How YouTube decides something is a Short

YouTube treats vertical or square videos up to three minutes long as Shorts. A vertical 9:16 video at 1080×1920 fills the whole screen in the Shorts player, which is what viewers expect when they swipe.

Repurpose your long videos

Shorts are a good way to bring new viewers to a channel. Cut the best moment from a longer video with the trimmer, then send it here to make it vertical. Use Fill the frame when the subject is centered, or Fit whole video to keep the full shot with space above and below for captions.

Is my video uploaded anywhere?

No. Kliprio runs entirely in your browser using your device's built-in video encoder. Your file is never sent to a server, so it stays private and nothing is stored on our side.

Is Kliprio really free?

Yes. Kliprio is free to use and is supported by ads shown on the page, never inside the tool or on the download button. There's no watermark and no account.
