PNG or SVG — which should I use?

PNG is a bitmap that is ready for social posts and video edits. SVG is a vector file that stays sharp at any size, so it suits print, merch and the web, and it opens in Illustrator or Figma for further editing.

Why does a file fail to decode?

The waveform is read with your browser's built-in decoder, which does not support a few niche formats such as AMR or WMA. Convert the file to MP3 or WAV with the Audio Converter first.

Are my files uploaded to a server?

No. Everything runs locally in your browser via WebAssembly. Files never leave your computer and are discarded when you close the page.

Do I need to sign up or pay?

No. The site is completely free, requires no account, has no usage limits and adds no watermarks.
