Music and video. They go together like peanut butter and jelly or toast and jam, and for most of us, there’s nothing more reminiscent of our youth than music and video. This may not be MTV, but you can still make an impact with the right choice of background music in your video. 

With the growth of video marketing, it’s becoming tougher to stand out from the competition. The right music track can not only elevate your videos but make them more entertaining and engaging for audiences. And, it’s a lot easier than you might think.

You may be asking yourself how do I add music or mp3s to a video online? Where can I find the right music? Well, we’ve got the answers to your questions and we show you how to add audio in WeVideo’s video editor.

How do I add audio to my video for free?

With WeVideo, you have the option of uploading music directly from your device (mobile phone, tablet, etc.), a social media channel or simply using audio from WeVideo's stock media library.

From our library of royalty-free music to your own mp3 uploads, there are countless ways (and websites) to help you add music to your video for free. These sites offer professionally designed, studio-quality audio created for use in your videos and some even have paid subscriptions for access to more audio.

1. WeVideo's stock media library

When you sign up for a free WeVideo plan, you get access to a library of audio that includes music and sound effects. These are curated and professionally designed to enhance your video. Upgrading to our Professional or Business plans will give you access to an even larger library of royalty-free stock footage.

2. Add music from a paid site

You can upgrade your WeVideo plan to access a royalty-free library of more than 1 million videos, images, and audio clips, but if you rather go elsewhere, there are countless websites to help you find the right music choice for your video. With options like SoundCloud, Premium Beat and many others, you can find and download royalty-free music to use for your video.

3. Add music from your device

One of the easiest, and quickest, ways to find and add music to your video would be through your own device. If you’re editing a video on your phone or tablet, you can upload music from the library of the device. The same goes if you’re on your laptop/desktop. It’s easy and I’ll go over how to do it further below. 

Where can I find music for my video?

You can find music relatively anywhere. From free services like WeVideo’s stock audio library and the YouTube Studio library to paid services like Artlist and Epidemic Sound, you can find commercially licensed music anywhere.

Paid options, which there are plenty of, usually take care of the licensing and usage of the audio in your video. These tracks are curated and have specific content they can be used for. Usually, these tracks are licensed for use in commercials, social ads and other marketing collateral. Just be aware, if you use audio incorrectly or in a way that breaks your subscription agreement, you could face some penalty.
