Add Music to a TikTok Video
To add music to a TikTok video before uploading, add your clip and your audio track below, choose whether the music replaces the original sound or mixes with it, and download the combined file. It runs in the browser and the output carries no watermark.
This is for audio you own — your own beats, licensed tracks, voiceovers, or a brand sound — baked permanently into the file. For trending sounds, use the TikTok in-app library, since licensed trends only count when added there; the two approaches complement each other rather than compete.
How to add music to TikTok video
- 1
Upload video and audio
Add your video (up to 500 MB) and the audio file you want on it — an MP3 export of your track, a recorded voiceover, or any sound you have the rights to use.
- 2
Choose replace or mix
Replace swaps out the original audio entirely — ideal over raw footage. Mix layers the music under the existing sound, so speech or ambient audio stays audible.
- 3
Download and post to TikTok
Save the combined video and upload it through the TikTok app. The music is part of the file, so it plays exactly as you mixed it.
Why use Video-Matic
Your sound, your control
The audio is baked into the file at the level you chose — TikTok cannot swap, trim, or rebalance it.
Replace or layer
Kill wind noise entirely with Replace, or keep your voice on top of a music bed with Mix.
One file, every platform
The finished clip works as-is on Reels, Shorts, and anywhere else — no per-app audio editing.
No watermark added
The output is clean, so your post looks native rather than exported from a tool.
Frequently asked questions
Should I add music here or in the TikTok app?›
Both have their place. Use the TikTok library for trending licensed sounds — participating in a trend only registers when the sound is added in-app. Use this tool for audio TikTok does not offer: your own music, voiceovers recorded elsewhere, or a soundtrack that must stay glued to specific moments in the edit.
Can I keep the original sound and add music on top?›
Yes — choose Mix and the uploaded track is layered with the existing audio, so dialogue or ambient sound remains audible under the music. Choose Replace when the original audio is noise you want gone completely.
What audio formats can I upload?›
Common audio files like MP3 work directly — export your track from any editor or recorder and upload it alongside the video. Keep each file under the 500 MB limit, which is far more than any music track needs.
How much does adding music cost?›
Adding music costs 2 credits because the job processes two files. Signup includes 3 free credits, covering your first video. After that, one-time credit packs are available — no subscription. Files are deleted from EU servers within 24 hours.
