Why convert OGV to MOV?

macOS rejects Ogg/Theora across the board — QuickTime Player won't preview .ogv, Final Cut Pro and iMovie won't import it, and macOS Preview shows a generic file icon. Converting to MOV with H.264 + AAC unlocks the entire Apple editing pipeline plus AirDrop sharing to iPhones (which also reject .ogv).

Will quality drop in the conversion?

Yes, slightly — Theora cannot be stream-copied into MOV (different codec family), so a one-time re-encode to H.264 at CRF 23 is required. CRF 23 is the FFmpeg default for visually lossless web/desktop quality; for normal screen viewing the result is indistinguishable from the source. H.264 is also far more efficient than Theora, so MOVs are usually smaller than the input OGV.

How fast is the conversion?

H.264 encoding in FFmpeg WASM runs around 0.8-1.5x realtime on a modern laptop — much faster than VP9. A 5-minute OGV typically converts in 4-7 minutes. Theora decoding is fast; H.264 encoding is the bottleneck.

What about the audio?

Vorbis audio is re-encoded to AAC at 192 kbps (MOV's standard audio codec). AAC is required for QuickTime / iMovie / Final Cut compatibility. Sample rate is preserved.

Are my files uploaded?

No. FFmpeg WebAssembly runs entirely in your browser. The OGV is decoded and the MOV is encoded locally — files never leave your device.

Convert OGV to MOV

Convert OGV (Ogg-Theora) video files to MOV (QuickTime) format directly in your browser. macOS-native tools — Final Cut Pro, iMovie, QuickTime Player, Preview — refuse to open OGV. MOV with H.264 and AAC is the universal Mac editing format. No upload needed.

When to Convert OGV to MOV

Converting OGV lecture recordings from Linux screencast tools to MOV for editing highlights in iMovie on macOS
Migrating OGV downloads from Wikimedia Commons to MOV for ingest into Final Cut Pro / DaVinci Resolve
Preparing OGV training clips as MOV for AirDrop sharing from Mac to iPhone (which refuses .ogv)
Converting OGV archive footage to MOV before importing into the macOS Photos library (which rejects Ogg)
Re-encoding OGV community videos to MOV for inclusion in Keynote / Pages presentations on macOS

//how_it_works

How It Works

Drop your OGV files

Drag and drop or pick .ogv files. First conversion loads FFmpeg WASM (~30MB).

FFmpeg decodes Theora + Vorbis

FFmpeg WASM parses Ogg pages and decodes Theora video frames and Vorbis audio packets to raw samples.

Encode H.264 + AAC

Video is re-encoded with libx264 at CRF 23 and audio with AAC-LC at 192 kbps, then muxed into MOV atoms.

Download MOV files

MOVs open natively in QuickTime, Final Cut Pro, iMovie, Premiere, DaVinci Resolve, and macOS Preview.

// under the hood

OGV is an Ogg container carrying Theora video and Vorbis audio. MOV is Apple's atom-based QuickTime container (the basis for MP4). Our converter uses FFmpeg WASM to decode Theora and Vorbis, then re-encode with libx264 at CRF 23 (visually lossless) and AAC-LC at 192 kbps, muxed into MOV atoms.
