Convert MOV to MP4

Convert MOV to MP4 or MP4 to MOV instantly — private, offline, right in your browser.

iPhone videos arrive on your computer as .MOV files, and plenty of Windows apps, upload forms and editors refuse to open them. This MOV to MP4 converter turns them into MP4 files that play everywhere, right in Chrome, without uploading anything. 🚀 Quick Start 1. Click the extension icon. The converter opens in its own tab. 2. Drop one video or a whole set of them. 3. The finished MP4 is saved to your computer. ⚡ MOV to MP4 in Seconds Most phone clips already hold the same video data an MP4 uses, so the extension only swaps the outer container. A one-minute clip is ready in about a second, with zero quality loss and no re-encoding. 📱 iPhone HEVC Videos That Won't Play on Windows Newer iPhones record in HEVC (High Efficiency). Windows often can't play it without a paid codec, so even a renamed file stays black. For these clips the extension re-encodes the video to H.264 on your own computer. The result plays in the standard Windows player, in browsers, in chat apps and in editors. This takes longer than a container swap, and before it starts you see an honest estimate for your file. On computers without a hardware decoder it runs in software and can take a few minutes. 📂 Batch Conversion Select several files at once and they convert one after another while you keep working. Large batches can be written straight into a folder you choose. 🔄 MP4 to MOV Too Need a .MOV for Final Cut Pro or iMovie? Drop an MP4 file and get a MOV back, with the same speed and the same privacy. 💾 Big Files Long recordings and camera exports are fine. For large videos the extension asks where to save the result and writes it straight to disk, so the size of your file doesn't depend on browser memory. 👥 Who It Helps iPhone owners who send clips to a Windows PC. People whose upload form, school portal or video editor only accepts MP4. Editors who move footage between Mac and Windows tools. Anyone who has renamed a file to .mp4 and found it still won't play. 💡 Tips for Smooth Results • Not sure what kind of file you have? Just drop it in. The converter checks the codec itself and tells you upfront whether it is a quick swap or a re-encode. • Converting a whole trip? Select all the clips together. Each MOV to MP4 result keeps the original file name, only the extension changes. • Your original file is never touched. The converter always writes a new file. • If a video still won't play after conversion, tell us through the feedback link in the converter. Every report gets read. 🔒 Privacy The video never leaves your computer. There is no upload, no server queue and no account. We collect anonymous usage statistics, such as which conversion path was used, with no file names and no personal data. ❓ FAQ 🔷 Does converting MOV to MP4 reduce quality? 💡 Not for most phone clips: the video data is copied as is.
