Your one-stop shop for editing audio and video tracks
Fill in the silences of your video to keep your viewers engaged. When you add background music to a video, it feels complete.
If you don’t have any songs to use as background music in mind, choose from a variety of audio tracks in Kapwing’s video editor to add to your own video. Add as many audio tracks and video files as you want!
Adjust your audio tracks by using the volume slider or the remove background noise tool to manage noise reduction. Some content creators edit their original video while they add music so they can match the beat to each transition or jump cut. Create music videos, video podcasts, record voiceovers, radio shows, and more with Kapwing’s online video editor.

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.

Love this site.
As a 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.

[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!
