Free video tools
Make videos on the device itself. No upload, no account, no credits.
MP3 to video
MP3 to Video pairs an audio file with a picture, or several that take turns, and saves an MP4 that can be posted to video sites. Landscape suits YouTube, square suits feeds, and vertical suits Shorts, Reels and TikTok.
Without a picture, the tool draws a dark cover with a gradient music note and the title of the track, so a song or a podcast episode can be published as a video even without artwork.
Nothing is uploaded
The audio is read, the frame is drawn and the video is encoded inside the browser tab, so recordings that are not yet public stay private, and there is no queue.
Works with the AI audio generator
Voice-overs made with the AI audio generator can be turned into a video here, for sites that do not accept plain audio files.

Is it free?

Can I make a vertical video?
