How to Merge Audio and Video Online
Upload clips, set the order, pick a merge mode, and export — all in three steps.
- 01
Upload your clips
Add two or more audio or video files. Choose pure audio, pure video, or separate video and audio tracks depending on how you want them combined.
- 02
Order files and pick an export format
Drag clips into playback order on each track. Select MP3, WAV, MP4, or WebM before you merge.
- 03
Merge, preview, and download
Processing runs in your browser with ffmpeg.wasm. Preview the merged file, then sign in to download when it looks right.
Why Use Our Free Media Merger Online
One page for audio-only joins, video-only joins, and separate video plus audio tracks — reorder clips, pick your export format, preview, then download. Drag clips into playback order, preview the full join in your browser, and export one continuous MP3 or WAV track without opening a desktop editor.
Mixed uploads, one export choice
Drop MP3 beside MOV or WAV beside MP4 — the merger normalizes on export. Pick MP3 or WAV for audio-only output, or MP4 and WebM when you need a playable video file. MP3 suits hosts and phone libraries; WAV hands off cleanly to Audacity, Logic, or Premiere — export from the same browser merge workflow.
Browser merge with preview before download
Clips stay on your device while ffmpeg.wasm runs locally. Watch or listen to the full merged result on the page, then sign in to save the file. No desktop software to configure — open Media Merger in a modern browser, adjust settings in the same tab, and export when the preview looks right.
