Will the MOV quality be preserved in the MP4?

H.264 at CRF 23 (our default) produces excellent visual quality for most content — indistinguishable from the source at normal viewing distances. Screen recordings, phone videos, and standard camera footage all look great. For professional video production, you'd typically use a dedicated tool like Handbrake with finer controls.

Why are MOV files incompatible on non-Apple devices?

MOV is Apple's QuickTime container format. While VLC and modern browsers support it, many native Windows apps, Android devices, and web players don't. The video inside a MOV is often H.264 or HEVC (which MP4 also uses), so conversion is usually fast because only the container needs re-muxing — not the video stream. However, some MOV files use ProRes or Apple-only codecs that require full re-encoding.

How large can my MOV file be?

Up to 500 MB. Files over 200 MB will show a processing time warning. On a modern laptop, a 100 MB MOV typically takes 1–3 minutes. Processing happens in a Web Worker so your browser stays fully responsive.

Does the MP4 keep the original audio track?

Yes. The audio is re-encoded to AAC at 128 kbps, which is transparent quality for typical speech, music, and ambient audio from phone or camera recordings. The audio and video are kept in sync.

Can I convert iPhone screen recordings or FaceTime videos?

Yes. iPhone screen recordings are saved as MOV (HEVC codec). Our converter handles HEVC-in-MOV and re-encodes it to H.264 in MP4. FaceTime recordings are similarly supported. Note that HEVC decoding is more CPU-intensive than H.264, so these conversions take a bit longer.

Convert MOV to MP4 — Universal Compatibility

MOV files from iPhones, Mac screen recordings, and cameras work everywhere on Apple devices but often fail on Windows, Android, and web players. This tool re-encodes MOV to H.264 MP4 — the most universally compatible video format — entirely in your browser. No upload, no account, no cloud service.

How to use this tool

Upload your MOV file
Drop a QuickTime MOV file onto the converter. Files from iPhones, Mac screen recordings, and professional cameras are all supported. Up to 500 MB.
Wait for FFmpeg to load
On first use, the FFmpeg WebAssembly module downloads in the background (~30 MB). This is cached after the first time, so subsequent conversions start immediately.
Click Convert
FFmpeg re-encodes the video using H.264 (libx264) with CRF 23 — a good balance of quality and file size — and AAC audio at 128 kbps. Progress is shown in real time.
Download the MP4
The output MP4 is compatible with all platforms: Windows Media Player, VLC, Chrome, Safari, Android, and every modern smart TV. Download and use anywhere.
