YouTube makes it easy for you to upload and share your videos, but it doesn’t give you many editing options beyond that. If you want to add or replace your video’s audio track, for example, you aren’t able to make any edits whatsoever before your video is uploaded.

In this article, I’m going to show you a quick and simple way to add or change a video’s audio track using Kapwing – it's free, requires no downloads, and gives you high-powered editing tools. Here's what you should know:

  1. Find Your Video & Audio
  2. Upload Your Video to Kapwing
  3. Add or Replace Your Audio
  4. Publish & Upload to YouTube!

Step 1: Find Your Video & Audio

Before you begin, you’re going to need to know how to find the video you want to upload to YouTube and the audio you’d like to add to it. If you’re using video or audio from somewhere online, like YouTube, Facebook, Instagram, or SoundCloud, simply go to the page with the video or music that you want. You’ll need to copy the URL of both your video and music, so it’s easiest to keep the pages open in separate tabs.

If you’re using a video or song that you have recorded yourself, or that you have saved on your device, just make sure you can find it in your file browser!

Step 2: Upload Your Video to Kapwing

Uploading your video to Kapwing is just as easy! First, go to and click “Get Started.” This will take you to the Kapwing Studio, where you can use all of Kapwing’s photo and video editing tools in one convenient place.

To upload a video from your computer, phone, or tablet, you can select the button that says “Click to upload” and find the file you want to edit in your file browser.

And if you want to upload a video you found online, click on the field that says “Paste an image or video URL.” Now, go to the video you want to upload, right-click on its URL, and select “Copy.” Back in the Kapwing Studio, right click (or just tap one more time if you're editing on your phone or tablet) on the URL field and select “Paste.” Kapwing will work its magic and upload your video to the Studio.

Step 3: Add or Replace Your Audio

Now that you’re in the Kapwing Studio, it’s simple to add your music! Start by deselecting all layers, and then selecting “Audio” from the bottom toolbar. In the Add Audio window, you can either paste the link that you copied from an online audio source like YouTube or Soundcloud, or upload an audio file from your computer.

Kapwing will automatically upload your music to the Studio. In this window, you can adjust when your music starts, trim it, and adjust its volume! Just click Add Audio when you’ve finished your edits. If you open the Timeline editor, you can also drag and drop multiple audio files directly onto the timeline, and edit or balance all of them.

Step 4: Publish & Upload to YouTube!

Once you’ve edited your video and music to perfection, click “Publish” in the upper right-hand corner of the Studio! Kapwing will begin processing your video, which may take a couple minutes for longer files. Once your video is done processing, click “Download” from the right side of the screen.

Now, head over to YouTube. Once you’ve signed into your account, click the upload button in the upper right-hand corner (it looks like a little camera with a plus-sign on it) and select “upload video.” From here, just click the upload arrow to find your video in your computer’s file browser, or drag & drop the completed video from your browser’s downloads!
