What can this tool do?
Turn a track into a good-looking image: a waveform shows how the sound rises and falls, bars and mirrored waveforms work well as podcast covers or progress-bar backdrops, and a spectrogram reveals the frequency content and timbre differences. Customise the main colour, background, canvas size, bar count and glow; enable the playhead to track playback in real time with the player below. The result downloads as a PNG for covers, slides or social posts, all locally in your browser.
FAQ
Which formats are supported?
Anything your browser can decode — usually MP3, WAV, OGG and M4A, with FLAC and AAC supported in recent browsers. If a file will not parse, convert it to WAV or MP3 first.
Will the exported image look blurry?
No. The canvas renders at the exact pixel size you enter, and the exported PNG is that size — fine for retina screens and print. The 1200×320 default suits covers and web banners; raise the width above 2000 for higher resolution.
