Add Music to a Video
To add music to a video, upload the video and your audio file, then choose how they combine: replace the original sound entirely, or mix the music underneath it. The tool renders one finished file with the soundtrack built in — no timeline editing involved.
Music carries a video: raw footage with ambient noise feels unfinished, while the same clip under the right track feels produced. The replace-or-mix choice matters — replace suits montages and silent footage, while mix keeps voices audible with the music sitting behind them.

- 2
Choose replace or mix
Pick replace to swap the original audio out for the music entirely, or mix to blend the track with the existing sound, keeping dialogue or ambience audible.

Full soundtrack swap for montages, or a blended mix that keeps original voices over the music.
Your music, your license
You upload the track yourself, so you control exactly what plays and what rights you have to it.
No timeline editing
Two uploads and one choice replace what would otherwise be an audio-syncing session in an editor.
Clean unbranded export
The finished video downloads without any watermark — nothing between your work and your audience.
Frequently asked questions
Should I replace the original audio or mix the music in?›
Replace when the original sound adds nothing — montages, timelapses, muted footage. Mix when the video contains speech or ambience worth keeping: the music plays alongside the existing track. If dialogue fights the music in a mix, try a quieter or sparser track.
What audio can I legally add to my video?›
Use music you created, purchased with a license, or obtained from a royalty-free library that permits video use. Adding commercial songs you do not have rights to can get posts muted or removed by platforms. The tool accepts your file either way — the rights are your responsibility.
How many credits does adding music cost?›
Adding music costs 2 credits per job, since it processes both a video and an audio file. The 3 free credits from signup cover your first soundtrack. For more, one-time credit packs are on the pricing page — no subscription required.
What if the music is longer or shorter than my video?›
The output follows your video. If the track runs longer, it is cut when the video ends; if it is shorter, the remainder of the video continues without it. For a tight fit, trim either the video or the audio to matching lengths before combining them.
