Is my audio uploaded?
No. The file is decoded and rendered locally with browser APIs. Convertr does not receive the audio, samples, waveform data, filename, or metadata.
Which audio formats work?
MP3 and WAV work in most modern browsers. M4A/AAC, OGG, and Opus depend on your browser and operating system decoder support. Unsupported files show a local error message.
Can I export a transparent waveform?
Yes. Enable transparent background before exporting PNG or SVG. The PNG keeps transparency when your browser supports canvas export.
What is SVG export best for?
SVG is useful for documentation, covers, and graphics tools because it stays sharp when resized. The SVG contains only generated shape data and no audio samples.
