Why convert MP3 to MP4?
YouTube, Instagram, TikTok and many other platforms only accept video, not plain audio. Converting MP3 to MP4 turns your song, podcast episode or voice recording into a video with a cover image or a clean background, so you can upload it anywhere videos are accepted.
- You want to publish a podcast episode or song on YouTube.
- You need to share audio on a platform that only accepts video.
- You want to add artwork or a cover image to a recording.
Tips for the best result
- Add a cover image (JPG, PNG or WEBP) for a much nicer result; without one, we use a clean dark background.
- The video lasts exactly as long as your audio.
- Besides MP3, you can also upload WAV, M4A, AAC, OGG or FLAC files.
