Original Podcastools demonstration, reviewed October 2, 2026. Illustrative facts are labeled; exports should be reviewed before publishing.

What you can use and export

Free with no account, trial, or subscription.

Inputs

  • MP3 or WAV clip under 3 MB
  • PNG, JPEG or WebP cover under 1 MB and 16 megapixels

Outputs

  • Playable 1080 x 1080 H.264 MP4 with AAC audio
  • MP4 download

The server renders an actual waveform with FFmpeg and deletes temporary input/output files after the response. No AI provider is used.

Limits and checks

  • The first 60 seconds are rendered; shorter audio keeps its source duration.
  • Rendering times out after 80 seconds.
  • 20 expensive requests per IP per 10 minutes across active tools.
  • Audio is re-encoded to AAC; listen to the result before publishing.
  • The tool does not add captions or remaster audio.
  • Cover art is fitted into the square canvas; the waveform overlays its lower section.
