MOV to OGV Converter

How to Convert MOV to OGV Online

1. Upload Your MOV File: Drag and drop or click "Add Files" to select MOV (QuickTime) files. iPhone recordings, ProRes exports, screen captures, and Mac-recorded video all work. Batch is supported — drop in an entire folder of clips.
2. Pick Theora Codec and Quality: Default is Theora (the only video codec OGV supports) paired with Vorbis audio. Choose a quality preset (Highest → Very High → High → Medium → Low → Lowest), target a percentage of the original size, set an exact size in MB, or fine-tune with the Theora-specific CRF range (0-10 quality scale, where 10 is highest). For audio, swap Vorbis for Opus, FLAC, or MP3.
3. Resize or Trim (Optional): Pick a resolution preset (1080p / 720p / 480p / 360p / 240p), enter a custom width × height, scale by percentage, or trim using start time + duration in HH:MM:SS.sss format. Keep aspect ratio with autoscale.
4. Convert and Download: Click Convert. Files process in your browser session — no sign-up, no watermark, no upload to a third-party server.

Why Convert MOV to OGV?

MOV is Apple's QuickTime container, ubiquitous on iPhones, iPads, and Macs but tied to proprietary codecs (H.264, HEVC, ProRes) that carry patent licensing. OGV (Ogg Theora) is the Xiph.Org Foundation's fully open-source video format — Theora video in an Ogg container, royalty-free since 2002, with no patent encumbrances. Common reasons to convert MOV → OGV:

• Wikipedia and Wikimedia Commons uploads — Wikipedia's policy permits only patent-free formats. Ogg Theora and WebM are accepted; H.264-based MOV is not. Anyone contributing video to a Wikipedia article or Commons gallery converts to OGV (or WebM) first.
• Open-source software demos and documentation — GNU, FSF-aligned projects, and Linux distros that refuse non-free codecs (Fedora, Trisquel, Debian main) ship Theora as the only video format their package repos allow.
• Royalty-free commercial streaming — H.264 and HEVC require MPEG-LA licensing for paid distribution. Theora has zero licensing fees for any commercial use, which matters for embedded video in apps, kiosks, and educational platforms with millions of plays.
• Legacy Firefox and Linux playback — Firefox shipped native Theora support since 3.5 (2009), and Linux distributions play OGV out of the box without proprietary codec packs. MOV requires VLC or extra QuickTime libraries.
• Archival in patent-free formats — Long-term preservation projects (Internet Archive's older video uploads, library digitization) often pick Theora because the format will never be encumbered by future licensing claims.
• Educational and academic publishing — Universities with patent-free media policies, MIT OpenCourseWare-style projects, and open educational resources commonly distribute lectures as OGV.

Frequently Asked Questions

Why is my OGV file larger than the original MOV?

Theora is an older codec (frozen in 2009) and is less efficient than H.264 or HEVC found inside modern MOV files. At equal visual quality, expect OGV to be 30-60% larger than an H.264 MOV. If file size matters more than patent-freeness, WebM with VP9 or AV1 is smaller and still royalty-free.

Will Safari users play my OGV?

No. Safari has never shipped native Theora support on macOS or iOS. If your audience includes Safari users, embed a fallback <source> tag with WebM or MP4. For Wikipedia uploads this isn't an issue — Wikimedia transcodes OGV to WebM server-side for Safari visitors.

Should I keep Vorbis or use Opus for audio?

Vorbis is the historical Ogg audio codec and the safe default for OGV — it has the broadest player support (Firefox, VLC, Linux media stacks). Opus is newer and more efficient (better quality at lower bitrate) and is supported in modern OGV-compatible players, but a few older Theora-only tools may stumble on it. Pick Vorbis for maximum compatibility, Opus for best quality-per-byte.

Can I convert iPhone MOV recordings to OGV?

Yes. iPhone records MOV with H.264 or HEVC video — both transcode cleanly to Theora. 4K iPhone footage produces large OGV files (Theora isn't built for 4K efficiency); consider downscaling to 1080p or 720p first, or use MOV to WebM instead if file size is critical.

What's the Theora CRF / qscale scale?

Theora uses a 0-10 quality scale (the FFmpeg -qscale:v parameter), where 10 is the highest quality and 0 is the lowest. This is inverted from H.264's CRF (where lower is better). The default preset maps to qscale 7, which is visually excellent for most content. Push to 9-10 for archive masters, drop to 4-5 for web tutorials.

Does OGV support subtitles?

The Ogg container supports subtitle streams via Kate (Karaoke and Text Encapsulation), but adoption is thin. Most OGV players ignore embedded subtitle tracks. For Wikipedia, distribute subtitles as a separate .srt file alongside the video — TimedText handles the rest.

Will my Apple ProRes MOV convert correctly?

Yes. ProRes inside MOV decodes fine; the output Theora is a re-encode (ProRes → Theora isn't a "wrap" — different codecs entirely). Expect significant quality loss if you're going from a 200 Mbps ProRes master to a 5-8 Mbps Theora output. Use the Highest quality preset and 1080p resolution to preserve as much of the master as possible.

What's the file size limit?

XConvert handles large MOV inputs including multi-GB recordings. Conversion runs in your browser, so the practical ceiling is your device's available memory and your patience for the upload. Theora encoding is single-threaded and slower than H.264, so expect 2-4× longer encode times than MOV to MP4 for the same file.

Can I batch convert multiple MOV files to OGV?

Yes — drop in folders of QuickTime exports, iPhone recordings, or screen captures. They convert in parallel within your browser session and download individually or as a single ZIP. Same Theora settings apply to every file in the batch.
