Audio Tools
A hub for the audio tools. Pick one below to extract audio from a video, replace a video's audio track, or trim audio to a range.
Why Use Our Audio Tools?
Extract Audio from Video
Pull the audio track out of any video file and save it as a standalone MP3, ready for podcasts, samples, or editing elsewhere.
Replace a Video's Audio Track
Swap out the existing audio on a video for a new track - voiceovers, music, or a cleaned-up recording - while keeping the original video untouched.
Visual Waveform Trimming
Trim audio by dragging a region directly on the waveform, with live start, end, and duration readouts instead of guessing timestamps.
MP3 or WAV Output
Choose MP3 for a smaller file or WAV for uncompressed quality when trimming audio.
100% Private
Your videos and audio files are never uploaded anywhere. Everything runs locally in your browser using a WebAssembly build of FFmpeg.
