Does my WEBM get uploaded to a server?

No. The conversion runs in your browser with WebCodecs, so your video never leaves your device.

Will the MOV play in QuickTime and Final Cut Pro?

Yes. WEBM uses VP9 or VP8 video, which Apple apps don't accept. The video gets transcoded to H.264 and the audio to AAC inside a QuickTime MOV container, which QuickTime, Final Cut Pro and iMovie open natively.

Why does a large WEBM take a while?

Converting means decoding and re-encoding every frame to H.264. Larger or longer clips have more frames, so they take a bit longer.

WEBM to MOV

Re-encodes your WEBM into a QuickTime MOV that carries H.264 video and AAC audio.

What this does

Convert WEBM video into a QuickTime MOV. The VP9/VP8 video is transcoded to H.264 and the audio to AAC inside a MOV container, entirely in your browser with WebCodecs.

How it works

1Drop your WEBM file or pick it from your device.
2Click Convert to MOV and watch the progress bar as it re-encodes.
3Download your MOV. It never leaves your browser.
