Check what a centered crop will keep

Look at where your subject sits before you process the clip. A centered 9:16 crop removes the outer edges of a wider video; it doesn’t follow someone as they move across the frame.

For example, two speakers at opposite ends of a landscape shot may not both fit. If you need both faces in view, choose a more tightly composed source clip before resizing.

Make a vertical copy for TikTok

Add one MP4, WebM, MOV, AVI or MKV file, up to 500 MB. If an accepted file won’t preview or process, its video encoding may still be incompatible.

Keep MP4 selected under Output and Resolution set to Original for this workflow. You’ll still get the 1080 × 1920 resize. Leave the other editor controls unchanged unless you also want to adjust the picture.

Click Process Resize Video for TikTok. If your device can’t finish the task, try a smaller file or check the price under Cloud · credits before continuing.

Play the result and open the saved copy before you post it. Follow the subject through the whole clip and check any existing captions near the edges. The tool also attempts a download after five seconds; use the result’s download control if you need another copy.

Questions about resizing for TikTok

No. There’s no Fit Mode selector in the current workspace for this tool. Use it when a centered crop can keep the parts of the picture you need.

No. This tool takes one video at a time.

The publishing app can place buttons, captions, and other interface elements over the video. Keep important text away from the outer edges and review the in-app preview before posting. Resizing cannot guarantee that every interface overlay leaves your text unobstructed.
