Frequently asked questions

How do I convert audio to music video?

Choose your audio file above, then select Convert to music video. The conversion runs locally in your browser and the completed file is ready to download directly to your device.

Is Lumen Convert free to use?

Yes. Lumen Convert is free to use with no account, subscription, credit card, payment screen, or website-imposed daily conversion quota.

Do my files leave my device?

No. Your media is processed locally in your browser. Lumen Convert does not upload, store, or sell the files you choose.

Which formats can I convert?

You can convert WAV and MP3 audio, plus MOV to MP4, M4A to MP3, MP4 to MP3, MKV to MP4, and WebM to MP4.

Is there a file-size limit?

Lumen Convert does not impose an artificial file-size limit. The practical limit depends on your browser, available memory, battery, and free disk space.

Can I create a music visual with my own artwork?

Yes. Add your own image as a local backdrop, adjust its crop and contrast, customise the title and waveform, and export the visual on your device.
