MOV to MP4 converter

About

🎬 MOV to MP4 — convert mov to mp4 right in your browser, with nothing ever leaving your computer.

Got a .mov from your screen recorder, camera or phone and need a universal .mp4? This converter turns any QuickTime file into an .mp4 that plays everywhere — on Windows, Android, web players, social uploads and every editor. No video editor, no online uploader, no account, no sign-in.

🔒 100% local and private
The whole conversion runs inside your browser with WebAssembly (ffmpeg.wasm). Your file is never uploaded — there are no servers and no network requests that carry it anywhere. Everything stays on your device, so even large, sensitive or personal clips are completely safe. Nothing is logged, nothing is tracked, nothing is sent to the cloud. This is privacy you can actually verify: open your browser's Network tab while you convert mov to mp4 and you will see zero outgoing traffic with your video.

⚡ Fast by design
Most .mov files already hold MP4-friendly streams (H.264 video + AAC audio), so the converter simply swaps the container instead of re-encoding the whole clip. That finishes in seconds and keeps the original picture and sound exactly as they were. When a .mov uses a codec the output container can't carry as-is, it automatically re-encodes to H.264/AAC so you always end up with a file that plays.

✨ What you can do
➤ Convert mov to mp4 in one step — drop a file and it starts right away
➤ Turn .mov to .mp4 without losing quality on a normal H.264 clip
➤ Batch several files at once and download them all together as a single zip
➤ Keep working offline — no connection is needed once it's installed
➤ Switch the interface theme and language to suit you

🗂️ Who it's for
1. Creators who recorded on a Mac or iPhone and need a shareable .mp4
2. Anyone uploading video to sites that expect .mp4, not QuickTime
3. Windows and Android users who want a clip that opens everywhere
4. Anyone who wants a private way to change the format without a website

💡 Why MP4 instead of MOV
MP4 is the universal video container. While mov and mp4 often hold the same H.264/AAC streams inside, .mov is tied to Apple's QuickTime world, so it can refuse to open on Windows, Android and many web players. Converting mov to mp4 gives you the format that plays everywhere without changing the underlying quality, so the output looks identical to the source.

📌 Tips for the best result
🔹 For a normal H.264 clip, the step is instant and lossless.
🔹 Re-encoding only happens when it is genuinely needed for compatibility.
🔹 Big files work too — everything stays on your device, limited only by your computer's memory.
🔹 You can run several conversions back to back without reloading anything.

🆚 Why this instead of an online tool
◆ No upload, so no waiting for your video to travel to a server and back.
◆ No file-size cap imposed by a website, and no daily quota on exports.
◆ No ads, no watermark, no email, and no hidden paywall.
◆ Your private footage simply never leaves the machine it's on.
