) used by iTunes movie purchases, plus chapter flags. A DRM-free M4V is byte-for-byte the same beast as MP4 — rename the extension and most players never notice. Apple TV, iTunes and QuickTime treat it as first-class.
Outside Apple's world it buys you nothing: DRM-protected files are locked to authorized devices by design, and non-protected ones are just MP4. Converting M4V to MP4 is only meaningful to drop the extension or to strip DRM you are entitled to remove in your own jurisdiction — DRM-locked store purchases remain locked.
+ Strengths
- ✓Native to iTunes/Apple TV/QuickTime
- ✓Chapters and metadata for video series
- ✓DRM-free files equal MP4 in every way
! Limitations
- −Store purchases are DRM-locked to Apple devices
- −Redundant with MP4 outside Apple ecosystems

Frequently asked questions
Is this OGV to M4V converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Is there a file size limit for OGV to M4V?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
Does converting OGV to M4V re-encode my video?
Yes. The video is decoded and re-encoded with the settings chosen by the quality slider, which is what allows the format and size to change. For an archival copy, keep higher quality; for sharing, lower quality gives a much smaller file.
Will the audio track be kept?
Yes. The audio is carried over and re-encoded to the standard audio codec of M4V, staying in sync with the video. If your OGV file has multiple audio tracks, the first one is used.
