How to Convert MOV to MP4

.MOV is Apple’s video container format. It’s what iPhone screen recordings, QuickTime exports, and Mac-edited videos save as by default. It works perfectly on Apple devices. On other platforms — Windows, Android, some web upload forms — MOV either won’t play or causes problems.

The fix: convert to MP4. The video content is usually identical (both formats commonly contain H.264-encoded video with AAC audio); only the container changes. So conversion is fast and lossless.

The fastest path: change the file extension (often works)

This is the dirty trick that surprisingly often works:

1. Find the .mov file in Finder (Mac) or Explorer (Windows)
2. Rename the extension from .mov to .mp4
3. Try playing it

Why this works: most .mov files contain H.264 video + AAC audio, which is exactly the same content commonly stored in .mp4 files. The two formats are containers; the actual video and audio data inside is often byte-identical.

When this doesn’t work: .mov files using older or specialized codecs (Apple ProRes, Animation, MJPEG) need real conversion. The rename shows as a .mp4 but most players still won’t play it.

For typical iPhone or QuickTime-exported MOVs, the rename trick works. If you’re feeling cautious, do a real conversion instead.

Real conversion with HandBrake (desktop, free)

HandBrake is the gold-standard free video tool. It properly converts MOV to MP4 with format and codec control.

1. Install HandBrake (Windows, Mac, or Linux)
2. Open HandBrake, drag in your .mov file
3. Choose a preset:
   • Fast 1080p30 for general use
   • Web → Gmail Large 3 Minutes 720p30 for email-friendly
   • Apple → iPhone 6/7/8 for iPhone playback
4. Set output filename ending in .mp4
5. Click Start Encode

Encoding speed depends on your computer and video length. A 2-minute clip typically takes 30-90 seconds to convert.

Conversion with VLC (free, simpler)

VLC also converts video, with a simpler interface:

1. Open VLC
2. Media → Convert / Save
3. Add your MOV file
4. Click Convert/Save
5. Choose Profile: H.264 + MP3 (MP4)
6. Pick output filename ending in .mp4
7. Click Start

Slower than HandBrake but easier UI.

On iPhone (in-app conversion)

iPhone screen recordings save as .mov. To convert to .mp4:

Use the share sheet trick:

1. Open the video in Photos
2. Tap Share → Save to Files (or similar)
3. The exported file is .mov though
4. Some third-party apps convert post-export

Better: use a free converter app:

• “Video Converter” by various developers (free with ads, paid for no ads)
• “Media Converter” — similar approach
• Drag in video, choose MP4 output, export

For occasional conversion, paid pro apps (Adobe Premiere Rush) handle export to MP4 cleanly.

On Android

Most Android phones natively support .mov playback. But for sharing to platforms that don’t accept MOV:

Use a converter app:

• “Video Converter” (free, ad-supported)
• “Format Factory” mobile

Or compress + convert simultaneously (often the same thing on mobile):

• Open the MOV in any video editor (CapCut is free)
• Export with MP4 chosen as format
• The export is your converted file

Browser-based limitations

We don’t have a browser-based MOV to MP4 converter because (as covered in our Video Compression guide) browser-based video conversion struggles with the computational load.

The good news: the rename trick handles most MOV-to-MP4 needs in one second. The few cases where you truly need re-encoding are well served by HandBrake.

When the audio matters more than the video

Sometimes you have a MOV and only care about the audio (a recording, a podcast you took as video, an interview):

• MOV to MP3 extracts the audio as MP3
• 10× smaller than the original video
• Plays everywhere

If your goal was “MOV won’t open on my Windows PC and I just want to hear the conversation,” extracting audio is faster than full video conversion.

What about .mov from professional video work?

Apple’s professional video codecs (ProRes, Animation, ProRes RAW) produce .mov files much larger than typical iPhone/QuickTime exports. These contain less-compressed video data for editing flexibility.

Converting ProRes MOV to MP4 with H.264 encoding usually shrinks the file 5-20×. The visual quality stays similar for most playback. The “edibility” decreases — H.264 is harder to color-grade and edit cleanly.

So for editing work: keep the original ProRes MOV. For sharing/distribution: convert to MP4 with H.264.

When the conversion fails

A few reasons conversion might not work cleanly:

Damaged or corrupted source: the MOV may have problems that no conversion tool fixes. Try playing in VLC first — if VLC can’t play it, conversion won’t help.

Encrypted DRM video: paid video downloads (iTunes movies, Netflix downloads) are encrypted. No legitimate tool decrypts them.

Very old MOV variants: from QuickTime 2/3 era (mid-1990s) using Animation, RPZA, Cinepak codecs. HandBrake handles these but the result may look poor due to source quality limits.

Mixed-stream files: MOVs with multiple video tracks, alternate audio, subtitles. The conversion may pick one stream; you may need explicit settings to capture everything.

For typical iPhone, screen recording, or modern QuickTime MOV files: conversion works cleanly with no manual intervention needed.

After conversion

Compress further if needed: our Compress Video guide covers options.

Extract audio if applicable: MP4 to MP3 gives you the audio track separately.

Edit the timing: Audio Trimmer crops the audio if just trimming is needed; for video editing, use CapCut, DaVinci Resolve (free), or iMovie.

Why MP4 dominates

A short tour: the MPEG group standardized MP4 in 2003. By the late 2000s it was the default for digital video distribution. By 2015, every major platform (YouTube, Vimeo, Netflix’s delivery codec inside DRM, broadcast TV, blu-ray) had standardized around H.264 + AAC in an MP4 container.

The MOV format predates MP4 by a decade (Apple introduced QuickTime in 1991). MP4 actually adopted MOV’s structure as a starting point — they’re technically related formats. But MOV stayed Apple-specific in branding while MP4 became the universal version.

Today, virtually every device and platform reads MP4. MOV reads on Apple devices natively and elsewhere with varying success.

TL;DR

• MOV often = MP4 with different file extension — try renaming .mov to .mp4 first
• Real conversion needed: HandBrake or VLC on desktop
• iPhone/Android: free converter apps
• Audio only: MOV to MP3
• No browser-based tool — video conversion is too computationally heavy
• Conversion is usually lossless when both formats use H.264 + AAC (the common case)
• MP4 works everywhere; MOV is Apple-centric
