Replace video sound — no editing required

Swap out a voice track or change background music without complex audio editing. Kapwing's Replace Audio lets you upload any video and instantly split it into three clean layers: video, background sound, and vocals.

Delete what you don't need, drop in new audio—whether it's studio voiceover, royalty-free music, or AI-generated narration—and you're done.

Speed up repurposing and updating content with quick audio replacement. Fix poor sound quality, replace copyrighted music, or update older product demos and company videos without re-recording.

By the far the most user friendly software to use.

As a housewife at home looking to start a YouTube channel for fun with absolutely zero editing experience, it was so easy for me to teach myself via their YouTube channel. It takes the tediousness out of editing and encourages creativity. As long as Kapwing is around, I will be using their software.

Kapwing is my secret weapon!

Kapwing is king.

Love this site.

As an English Foreign Language Teacher, this site helps me to quickly subtitle interesting videos that I can use in class. The students love the videos, and the subtitles really help them to learn new vocabulary as well as better understand and follow the video.

Excellent subtitling features

[It] works perfectly for me. Have been using Kapwing for a year or so, and their automatic subtitle tool gets better and better every week, it's rare that I have to correct a word. Keep up the good work!

Best online video service ever. And a miracle for deaf people.

[Subtitler] is able to autogenerate subtitles for video in almost any language. I'm deaf (or almost deaf, to be correct) and thanks to Kapwing I'm now able understand and react on videos from my friends :)

This tool should be in every social media account managers' bookmark list.

Frequently Asked Questions

We have answers to the most common questions that our users ask.

Is the Replace Audio tool free?

Yes, Kapwing's Replace Audio tool is free for all users. For access to the full range of video editing tools, including AI-powered tools, upgrade to a Pro account.

Is there a watermark on exports?

If you use Kapwing on a Free account, then all exports — including Replace Audio — contain a watermark. Once you upgrade to a Pro account, the watermark is completely removed from your creations.

How to change the audio on a video

If you’re wondering how to replace audio in a video with Kapwing, it only takes a few clicks. Upload your video, split or remove the existing audio track, then add your new sound, including voiceover, music, or AI narration.

Kapwing’s audio replacer makes it easy to change audio in video, adjust timing, and export without worrying about sync issues. No editing experience required.

Can I replace audio in a YouTube video?

Yes, many creators use Kapwing to fix or update their own YouTube content. Upload the original video file or paste the YouTube link to upload your video into the studio. Then remove the old track and upload your new audio.

This is a common solution for copyright claims, improved narration, or translating content. Once you replace sound in video, you can download the updated file and re-upload it to YouTube.

Can I remove and replace only part of the audio?

Yes, to remove and replace audio from video selectively, start by splitting your audio from the video file. Use the "Split Layer" tool to cut your audio track at the beginning and end of the section you want to replace. Then delete that section and replace it with a new track.

This makes it easy to replace video sound only where needed, like swapping background music while keeping dialogue, or fixing one section without redoing the whole video.

What file types does Kapwing support?

Kapwing supports most popular file types, including MOV, MP4 and WebM for video and MP3 for audio. Download videos in any format with adjustable resolution and compression setings.
