Everything you need to add a song, mix audio, and export a polished video – all in one free mobile app.
Built-in royalty-free music library – no copyright issues
Movavi App includes a built-in library of royalty-free background tracks organized by mood and genre. Choose a song, preview it against your footage, and drag it to the audio timeline. Every track in the built-in library is cleared for use on YouTube, Instagram, TikTok, and other platforms without copyright claims or monetization blocks. No external download required – the music is right inside the app.
Add any song from your device – MP3, M4A, or voice memos
To add music you already own to a video, import it directly from your Files app, Voice Memos, or any audio file saved to your device. Movavi App accepts MP3, M4A, AAC, and WAV audio files. Drag the imported track to the audio timeline and align it to the video. This is the correct workflow for adding a specific song you’ve purchased or downloaded from a royalty-free source to a video for YouTube or social media.
Volume, fade in/out, and speed
Once the music track is on the timeline, tap it to access audio controls: adjust the volume and speed levels to balance music against any original video audio, set a fade in at the start and fade out at the end for smooth transitions. These controls give your video a professional, broadcast-quality audio mix.
Combine a separate audio file with any video clip
To merge a standalone audio file with a video clip in Movavi App, import both files into the same project and place them on separate tracks in the timeline. Align the audio start point to the desired position in the video, trim both to the same length, and export. This is the standard workflow for adding a voiceover, narration, or extracted audio track from one video over a different video clip.
Three reasons creators choose Movavi App for adding music to their videos.
From a camera roll clip to a music-backed exported video in four taps.
Download Movavi App from the App Store. Open the app and tap the + icon to create a new project. Select the video clip you want to add music to from your camera roll. The clip loads onto the Movavi App timeline.
Tap the Music icon in the editing toolbar at the bottom of the screen. This opens the music library with tracks organized by mood and genre. Tap any track to preview it. To use your own audio file instead, tap the Add from files button and select an audio file.
Tap the track you want to add and it appears on the audio track below your video clip. Trim the audio by dragging its edges to match the video length. Tap the track to open audio settings: adjust speed and volume to balance music against the original video audio, and enable fade in and fade out for smooth transitions.
Tap the Play button to preview the video with the music. When it sounds right, tap the Export button in the top-right corner and select Save. Your video with music saves to your camera roll at full resolution. You can also tap a social media icon to post directly from Movavi App to Instagram.
Adding music to videos is one of the most universal editing tasks across every content format.

Common questions about how to add music to videos on an iPhone.
To add audio to an existing video on an iPhone using Movavi App:
Both your original video audio and the new music track can coexist on the timeline – use the volume sliders to balance them.
To merge a separate audio file with a video clip on an iPhone using Movavi App:
To extract audio from one video and place it over a different video on your iPhone:
Alternatively, if both clips are accessible in Movavi App, you can add both as tracks, mute the video track’s original audio, and use the audio-only portion of the other clip by separating it on the timeline.
Apple Clips has limited audio editing compared to a dedicated software like Movavi App. In Apple Clips, you can add a song from your Apple Music library or a built-in soundtrack during or after recording: tap the Music note icon before recording to choose a song, or after recording to select a Soundtrack. The limitation is that Apple Music subscription tracks are DRM-protected and may not export cleanly for use on other platforms. For more control over how to add music to a video on an iPhone – including importing your own royalty-free tracks, adjusting volume and fade, and exporting for YouTube or Instagram without copyright issues – Movavi App is the better mobile tool. It accepts any local audio file, includes a built-in cleared music library, and exports a standard MP4 file that works on every platform.
