MOV is common in the Apple world, especially for iPhone videos, QuickTime exports, and screen recordings. The problem appears when that file has to play on Windows, Android, a smart TV, a browser upload form, or software that expects MP4. Converting to MP4 usually solves the compatibility issue because H.264 video with AAC audio is accepted almost everywhere.

This converter processes MOV files in the browser with FFmpeg WebAssembly. It is useful for iPhone HEVC footage, QuickTime screen recordings, client clips, and older MOV files that need a more portable container. You can keep the original resolution, downscale for sharing, choose a quality preset, and trim unwanted sections during the same conversion.

For best results, use High quality when the video will be edited again, Medium for everyday sharing, and Low only when a smaller file is the main goal. Large 4K HEVC videos can be CPU-heavy, so desktop browsers are more reliable than phones for long files. If playback is the only issue and the codecs are already compatible, the conversion may be fast; if the video must be re-encoded, it will take longer but create a more broadly compatible MP4.

Why Use Our MOV to MP4 Converter

Universal Compatibility

MP4 is the one format that works on every device you own —iPhones, Android phones, Windows PCs, Macs, Linux, smart TVs, gaming consoles, tablets, and every web browser. Converting MOV to MP4 eliminates playback issues once and for all.

100% Private & Secure

Unlike most online converters that upload your files to a server, our tool runs WebAssembly entirely in your browser. Your videos never leave your device —not to a cloud server, not to a third-party service, not anywhere.

No Software Installation

You don't need to download or install anything. No QuickTime Player, no VLC, no HandBrake, no desktop converter apps. Just open this page, drop your file, and convert. It works on any modern browser.

Full Quality Control

Choose between three quality presets: High (CRF 18) for near-lossless quality at larger file sizes, Medium (CRF 23) for a great balance of quality and size, or Low (CRF 28) for the smallest possible file.

Resize & Trim in One Step

Need to make your video smaller for easier sharing? Scale it down to 1080p, 720p, 480p, or 360p right during conversion. You can also trim out unwanted sections by setting start and end timecodes.

iPhone HEVC/H.265 Support

Modern iPhones record video in HEVC (H.265) inside MOV containers. Our converter handles these files natively —your 4K iPhone videos convert just as easily as any other MOV file.

Features

  • Convert MOV (QuickTime) to MP4 with H.264 video and AAC audio encoding for maximum compatibility across all devices
  • Adjustable output resolution —keep the original, or scale down to 1080p, 720p, 480p, or 360p for smaller files
  • Three quality presets: Low (smallest file, CRF 28), Medium (recommended balance, CRF 23), High (near-lossless, CRF 18)
  • Optional time range trimming —extract exactly the portion of the video you need by setting start and end times
  • Supports all MOV codecs including H.264, H.265/HEVC, ProRes, MPEG-4, and Motion JPEG —no MOV file is too obscure
  • 100% local processing via WebAssembly —your video never leaves your device, ensuring complete privacy and security

Frequently Asked Questions

Does converting MOV to MP4 lose quality?

At the Medium (CRF 23) or High (CRF 18) quality setting, the quality difference is imperceptible to the human eye. CRF 18 provides near-lossless quality with a larger file size, while CRF 23 strikes the perfect balance between quality and file size. For the smallest possible file, choose Low (CRF 28).

Can I convert iPhone-recorded MOV files?

Absolutely. IPhone videos, including those recorded in HEVC/H.265 format, are fully supported. The converter handles HEVC within your browser, so 4K iPhone footage can be converted without installing a separate app.

Will the file size change after converting MOV to MP4?

It depends on your quality and resolution settings. At Medium quality with the original resolution, the MP4 file is typically 30—0% smaller than the original MOV. If you also scale down the resolution (e.g., from 4K to 1080p), the size reduction is even more significant.

Is this MOV to MP4 converter really free?

Yes —completely free. There are no hidden costs, no premium tiers, no daily limits, and no watermarks on your output. You can convert as many MOV files as you want, as often as you want.

Do my files get uploaded to a server?

No. Everything happens right in your browser using WebAssembly technology. Your MOV file is read locally, processed locally, and the resulting MP4 is saved locally. At no point does any file data leave your device.

What's the maximum MOV file size I can convert?

There is no hard server-side limit because there is no server. The only limit is your device's available RAM —typically 2— GB on most computers and phones. For best performance with very large files (2 GB+), we recommend using a desktop browser.

Does this tool work on mobile phones?

Yes, it works on both iOS Safari (16.4+) and Android Chrome. You can convert MOV files directly on your phone without installing any app. The interface adapts to smaller screens for easy touch-based operation.

Can I convert multiple MOV files at once?

The tool processes files one at a time in your browser. After each conversion completes, you can click the Reset button and immediately start the next file. There is no queue, no waiting, and no limit on how many files you can convert.
