Audio to video maker
Social platforms don't accept audio files; they want video. Turn your recording into a video with a title, a subtitle and a waveform that moves with the sound, in square, vertical or landscape.
Free · no sign-up · your file is processed in your browser and never sent to a server

How to use
- Choose your audioA podcast episode, an interview clip or music; pick a recording of up to 15 minutes. Shorten long recordings first with the MP3 cutter.
- Design the lookChoose bars, wave or circle; square, vertical or landscape; a dark or light background and an accent color, and type your title. The preview updates instantly.
- Create the videoPress "Create video"; the video is drawn and encoded frame by frame in your browser. Watch it and download.
Which size for which platform?
| Size | Resolution | Good for |
|---|---|---|
| Square 1:1 | 720 × 720 | Feed posts, messaging apps |
| Vertical 9:16 | 720 × 1280 | Stories, short vertical videos |
| Landscape 16:9 | 1280 × 720 | Video platforms, presentations, websites |
For a good audiogram
- Pick a 30–90 second segment that makes sense on its own; long videos in a feed are rarely watched to the end.
- Put the topic in the title and the speaker's name or episode number in the subtitle.
- For platforms watched on mute, add the speech as subtitles: Transcription turns speech into time-stamped subtitles.
Technical details
The video is produced at 30 frames per second. If your browser supports WebCodecs, it's encoded faster than real time (MP4: H.264 + AAC, WebM: VP9 + Opus). If not, the tool records the video in real time; in that case it takes as long as the audio and the output is WebM.
Privacy: your recording never leaves your device
Everything happens in your browser. Your file is not sent to Voiser's servers or stored anywhere, and it's cleared from memory when you close the tab. That's also why the tool stays fast on a slow connection.
Common questions
Does the video have a watermark?
No. The video is made entirely in your browser; no Voiser watermark is added.
How long can the video be?
Up to 15 minutes of audio. For social videos we recommend picking a short segment.
Why isn't the MP4 option working?
MP4 needs your browser's H.264 video encoder. If it isn't available, the tool makes WebM instead; most platforms accept WebM, or it can be converted to MP4.
Can I add my own logo or photo?
Not yet; you can choose the title, subtitle, colors and look. For videos with images and narration, see the text to video studio.
