Add Audio to Video Without Touching an Editor
Add audio to video in minutes — upload your clip and your audio file, and Wideo merges them for you, right in your browser. No downloads, no timelines, no editing experience required.
One Upload, Instantly Merged
Most audio and video editors want you to sync tracks manually on a timeline, dragging waveforms back and forth until the timing feels right. It’s slow, and it’s easy to get wrong. Here, the process is simpler: upload your video and your audio file, choose whether to replace the original sound entirely or mix your new track in alongside it, adjust the volume if needed, and we handle the merge automatically. No waveform editing, no manual syncing, no software to install — just a finished video with your audio in place, ready to download in a couple of minutes.

Producing Video at High Volume? Audio Shouldn’t Slow You Down
One-off audio merges are easy. The problem shows up when your team is shipping dozens of videos a week, and every one needs the right music, voiceover, or sound levels — handled the same way, every time. Wideo’s workflows plug into your existing content pipeline, so audio stays consistent no matter who’s producing it or how fast your team is moving.
We keep your audio consistent, even at full production speed.
