A video wrapper for your audio

An MP3 contains audio but no video track. This converter adds a static visual and packages both tracks into one MP4 without shortening your song.

Choose landscape for regular YouTube videos or vertical for Shorts-style viewing, then download the finished file.

Quick answers

Before you create

The tool uses practical YouTube-ready defaults, so there is very little to configure.

Does converting MP3 to MP4 change my audio?

The complete audio is carried into the MP4 and encoded as YouTube-compatible AAC audio.

Can I create an MP4 without a cover image?

Yes. A clean default background is used when you do not add artwork.

Which layout should I choose?

Use 16:9 landscape for a standard YouTube upload and 9:16 vertical for vertical viewing.
