# Audio to video, beautifully

Turn a podcast clip, an interview, a voice note or a song into a video people stop scrolling for: a wave that moves with the voice, your cover art and captions that light up word by word. Square, vertical or widescreen, exported as an MP4 on your own device.

* 17 templates, 9 moving waves
* Word-by-word captions
* No upload of your recording

Examples

## One recording, any look you like

Every card below is the studio itself playing a template, not a recording of it. Hover to play one; click it to start with that look and your own audio.

### Looks like your show in seconds

Seventeen templates drawn live with your own cover, title and words. Add cover art and the colours follow it; save the look under My styles and reuse it on every episode.

### Captions that keep up

Make captions writes out the clip with timings, and words light up as they’re spoken. Correct any line by typing over it, then download the same captions as SRT or VTT.

### Your recording stays with you

The audio, cover art and photos are turned into video in your browser. Only Make captions sends the chosen clip’s sound to our speech service, and it isn’t kept. Free, no watermark, no account.

How it works

## How to turn audio into a video

1. ### Choose the shape and the recording
Pick Square, Vertical, Portrait or Landscape on the card, then press Choose audio (Ctrl+O or ⌘+O) or drop a file. MP3, M4A, WAV, FLAC, voice memos and the sound of a video all open.
2. ### Find the moment
Drag the window on the timeline under the preview, or open Audio and press Best 30 s to jump to the liveliest talking. One video holds up to 10 minutes.
3. ### Make it look like yours
In Text, add Cover art, a Title and the Show or speaker. Browse Templates, change the movement in Wave, and fine-tune colours and fonts in Style.
4. ### Add captions
In Captions, press Make captions. The clip’s sound is sent to our speech service to be written out; fix any word by typing over it and choose Highlight, Pop, Box or Plain.
5. ### Export the video
Press Export (Ctrl+Enter or ⌘+Enter), choose 1080p or 720p and 30 or 60 fps, then Export video. Download video saves the MP4; on a phone, Share sends it straight to an app.

## Questions about audiograms

The recording is turned into a video on your device. Only captions from speech send anything anywhere: the chosen clip’s sound, to be written out, and nothing is kept.

### What is an audiogram?

Here it means a short video made from audio: cover art or a photo, a waveform that moves with the sound, and captions of what is said. Podcasts and radio shows use them to share clips where only video plays. It isn’t the hearing-test chart of the same name, which this site has nothing to do with.

### How do I make an audiogram?

Open a recording above, move the window on the timeline to the moment you want, add your cover art and a title in Text, press Make captions, then Export. The guide to making an audiogram covers choosing the moment and the sizes for each platform.

### How do I turn an audio file into a video?

Open it here and the studio draws a video around it straight away, with a template, a moving wave and room for a picture. Choose how much of the recording to use, then press Export to save an MP4 with the sound inside.

### How do I convert MP3 to MP4 with a picture?

Open the MP3, press Cover art in the Text panel and choose your picture, drag the timeline handles to cover the whole track, and export. The MP3 to MP4 page covers picture sizes and file size.

### Is it really free, with no watermark and no sign-up?

Yes. There is no account to create, nothing to pay, and the video carries no watermark or logo. The limits are 10 minutes per video and fair-use limits on captions.

### Are my files uploaded anywhere?

The recording, cover art and photos are opened and turned into video in your browser, and are never uploaded. The one exception is Make captions: pressing it sends the selected clip’s sound, compressed, to our speech-recognition provider through this site so the words can be written out. Neither we nor the provider keep it. If you don’t press it, no sound leaves your device.

### Can I upload audio to Instagram?

Not as an audio file on its own: Instagram only plays sound inside a video, or songs from its own library. Make the audio into a vertical video here and post that. The Instagram audio guide explains Stories, Reels and original audio.

### How do I upload an MP3 to YouTube?

YouTube only accepts video, so give the MP3 a picture first: open it here with Landscape selected, add the artwork and export. Then upload the MP4 in YouTube Studio. The YouTube upload guide also covers copyright claims.

### Does it add captions automatically, and can I download them as SRT?

Captions are made when you press Make captions, not before, because that is the step that sends the clip’s sound to be written out. You can then edit them and download SRT or VTT from the Captions panel. See audio to SRT for using the file elsewhere.

### Which size should I use for Instagram, TikTok, YouTube and LinkedIn?

Vertical (9:16) for Reels, TikTok, Shorts and Stories; Portrait (4:5) for the Instagram and Facebook feed; Square (1:1) for LinkedIn and X; Landscape (16:9) for YouTube and websites. You can switch the shape in Templates and export each one from the same project.

### How long should an audiogram be?

Usually 30 to 60 seconds: one complete thought with a strong first line. The Length buttons in Audio set 15 to 90 seconds, and Best 30 s or Best 60 s finds a lively stretch to start from.

### What is a music visualizer?

A video for a song in which shapes such as bars or rings move with the music, usually around the artwork. The music visualizer makes one, and what is a visualizer explains how it differs from a music video.

### Can I turn a voice memo into a video?

Yes. Save the memo to Files from Voice Memos, open it here, add captions and export. The M4A to MP4 page walks through the iPhone steps.

### How do I add music to a picture?

Open the song first, then add the photo in Style under Background, Photo. Pick the part of the song you want and export. The add music to a photo page has the details, including Android’s built-in option.

### How is this different from Headliner or Wavve?

Those are online services you sign in to, which process your audio on their servers and offer paid plans with more features, such as working from a podcast feed. This studio runs in your browser with no account, keeps your files on your device apart from the clip you choose to caption, and exports without a watermark for free.
