Audio Waveform Image Generator
Turn any audio or video file into a waveform image you can download as PNG or WebP.
About the Audio Waveform Image Generator
Drop an MP3, WAV, M4A, OGG, FLAC or a video file and render its waveform as a crisp image. Choose bars, mirrored bars, a line or a filled shape, set the exact pixel width and height, pick wave and background colours or export with a transparent background, then download a PNG, JPEG or WebP. Perfect for podcast covers, YouTube thumbnails, music release art and audio player placeholders. Audio is decoded with Web Audio in your browser and never uploaded.
