OGV to MOV Converter

OGV vs MOV — Which Should You Convert To?

If you are asking this question you almost certainly have a .ogv that a Mac will not open. That is not a broken file: .ogv is Xiph.Org's Ogg video profile, defined in RFC 5334, and the picture inside is normally Theora — a codec Apple has never shipped a decoder for. .mov is Apple's own QuickTime container, and it is what QuickTime Player, iMovie, Final Cut Pro and Safari expect.

The short answer: if the file is going anywhere near Apple software, convert it to MOV. If it is going onto a web page or into a general-purpose archive, MOV is the wrong destination and you want OGV to MP4 or OGV to WebM instead. Everything below is the detail behind that split.

Side-by-side Comparison

When OGV Is Still the Right File

• You are serving it to a controlled audience that you know runs a browser or player with Theora support, and licensing purity matters more than reach.
• It is an archival original. Keep the .ogv even after converting — every conversion here is a re-encode, so the source is the only copy that has not been through a second lossy pass.
• The destination is a system built specifically around royalty-free codecs. In that case the modern move is not to keep Theora but to go to OGV to WebM, which is still royalty-free but actually decodable in current browsers.

When to Convert to MOV

• QuickTime Player shows a "not compatible" error. Apple's own Xiph decoder route is gone: Xiph.Org announced that there will be no further releases of the XiphQT QuickTime Components, because the QTKit API they depend on was deprecated in OS X 10.9 and removed in macOS 10.12 — XiphQT only ever worked with QuickTime 7, never QuickTime X. There is no supported way to make a modern Mac play Theora in QuickTime.
• You need the clip on an iMovie or Final Cut timeline. Both import MOV natively and neither reads Ogg.
• You are handing footage to someone on macOS or iOS and cannot control what player they use.
• You want the clip to preview in Finder and Quick Look. An H.264 MOV thumbnails and scrubs there; an .ogv shows a generic icon.

How to Convert OGV to MOV

1. Upload Your OGV File: Drag your .ogv onto the page or click "Add Files" to browse. Several files can be queued and converted on identical settings.
2. Confirm Video Codec and Audio Codec: Advanced Options opens on H.264 video with AAC audio, which is the pairing every piece of Apple software decodes. H.265 is the smaller-file alternative; MJPEG plus PCM audio is the editing-friendly one.
3. Set Quality, Resolution or Trim (Optional): File Compression opens on Quality Preset at "Very High (Recommended)". Video resolution opens on "Keep original". If you switch Trim from "Unchanged" to "Time Range", note that Duration is pre-filled at 10 seconds — set it to the real length you want or the output will be a ten-second clip.
4. Convert and Download: Click Convert and save the .mov. No sign-up, no watermark.

Codec Choices Inside the MOV

MOV is a container, so what actually determines compatibility is the payload. The Video Codec dropdown lists 18 entries and the Audio Codec dropdown lists 15, which is wider than the set QuickTime treats as native — an explicit selection is passed to the encoder rather than being re-checked against the container, so a fringe choice can produce a file Apple software still refuses. Stick to this table.

There is no ProRes option on this page — ProRes is an Apple codec that our pipeline does not encode. If your editor specifically requires ProRes, convert to H.264 MOV here and transcode to ProRes inside Final Cut or Compressor, which do it properly.

Frequently Asked Questions

Why won't my OGV open in QuickTime, iMovie or Final Cut?

Apple has never shipped an Ogg Theora decoder, and the third-party fix is dead. Xiph.Org's XiphQT QuickTime Components were the historic way to add Theora and Vorbis to a Mac, and Xiph has stated there will be no new releases: the components relied on QTKit, which Apple deprecated in OS X 10.9 and removed in macOS 10.12, and they only ever worked under QuickTime 7 rather than QuickTime X. Converting the container and codec is the only route that works on a current Mac.

Will converting OGV to MOV lose quality?

A little, unavoidably. Theora and H.264 are different codecs, so the video is decoded and re-encoded rather than copied — our server has no stream-copy path. That is one fresh lossy generation on top of footage Theora had already compressed. Leaving the Quality Preset on "Very High" keeps the difference invisible on most material; nothing on this page can recover detail the original Theora encode discarded.

Is the MOV bigger or smaller than the OGV?

Usually smaller at comparable quality, because H.264 is a substantially more efficient codec than Theora. It is not guaranteed — a very low-bitrate Theora source encoded at a high preset can grow. If you need a specific size, switch File Compression from Quality Preset to "Specific file size" and name the number.

Can I get ProRes out of this converter?

No. The Video Codec dropdown offers H.264, H.265, MPEG-4 and MJPEG among others, but not ProRes, and no online step here will produce a genuine ProRes file. The practical path is to convert to a high-quality H.264 MOV and let Final Cut Pro or Compressor transcode to ProRes on import — those tools have the licensed encoder.

Does the Vorbis audio in my OGV survive the conversion?

Not as Vorbis. MOV does not carry Vorbis, so the soundtrack is decoded and re-encoded — to AAC by default. That is a second lossy pass, generally inaudible on speech and web-quality music. If the audio is the important part and you want no further loss from this point on, pick PCM 16-bit or 24-bit Little Endian, which stores it uncompressed at the cost of a much larger file.

MOV or MP4 — which should I actually pick for an old .ogv?

MOV if the file is going into Apple software. MP4 for everything else: browsers, Android, social platforms, messaging apps and most editors read it directly, and it is the same H.264 payload in a container with wider reach. The two are close relatives — QuickTime's file format is the basis the MP4 specification was built on — so the picture quality is identical either way. OGV to MP4 is one click away if MOV turns out to be the wrong call.

Why did my output come back as a 10-second clip?

Because Trim was switched to "Time Range" and its Duration field is pre-filled with 10 seconds. It is easy to enable the trim, set a start time, and never notice the duration below it. Set Duration to the length you actually want, or switch Trim back to "Unchanged" to keep the whole clip.

Do modern browsers still play .ogv at all?

Effectively no. caniuse records Chrome disabling Theora by default from version 120 and removing it in version 123, Edge from 122, Opera from 106, and Firefox disabling it by default in version 126; Safari never supported it. FFmpeg and VLC still decode Theora, which is how your file is read here — but a .ogv embedded in a web page today will simply fail to play for nearly every visitor.

What happens to my files after converting?

Your .ogv is uploaded over an encrypted connection, decoded and re-encoded on our servers, and both the upload and the finished .mov are deleted automatically after a few hours. No sign-up, no watermark, and files are never shared or made public. For the opposite direction, see MOV to OGV.
