Crop an MP4, MOV or WebM video: drag the frame on a still or pick 9:16 for TikTok, Reels and Shorts, 1:1 or 4:5 for a feed, 16:9 for YouTube. Or keep the whole picture and fill the edges with black bars or a blurred background. All in your browser.

How it works

  1. Choose a video or drag it onto the page.
  2. Pick the aspect ratio and how to fit: crop to the frame (drag it on the still) or keep the whole picture with bars or a blurred background.
  3. Click Crop and download the video in the same format (MOV is saved as MP4).

Frequently asked questions

How do I make a horizontal video vertical?

Choose 9:16. “Crop to the frame” cuts out a vertical part — drag the frame to keep the subject. “Blurred background” keeps the whole picture and fills the top and bottom with its blurred copy.

Is the sound kept?

Yes, the sound is kept as is. Tick “Remove audio” if you need a silent video.

Is it free?

Yes. All tools are free, with no sign-up and no watermarks.

Are my files uploaded to a server?

No. Everything runs in your browser, so your files never leave your device.
