Image + Audio to Video: Guide
- Intent
- Create a video from an image and audio online: turn cover art + an audio file into an MP4 you can share in video-first apps (local processing, no upload).
- What it does
- Uses FFmpeg in your browser to combine one image and one audio track into an MP4 (H.264 + AAC).
- Key features
- MP4 output, Audio < 5 minutes, In-browser FFmpeg processing
- Privacy
- Your media stays on your device. This page downloads the FFmpeg WebAssembly engine; files are never uploaded.
- Best for
- Podcasters making a quick teaser video from cover art + a short clip
- Sharing voice memos or music previews where MP4 is required
- Anyone searching 'add audio to image video' or 'image audio to video'
- Why this tool
- Local-first FFmpeg processing: your files are not uploaded
- Faster than opening a full video editor for a one-off MP4
- Simple defaults and a predictable MP4 output
How to use
- 1Choose an image file (cover art, screenshot, or any still).
- 2Choose an audio file (must be under 5 minutes).
- 3Click Create video and wait for processing to finish.
- 4Download the MP4 and share it anywhere.
Common mistakes
- Audio longer than 5 minutes (this tool enforces a 5-minute limit).
- Using Safari/iOS browsers that lack SharedArrayBuffer support (FFmpeg may fail to load).
- Processing very large files on low-memory devices (can crash the tab).
