About This Tool
Free audio waveform viewer online — upload an MP3, WAV, or other audio file and instantly see its waveform rendered on a canvas, entirely in your browser. The tool uses the Web Audio API to decode the audio locally and draw the amplitude over time, so no file is ever uploaded to a server. Musicians, podcasters, and video editors use this to quickly check an audio file's shape, spot silence or clipping, and get a visual reference before editing. See duration, sample rate, and channel count alongside the waveform, and download the waveform as a PNG image.
