How to convert audio files to a video on Mac

6 min read

There are over 4.5 billion internet users worldwide, and video content has a 92% audience reach among them. With this kind of statistics, it’s evident that videos are the most popular type of content shared online today.

Both long and short videos are getting millions, sometimes billions of views, and almost 15% of millennials watch up to 20 hours of online video per week. No wonder that creating and sharing videos on social media has also become a big part of almost every company’s marketing strategy.

Plus, most social media platforms don’t support direct audio files uploads, which is another reason for the need to get familiar with how to convert audio to video. Let’s master this art so you can easily convert MP3 to video and expand the scope of your online presence!

Audio to video: convert files with images and effects

While extracting audio from a video or adding a voiceover to a silent MP4 file sounds familiar to many, the idea of being able to convert audio to video with pictures may sound a bit too surreal. Yet, it's very realistic and not at all as complicated as it might sound at first.

However, it’s important to understand the difference between the two most popular media file formats before starting the conversion process. The mp4 file format is highly versatile and can handle many media types like text, images, audio and video, whereas the mp3 format can only handle audio. That’s why converting mp3 audio to mp4 video can’t be done by simply changing the file extension and requires changes on the level of content creation.

Let's start with the simplest and most effective solution, and like with most tasks, that means turning to professionals for help. A universal media converter is the quickest way to convert audio with images into a video file. Let's explore Permute, a handy conversion utility for Mac.

Permute is a highly convenient converter that can change any audio, video, or image format into any other media. All that’s needed from you is a click to begin the conversion process.

That’s it! You’ll never have to worry about file compatibility again because the format you need will always be three simple steps away!

Audio to video converters online

There are also plenty of MP3 to video converters online that perform basic conversions. All you need to do is upload your file, select the background for your video, and click to convert. Although easy to use, these online tools fall short when it comes to control and quality, lacking advanced settings and often outputting a low resolution video file.

Apart from that, there are certain privacy and security concerns associated with using some of these online services, so if you do decide to take this route, protect yourself by using ClearVPN to safeguard your network connection, and regularly check your Mac for malware and viruses using CleanMyMac X.
