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 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 :)

Frequently Asked Questions

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

How to duplicate audio with Kapwing

To duplicate song or audio files with Kapwing, start by creating a new project in the studio. Click to upload your audio file. Then click the arrow next to the file name in the top toolbar. Select "Make copy" and give your duplicated video file a name and folder location. Click "Copy" to create your duplicate audio file.

From here, you can use any of Kapwing's extensive audio editing tools to adjust your audio duplications or drop them into video projects. When you're ready, click "Export project" at the top right to create a downloadable audio file.

What file formats can I duplicate?

Kapwing uses the MP3 format for audio-only files. You can also upload videos with integrated sound and detach the audio for duplication, replacement, or deletion.

How to duplicate audio files on iPhone or tablet

If you want to duplicate audio using your phone or tablet, including Apple and Android devices, open the Kapwing studio in your mobile browser. Click to upload your audio, then return to the Kapwing homepage. Find your new project and click the three dots next to the file name. Click "Duplicate" to make a copy of your audio file. From there, you can edit or export your audio as usual.

Can I duplicate audio after editing it?

Yes, you can duplicate audio files at any point, including after editing them. To preserve a master copy of your audio, make a copy before you start editing. To duplicate an already edited audio file, make your edits first, then duplicate the file for final edits or export.

What's the difference between duplicating and exporting audio?

When you duplicate audio in Kapwing, you create a new project file without re-rendering or compressing the original. This means your audio duplicate keeps the same quality and can be edited independently.

Exporting, on the other hand, creates a final downloadable file. Audio duplication is ideal for version control, experimentation, and non-destructive editing before final export.

Can I duplicate audio from a video file?

Yes. Kapwing supports audio video duplication by allowing you to upload a video, detach the audio, and create a copy of the sound track.

This is useful for repurposing podcast videos, interviews, webinars, or social clips where you need to duplicate audio separately for editing, remixing, or distribution.

Is there any quality loss when I duplicate audio?

No. Kapwing creates a direct audio duplicate without compressing or altering the original file. You can duplicate audio songs, voice recordings, or extracted tracks with no quality loss inside your project.

Quality settings only apply when you export the final file, not during the duplication process.

Can teams use Kapwing for audio duplication and editing workflows?

Yes. Kapwing’s shared workspaces make it easy for teams to duplicate audio, organize versions, and collaborate in real time.

Instead of sending files back and forth, teams can manage audio duplication and editing in one online project hub, speeding up review and publishing workflows.

Can I duplicate audio tracks within the same project?

Yes, you can upload an audio track, then copy and paste it in the timeline to create a duplicate version within the same project. This allows you to edit and remix tracks without leaving your browser.
