Resize a video for TikTok

A wide video on TikTok
Posted as it is, a 16:9 video plays in a band across the middle of the screen, with empty space above and below. Made 9:16, it fills the screen, which is what people scrolling expect. Cropping a 1920 × 1080 video to 9:16 keeps a 608 × 1080 slice, about 32% of the picture, scaled up to 1080 × 1920: drag it onto the face or the action.
For a podcast or an interview where two people take turns, one crop frames only one of them. That's what Clyper's auto reframe is for, or stack both with the split screen video maker.
Leave room for TikTok's buttons
The caption and username sit along the bottom and the like, comment and share buttons down the right, over your video. Keep faces and on-screen text toward the middle. Check a frame with the safe zone checker before you post.
Questions
What size should a TikTok video be?
1080 × 1920 pixels, 9:16, which fills a phone screen. On the web TikTok takes videos from 720 × 1280, and Creator Rewards' extra reward asks for 1080p or more, so 1080 × 1920 covers both.
How do I resize a horizontal video for TikTok?
Choose it here; 9:16 is already picked. Crop to fill and drag the picture to what matters, or pick Blurred background to keep all of it. Press Resize video and download the 1080 × 1920 MP4.
Crop or blurred background?
Crop when one person or thing is the point: it fills the screen, but a 16:9 video keeps only about 32% of its picture. Blurred background when everything matters, like slides, a wide shot or a screen recording: the whole picture sits in the middle, smaller.
How long can a TikTok be?
Up to 60 minutes uploaded in the app, and 30 on the web. Creator Rewards only counts videos of at least 1 minute. This resizer works on up to 30 minutes at a time.
Will TikTok cover part of my video?
Yes: the caption, the buttons down the right side and the bar along the bottom sit over the video. Keep faces and text out of those edges; the safe zone checker shows where they fall.
Is my video uploaded?
No. It's resized in your browser, on your device, and saved there as an MP4 with its sound. Free, no watermark.
