A Simple Visual Format for Audio
Audio Needs a Video Canvas
Some publishing channels require a video file even when the source is audio. A waveform or audiogram supplies a clear visual layer without filming a host or inventing a person.
Keep the Workflow Audio-Only
The converter uses abstract graphics and a title derived from the audio filename. It does not request portraits, guest photos, avatars, or any other source for face manipulation.
Know the Rendering Time
The WebM is recorded locally in real time, so a five-minute selection takes about five minutes after upload and decoding. Keep the tab open until recording finishes.
Choose the Right Canvas
Select 9:16, 1:1, or 16:9 before rendering. The tool changes the canvas dimensions; it does not automatically publish, transcode, or verify a platform's current upload rules.
From Audio to WebM in 4 Steps
Upload Supported Audio
Sign in and upload an MP3, WAV, M4A, AAC, OGG, or FLAC file up to 50MB and 30 minutes. Codec decoding still depends on browser support.
Choose a Graphic Layout
Select a dynamic audiogram, a classic waveform, or a title card with frequency bars. No transcription or caption generation is included.
Set Format and Duration
Choose 9:16, 1:1, or 16:9, then render the complete uploaded segment, the first 60 seconds, or a custom duration from the beginning.
Render and Download
Keep the tab open while Canvas, Web Audio, and MediaRecorder produce a video/webm Blob with audio. Preview it as a video, then download the .webm file.
Podcast Video Tools With Clear Boundaries
Start with the audio-only WebM renderer, then use separate tools only when you actually need their distinct capability
