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 a Video Codec and Quality: Default is VP8 video paired with Vorbis audio; switch the Video Codec to Theora if a legacy Ogg-only tool specifically expects the classic pairing. 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 the quality value (with Theora selected this is its 0-10 qscale, 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 are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — no sign-up, no watermark, never shared.

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 from 3.5 (2009) until version 126 disabled it by default, and Linux distributions still 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.

These qscale mappings apply when you switch the Video Codec to Theora; the VP8 default uses the same preset names.

Frequently Asked Questions

Why is my OGV file larger than the original MOV?

Both Ogg codecs offered here are less efficient than the H.264 or HEVC found inside modern MOV files — especially Theora, an older codec (bitstream frozen in June 2004; libtheora 1.0 stable released November 2008). At equal visual quality, expect the OGV to come out 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 the OGV output codec (VP8 by default, or Theora). 4K iPhone footage produces large OGV files (neither codec is 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). With Theora selected, the High 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 is a full re-encode into VP8 or Theora (not a "wrap" — different codecs entirely). Expect significant quality loss if you're going from a 200 Mbps ProRes master to a 5-8 Mbps OGV 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 on our servers, so the practical limit is upload size and connection speed and your patience for the upload. Ogg encoding is slower than H.264 — Theora in particular is single-threaded — so expect 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 on our servers and download individually or as a single ZIP. Same Theora settings apply to every file in the batch.
