Table of Contents

There are a number of media converters that let you convert one format into another using both desktop tools, and online-based converters. Let’s find out how to turn MOV into MP4, learn their differences and what converter to choose depending on your task.

MOV is a media standard for Mac computers, while MP4 is a universal video standard, widely used on the web. You can easily convert MOV video to MP4 using this online service or an offline tool, such as iMovie or Compressor, which is a paid application made by Apple used for professionals.

Benefits MOV vs MP4

Both formats are media containers and they are used for playing video files locally on devices, such as Apple computers, phones, tablets, and over the network. Let’s compare the benefits and where each format can be better used.

About MOV

MOV is a QuickTime standard for playing back media on Apple devices, such as Mac computers, iPhones, iPads, Apple TV, and other devices. It’s supported by an operating system by default. For example, macOS, iOS, and tvOS, have built-in MOV support, and there’s no need to install any codecs or third-party tools to play videos.

MOV files can store audio and video tracks, as well as subtitles and other metadata. Files with a .mov extension use QuickTime File Format (QTFF). Apple engineers created MOV in 1999.

MOV pros

Apple tools can quickly recompress MOV files for different sizes to be played on different devices. For example, if you have a 4K video downloaded and you’d like to watch it on your phone during the flight with no Internet connection, you can use a tool (e.g., iMovie) to quickly export it to the size you need.

About MP4

MP4, or an MPEG4 is a universal video container format, widely used on the web. It may contain video streams and audio streams and supports many codecs for either media type. In fact, it can contain a mov file inside without decoding.

The first MP4 specification was created in 2001. It’s based on an Apple QuickTime architecture and MPEG-4 Part 12, or MP4. While MOV is limited in terms of codecs to its own proprietary one, MP4 supports a variety of codecs for video streams, such as H.264 or AVC.

MP4 pros

MP4 is more modern than MOV and much more versatile. Not only Apple devices, but all hardware and software players can play MP4 files. It’s way better supported on the web because its whole purpose was streaming on the Internet.

Resolution can be set to one of the following values:

  • Same as your source video

  • HD 1080p 1920x1080

  • H.265 / HEVC

Audio codecs support in MP4 in this online converter are:

  • AAC (Advanced Audio Codec)

  • MP3

Last but not least output option is the compression ratio. The actual option’s name is “Approximate output file size”.

By dragging this slider, you can set the quality of the video. The more you increase it, the better quality will be and the output file size, consequently.
