Free MOV to MP4 Converter Online

A free MOV to MP4 converter: turn MOV clips — including iPhone videos — into MP4s that play everywhere.

Free tool · No sign-up · Private

Drop in a MOV file

MOV files up to ~50MB — including iPhone videos. Converted 100% in your browser with ffmpeg — your file never leaves this device. First run loads the video engine (~30 MB), once.

Private by design. Conversion runs 100% in your browser with ffmpeg.wasm. Your MOV is never uploaded, stored, or seen by anyone.

Formats & limits

What you can convert

Straightforward limits, stated plainly.

MOV in, MP4 out

This page converts MOV (.mov) files only — Apple's container, and the format iPhone cameras, QuickTime, and many screen recorders save in. Output is always a standard .mp4 that plays everywhere.

Remux first, re-encode if needed

The tool tries `-c copy` remuxing first: instant, lossless, same file size. iPhone HEVC clips and MOVs with unusual codecs take the re-encode path to H.264 + AAC — slower, but playable on far more devices. The result reports which path was taken.

~50 MB file cap

iPhone video adds up fast — a minute of 4K can be 400 MB — and the engine runs in browser memory, so files are capped at about 50 MB. Trim longer clips before converting.

Private by design

The ffmpeg engine (~30 MB) downloads once per visit, then conversions are local. No accounts, no uploads, no watermarks — your clips never leave your device.

How it works

Three steps to your MP4

Drop in a MOV file

Choose a .mov file up to ~50MB — an iPhone clip, a screen recording, anything. It stays on your device; nothing is uploaded.

Convert to MP4

Press “Convert to MP4”. The tool tries an instant lossless remux first, and re-encodes to H.264 + AAC only when your MOV needs it (like iPhone HEVC clips).

Preview and download

Watch the MP4 right on the page, see whether it was remuxed or re-encoded, then download it. It plays on every phone, TV, and computer.

Use cases

When conversion helps

From Apple-only to plays-anywhere.

iPhone videos for everyone

An iPhone MOV — especially HEVC — won't play on some Windows PCs, Android phones, and smart TVs. Convert to MP4 and the clip opens for grandparents, clients, and colleagues alike.

Upload to social and YouTube

Social apps and upload forms prefer MP4. Convert your MOV screen recording or camera clip here and the upload goes through without a “format not supported” surprise.

Windows-friendly clips

Editing on a Windows machine? Some Windows editors and players handle MOV badly. An H.264 MP4 drops into any timeline — Premiere, DaVinci, CapCut — without transcoding headaches.

Smaller files to share

A re-encoded H.264 MP4 is typically much smaller than the original MOV, especially for HEVC iPhone footage. Same clip, easier to attach, message, or back up.

FAQ

MOV converter questions

Why won't my MOV play on Windows or Android?

MOV is Apple's container, and some Windows apps and Android players handle it badly — especially iPhone clips recorded in HEVC. MP4 with H.264 + AAC is the one combination every device on earth plays, which is exactly what this tool produces.

Will I lose quality converting MOV to MP4?

Usually not at all. The tool first tries a lossless remux — repackaging your existing streams into an MP4 without touching the data. iPhone HEVC clips and MOVs with unusual codecs get re-encoded to H.264 + AAC at high quality (CRF 23), and the result tells you which path was taken.

My iPhone video was recorded in HEVC. Will it work?

Yes. HEVC (H.265) doesn't fit every MP4 use case, so HEVC clips take the re-encode path to H.264 + AAC — which plays on far more devices, including older phones, TVs, and browsers. It takes longer than a remux, but the result is the most compatible file possible.

How big can my MOV file be?

Up to about 50 MB. iPhone clips add up fast — a minute of 4K can be 400 MB — so trim or transfer shorter clips for browser conversion. The engine runs entirely in your browser's memory.

Is my video uploaded anywhere?

No. The ffmpeg video engine (~30 MB) loads once into your tab, and your MOV is converted locally. Your video never leaves your device — no server, no account, no watermark.
