Crop any video precisely, right in your browser.
Upload a video, drag the handles to select the area you want, optionally lock an aspect ratio, then export. No upload to a server, no API calls — everything happens on your device.

How does the selection work?
Drag inside the highlighted box to move it, or drag any of the four corner handles to resize it. The numbers below the video update live, and you can also type exact X, Y, width, and height values if you need a precise crop.
What does the aspect ratio dropdown do?
Leave it on Free to resize the selection however you like. Pick a ratio like 1:1 or 16:9 and the corner handles will keep that exact proportion as you drag, so you don't have to do the math yourself.
Why does cropping take a while?
The crop plays through your video in real time while a canvas redraws only the selected region, and the browser records that canvas — along with the original audio — into a new file as it goes. A two-minute video takes about two minutes to crop.
Nothing leaves your device
This tool decodes and re-encodes your video entirely inside your browser using the Canvas and MediaRecorder APIs. The file you open here is never transmitted to or stored on any server.
