OGV to MOV Converter

Convert OGV to MOV Online

OGV is the open-web video format — an Ogg container holding royalty-free Theora video, the kind Wikipedia and Wikimedia Commons hand out. The catch: Apple's QuickTime, iMovie, Final Cut, and Safari have never played Ogg Theora natively. This converter re-wraps and re-encodes your OGV into a MOV (Apple QuickTime container, H.264 video, AAC audio by default) so it drops straight into an Apple editing or playback workflow. Because Theora and H.264 are different codecs, this is a true re-encode — keep the Quality Preset high, since re-encoding can only preserve quality, never add it back.

How to Convert OGV to MOV

1. Upload Your OGV File: Drag and drop your .ogv file onto the page or click "+ Add Files". You can queue several files and convert them with the same settings.
2. Confirm Codec and Quality Preset: MOV output defaults to the H.264 video codec and AAC audio — the safest pair for Apple software. Under Advanced Options, leave the Preset on "Very High (Recommended)" to minimize re-encoding loss, or switch the Video Codec to H.265 or even ProRes-friendly options if your editor prefers them.
3. Resize or Trim (Optional): Use Video resolution to downscale (preset resolutions or a percentage), or use Trim's Time Range to export just one segment instead of the full clip.
4. Convert and Download: Click "Convert" and download your MOV. No sign-up, no watermark.

Frequently Asked Questions

Why won't my OGV file open in QuickTime or iMovie?

Apple software has never shipped the Ogg Theora decoder. QuickTime, iMovie, Final Cut, Safari, and iOS all lack native Theora support — historically you needed third-party Xiph QuickTime Components to play OGV on a Mac. Converting to MOV (H.264) sidesteps that entirely, because H.264 is decoded natively across the Apple ecosystem.

Will converting OGV to MOV lose quality?

Some loss is unavoidable because Theora and H.264 are different codecs, so the video is fully re-encoded rather than copied. A re-encode can preserve quality but never recover detail the source already lost. Keeping the Preset on "Very High" minimizes added artifacts; there is no quality benefit to using a lower preset for an archival copy.

What codecs does the MOV output use?

By default the MOV is written with H.264 video and AAC audio, which is the most broadly compatible combination for QuickTime, Final Cut, and iOS. If you need a different pairing, the Video Codec dropdown under Advanced Options also offers H.265 (HEVC), MPEG-4, and others, with matching audio codec choices.

Is the file size different after converting to MOV?

Usually smaller for equivalent quality. H.264 is a more efficient codec than Theora, so a MOV at the same visual quality typically lands at a smaller size than the original OGV. The exact result depends on your Quality Preset, resolution, and clip length — raising the preset or keeping full resolution increases the size.

How large an OGV file can I upload, and is it private?

There's no fixed file-count limit, and the practical ceiling is upload size and time rather than anything on your device. Files are 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. If you only need a short section, trimming first keeps the upload smaller and faster. For the reverse direction, see MOV to OGV.
