Convert MP3 to MP4

YouTube and most social apps only take video. Put your audio into an MP4 with a cover — yours or an automatic one — without uploading your audio.

Why turn an MP3 into an MP4?

Podcasts, music, long voice notes: YouTube, TikTok, Instagram and WhatsApp status all ask for video. Here your audio becomes an MP4 with a still HD image (1280×720), ready to publish — without touching any server.
