Most video platforms will not take a bare audio file. This tool pairs your song, podcast episode, audiobook chapter or recording with a cover image (or a solid background with a title) and renders an MP4. Landscape 16:9, square 1:1 and vertical 9:16 are all supported, and because the picture is a still, even an hour-long episode renders quickly.

## How to use

1. Upload one or more audio files
2. Pick a cover image or solid background, set the aspect ratio and add a title if you like
3. Click create video and download the MP4

## Features

- Cover image or solid color background
- Blurred backdrop fills the frame without distorting the cover
- 16:9 landscape, 1:1 square, 9:16 vertical
- Titles render any script or emoji; file names can serve as titles in batch mode
- H.264 + AAC MP4 accepted everywhere
- Low frame rate encoding keeps long audio fast

## FAQ

### Why 1 fps — will it stutter?

The picture never moves, so 1 fps looks exactly like 25 fps while needing far less encoding, which means faster renders and smaller files. If a platform complains about the frame rate, switch to 25 fps.

### Which platforms accept the output?

It is a standard MP4 with H.264 video and AAC audio, which YouTube, TikTok, Instagram, Facebook and other platforms accept directly. Use 9:16 for Shorts, Reels and TikTok.

### Are my files uploaded to a server?

No. Everything runs locally in your browser via WebAssembly. Files never leave your computer and are discarded when you close the page.

### Do I need to sign up or pay?

No. The site is completely free, requires no account, has no usage limits and adds no watermarks.
