Vertical video converter

1. Choose your video, or drop it on the phone. MP4, MOV and WebM work.
2. Pick Crop or Fit. With Crop, drag the picture (or the slider) until what matters is in the frame.
3. Choose the part to convert, up to 5 minutes, by dragging the ends of the bar or typing the times.
4. Convert, then download your 1080 × 1920 MP4.

Crop fills the whole screen, which is what the apps are made for. From a 16:9 video it keeps a slice about 32% of the width: plenty for one person talking to the camera, as long as they stay in it.

Fit keeps the whole picture, on a blurred, darkened copy of itself. Nothing is cut, but a 16:9 picture fills only about 32% of the screen's height, so faces and text are small. Use it for wide shots, slides and screen recordings, or people sitting far apart.

A fixed crop works while the person in it stays put. When they lean out of the frame, or two people take turns talking, it shows the wrong person, or no one. By hand, the fix is cutting the video at every change and moving the crop each time.

Clyper does that for you: it finds who's talking in every shot, keeps them in the frame as they move and switches when someone else speaks. See how Clyper's auto reframe works, or framing the speakers in podcast clips.

TikTok, Reels and Shorts all fill the screen with a 9:16 video, and 1080 × 1920 is that shape in full HD. YouTube counts square and vertical videos of up to 3 minutes as Shorts. Instagram takes Reels of up to 20 minutes, but doesn't recommend Reels over 3 minutes to new audiences.

Instagram also shows Reels with borders or another app's watermark less often, and TikTok keeps clips showing someone else's watermark out of For You. The converter adds neither. Before you post, check your captions are clear of the apps' buttons with the safe zone checker.
