Frequently asked questions
Why turn audio into a video?
Social networks don't accept plain audio posts. A video with a moving waveform makes podcasts, songs and voice notes shareable on Instagram, TikTok, YouTube, X and WhatsApp, and catches the eye in the feed.
How long does it take?
About as long as the audio on a laptop, longer on phones, because the video is encoded in your browser. For best results use clips under a few minutes, such as a highlight or chorus.
What is the difference between waveform and spectrum bars?
Waveform draws the sound wave as it plays, which suits speech and podcasts. Spectrum bars show bass on the left and treble on the right jumping with the music, which suits songs.
Is my audio uploaded?
No. The background is drawn by your browser and the MP4 is encoded with a local copy of FFmpeg, so your audio and image never leave your device.
Are my files uploaded anywhere?
No. Audio to Waveform Video runs entirely in your browser. Your files are processed on your device and are never sent to a server.
Is there a file size limit?
No fixed limit. The only limit is your device's memory. Very large files work best in a desktop browser.
