Free Waveform Video Generator — Turn Podcast Audio into Video

Turn any podcast episode, interview or voice note into a share-ready video in minutes. Upload your audio and cover art, add a title, pick a waveform style and colors, and download a watermark-free MP4 — no sign-up, no payment, no trial limits.

Unlike most podcast to video converters, nothing is uploaded to a server: the video is rendered entirely inside your browser, so your files never leave your device. That keeps your unreleased episodes private and makes the tool work at full speed regardless of your connection.

The scene is built for social feeds: rounded cover art, episode title and subtitle, a live waveform that reacts to your voice, and an episode progress bar. Choose vertical 1080×1920 for Reels, TikTok and Shorts, square 1080×1080 for feed posts, or horizontal 1920×1080 for YouTube.

How to use

1

Upload your audio (MP3, WAV, M4A, AAC, OGG or FLAC — up to 10 minutes) and a JPG/PNG cover image.

2

Type the title and subtitle, then pick a waveform style, position, color theme and video size. Press "Listen" to preview live.

3

Hit "Generate Video" — recording runs in real time — then download your MP4 (or WebM) with no watermark.

FAQ

Is this waveform video generator really free? Is there a watermark?

Yes — it is completely free and the videos have no watermark. There is no sign-up, no payment and no trial limit; you download the finished MP4 directly.

Is my podcast audio uploaded to a server?

No. Your audio and cover image never leave your device — the video is generated entirely inside your browser, which also makes it private and independent of your internet speed.

Which audio formats and lengths are supported?

Audio: MP3, WAV, M4A, AAC, OGG and FLAC, up to 10 minutes. Cover art: JPG or PNG (square works best). Output: MP4, or WebM if your browser cannot record MP4 — every major platform accepts both.

How long does it take to turn audio into video?

Recording runs in real time: a 4-minute episode takes about 4 minutes. Keep the tab visible while it records — you can watch the progress bar and cancel at any time.

Which video sizes can I create for social media?

Vertical 1080x1920 for Reels, TikTok and Shorts; square 1080x1080 for feed posts; horizontal 1920x1080 for YouTube. You pick the size before generating.
