Frequently Asked Questions

How do I convert an M4A to MP4?

Add the M4A, optionally add a cover image, and press Create. The video renders in about the length of the audio and then downloads.

Can I turn an iPhone voice memo into a video?

Yes. Voice memos are M4A files. Share the memo to this page on your phone or computer, add an image, and export.

Does it export MP4 or WebM?

MP4 where the browser supports MP4 recording (Safari), and WebM elsewhere (Chrome, Firefox). Both upload fine to YouTube, TikTok, and Instagram.

Will the audio quality change?

M4A is AAC, which video containers carry natively, so the audio is kept at high quality in the video's audio track.

Are my files uploaded anywhere?

No. The converter runs entirely in your browser: your file is decoded and re-encoded on your own device, and nothing is sent to a server. That is also why it is fast — there is no upload wait and no download wait, just the conversion itself.

Is the converter free?

Yes, completely free with no signup, no file-size paywall, and no watermark. Once your audio is converted, you can turn the track into a music video with Solmi's AI music video generator — also free to start.
