Is my video uploaded to convert it?

No. The conversion runs in your browser via ffmpeg compiled to WebAssembly — the file never leaves your device.

Will the quality drop?

The re-encode targets visually-near-source quality. For typical phone footage the result is indistinguishable; conversion here is about compatibility, not compression. If you also want it smaller, run Compress afterwards in the same studio.

Why do iPhones record MOV in the first place?

Apple's ecosystem uses the QuickTime container. The video inside is often already H.264 or HEVC — the container (and sometimes HEVC) is what other platforms choke on. MP4 with H.264 is the universal answer.

Does it handle HEVC (H.265) iPhone videos?

Yes — the video is re-encoded to H.264, which is exactly what makes it play on devices and browsers that lack HEVC support.

How long does it take?

Roughly real-time-ish on a modern laptop — a one-minute clip takes on the order of a minute. The work happens on your device instead of a server farm; that's the privacy trade, with a progress bar.

Is there a size limit?

Processing runs in browser memory, so practical limits depend on your device. Typical phone clips are fine.

MOV to MP4, no upload.

Drop an iPhone or QuickTime .mov and it is re-encoded to a universal MP4 on your device — never sent to a server.

Convert MOV to MP4 in your browser. MOV is what iPhones and Macs record — QuickTime's container — and it's exactly what Windows apps, Android phones, editors, and upload forms most often reject. Drop the file and GhostVideo re-encodes it to a standards-compliant MP4 (H.264 + AAC) on your device: plays everywhere, streams properly, uploads anywhere. No upload to us, ever — the conversion runs locally, which matters when the clip is your kid's birthday and not stock footage.

How it works

1
Drop your MOV
Drag in the .mov from your iPhone, Mac, or camera. It opens in the GhostVideo studio with Convert to MP4 pre-selected.
2
It re-encodes locally
ffmpeg runs in your browser and rebuilds the video as a web-standard MP4 — H.264 video, AAC audio, streamable layout.
3
Download the MP4
Save it — it now plays on Windows, Android, smart TVs, and every editor and upload form.
