Convert WebM to MOV
Last updated: June 1, 2026To convert WebM to MOV, drop your WebM file into the converter above, then download the MOV result. It's free, needs no sign-up, and there's no watermark. Conversion runs in your browser with on-device FFmpeg, so your files never leave your device.
Why convert WebM to MOV?
Got a WebM that QuickTime, iMovie or Final Cut flatly refuses to open? Convert it to MOV right here, entirely in your browser. WebM wraps VP8/VP9 video and Opus audio that Apple software won't touch; this tool re-encodes those streams into a QuickTime-friendly MOV (H.264/AAC) using FFmpeg compiled to WebAssembly. Your file never uploads to a server and never leaves your device. It's free, with no sign-up, no watermark, and no file-size cap beyond what your machine can handle.
- You downloaded a WebM clip from a website and double-clicking it does nothing because QuickTime Player can't read the VP9/Opus codecs inside — converting to MOV makes it play instantly on your Mac.
- You're editing in Final Cut Pro, iMovie or Adobe Premiere and the WebM import fails or shows audio with no video — a MOV with H.264/AAC drops onto the timeline cleanly without proxy errors.
- You want to hand a web-recorded video (OBS, browser screen capture, a WebRTC export) to a Mac-using colleague and need a .mov that opens in Keynote, Photos and AirDrop previews without extra plugins.
WebM vs MOV
WebM · WebM (VP9)
WebM is an open, royalty-free format designed for the web. VP9 video gives smaller files than H.264 at similar quality and is ideal for embedding directly on a site.
MOV · QuickTime Movie
MOV is Apple's QuickTime container, the format iPhones and Macs record in. It's high quality but less portable than MP4 on Windows and Android.

Open Video ConverterWebM to MOV — frequently asked questions
Does converting WebM to MOV lose quality?
WebM (VP8/VP9) and standard MOV (H.264) are both lossy codecs, so re-encoding does involve one fresh compression pass. In practice the difference is hard to notice because the tool targets a high bitrate, and you're starting from web video that's already compressed. For true edit-grade quality you'd want a ProRes MOV, but for playback and most editing H.264 inside MOV looks essentially identical to the source.
Is my video safe — does the file get uploaded anywhere?
No. The entire conversion runs locally in your browser through FFmpeg compiled to WebAssembly. Your WebM is read straight from your device into memory, transcoded on your own CPU, and the MOV is handed back as a download. Nothing is sent to a server, nothing is stored, and the file never leaves your computer — which also means it works offline once the page has loaded.
Why won't QuickTime just play my WebM without converting?
QuickTime and the wider Apple ecosystem never shipped support for Google's VP8/VP9 video or Opus audio, which are exactly the codecs WebM uses. The .webm container itself is the blocker. Rewrapping and re-encoding into MOV with H.264 video and AAC audio gives QuickTime, iMovie and Final Cut a format they natively understand.
