Crop a video to any size

A vertical clip for tomorrow's reel

You've got a great horizontal recording from last weekend's hike — a sweep across the valley, your friend laughing in the corner. You want to post it as a Reel, but Instagram's vertical format will black-bar the sides into oblivion. You need a 9:16 crop that focuses on your friend.

You drop the MP4 in, hit the 9:16 preset, drag the now-locked rectangle until your friend sits dead-center. The dim mask around the rectangle shows you exactly what gets cut. One click, a few seconds of processing, and you've got a vertical video sized perfectly for the Reel — without a watermark, without losing the moment.

You upload it from your laptop and go to bed. The next morning the post has 800 likes.

Cleaning up a screen recording

You're putting together a product walkthrough for a client. The screen recording you took includes the whole desktop — taskbar, browser tabs, even the dock. None of that needs to be in the video; you just want the app window.

You upload the recording, scrub to a frame where the app is in its "hero" state, drag the crop rectangle to fit just the window. The pixel readout shows 1280 × 720, which is what you wanted anyway. Apply, download, drop into your slide deck.

If your client asks for a tighter crop later, you've still got the original — the tool never touches your source file.

Re-using old family footage

Your cousin asked for a clip from last summer's barbecue to put in his wedding montage. The video you've got is in 4:3 (your dad's old camcorder) and the wedding montage is 16:9. The faces you want to keep are in the middle of the frame.

You upload, lock 16:9, drag the rectangle to the people, save. It takes a minute. The trimmed clip slots straight into the montage and nobody notices it started out a different shape.
