Add audio to video
Upload a video and an audio file, and mux them into one video. The video stream is copied losslessly; if the video already has audio, it is replaced.
Upload a video and an audio file, and mux them into one video. The video stream is copied losslessly; if the video already has audio, it is replaced.
Provide a video and an audio file, and the tool muxes them into one output with the video carried over untouched. Silent screen recordings gain narration, muted clips gain music, and the picture never pays a quality price.
Record narration with the voice recorder, silence the original track with remove audio, then combine here: a complete voiceover pipeline that never leaves the browser.
The output follows the video’s length; trim the audio first with the trim tools if you want a specific section to land.
No, the video stream is carried over as-is; only the muxing changes.
No, the combination happens locally.
