What size should a YouTube Short be?

Vertical 9:16, 1080 × 1920 pixels. That is the size this Shorts maker exports.

Can I turn a long screen recording into a Short?

Yes. Drop the recording in, then use Split and the trim handles to keep only the best part. Speed it up to 1.5× or 2× to fit more in.

Can I add a voice-over?

Yes. Record your own voice while the video plays, or type a script and pick one of 14 AI voices. Music is turned down automatically while the voice plays.

How do auto captions work?

One click turns your voice-over into timed captions, with styles like karaoke word highlighting. The audio is processed on our server and deleted right after, and you can edit every caption.

Yes. There is no sign-up, no watermark and no limit on exports. Editing and exporting run in your browser, so your videos stay on your device.

Which files can I use?

JPG, PNG, WebP and HEIC images, MP4, MOV and WebM videos (including iPhone screen recordings) and MP3, M4A or WAV music, up to 500 MB each.
