Accepts QuickTime (.mov) — including iPhone HEVC and H.264 footage

Why convert in your browser?

🔒

Your video never leaves your computer

Conversion runs on your computer — not on someone else's server. Zero uploads.

⚡

Lossless remux when possible

If your MOV file already contains H.264 video, we just rewrap it into an MP4 container — no re-encoding, no quality loss, near-instant.

🎬

HEVC / H.265 source supported

iPhone HEVC footage is ready in seconds as an MP4 that keeps its HEVC video. Need it to play everywhere? Convert it to H.264 at a visually lossless CRF 18.

🚫

No watermark, no signup, no caps

CloudConvert caps free users at 10 conversions/day. Zamzar limits at 50 MB. VEED watermarks. We don't do any of that.

📦

No file size limit

Drop a 4 GB drone clip if you want. The only limit is your device's available memory — there's no upload step to choke on.

🌐

Works offline after first visit

The engine downloads once, then runs forever. Turn off Wi-Fi to verify — conversion keeps working.

Common questions

Does this work with iPhone HEVC .mov files?

Yes. iPhone 7 and later record video as HEVC (H.265) inside a .mov container. The converter has an MP4 ready in seconds that keeps the original HEVC video, with no quality loss; it plays on iPhone, iPad, Mac and most Windows 10 and 11 PCs. If it needs to play everywhere, older PCs and TVs included, choose Convert to H.264, which takes longer.

How long does conversion take?

If your source already contains H.264 (older iPhones, most QuickTime recordings), conversion is a fast remux — usually under a second. HEVC is just as fast if you keep it as HEVC. Converting to H.264 re-encodes every frame and is much slower: on a recent Mac, a minute of 1080p HEVC takes about 4 minutes. 4K footage and older computers take longer.

Does my video get uploaded to your server?

No. Conversion runs entirely in your browser. Disconnect from Wi-Fi after the page loads to verify — the converter keeps working.

Is there a watermark or file-size limit?

Neither. Plain .mp4 output. No backend means no caps — the only limit is your device's available memory.

Will I lose quality?

If the source is H.264, or HEVC you choose to keep as HEVC, we remux (copy the video stream into MP4 without re-encoding) — 100% lossless. When we convert to H.264, we use CRF 18 by default, which is visually lossless for nearly all viewers.

Turn off your Wi-Fi. It still works.

That's how you know nothing leaves your computer.

CloudConvert, Zamzar, FreeConvert, VEED — they all send your video to a server. We don't. Conversion runs on your CPU, in your browser, via the same ffmpeg engine VLC and YouTube use.
