Frequently asked questions

Is my audio uploaded?

No. The video is made by your own browser, so your song and picture never leave your device.

Which audio files work?

MP3, WAV, M4A, AAC, OGG and FLAC, up to 80 MB and 30 minutes.

What do I get?

An MP4 video (H.264 with AAC sound) in Chrome, Edge and Safari — it uploads to YouTube, Instagram, Facebook and WhatsApp. A few browsers make a WebM video instead, which YouTube also accepts.

How long does it take?

Usually a few seconds to a minute, even for a long song, because the picture doesn't move. Very old browsers record the video in real time instead.

Which size should I pick?

Landscape 16:9 for YouTube, Square for Instagram and Facebook posts, Vertical 9:16 for Reels, Shorts and WhatsApp status.

Can I use any song?

Only upload music you own or have the right to use — platforms like YouTube may block or mute videos with copyrighted songs.

Turn a song into a video in three steps

  1. Choose your audio — a song, podcast episode or voice recording.
  2. Add a cover picture and, if you like, a title.
  3. Pick the size and press Create video, then Download.
