Audio to Video

Turn an audio file into an MP4 video with a still background, so it can be saved to Photos or shared anywhere a video is expected. Or just convert between audio formats.

Your audio never leaves your device. Conversion happens locally in your browser.

Frame Rate

The background is a still image, so a higher frame rate adds processing time and file size without improving quality. 1 fps is recommended.
