Crop a video to 9:16, 1:1, or 4:5 — free and local
A horizontal clip does not fit a vertical feed. Choose an aspect ratio and Cutmoor scales the video to cover the frame, then crops the overflow from the center. Choose Pad instead if you need the whole frame visible, for example a screen recording or a wide shot you cannot lose.

Crop & resize: common questions
What size should a Reel or Short be?
Use 1080 x 1920 (9:16). That is the baseline for Instagram Reels, YouTube Shorts, and TikTok. A 720 x 1280 export is smaller and still accepted, but 1080 x 1920 is the safe choice for a crisp upload.
Should I crop or pad?
Crop when the important subject is in the middle and the edges are expendable. Pad when the whole frame matters, such as a tutorial, a screen recording, or a group shot. Padding adds bars; it does not invent picture outside the original frame.
Does resizing reduce quality?
Any re-encode loses a little quality. Upscaling a small clip to 1080p cannot add detail. For the best result, start from the highest-resolution source you have and export once, at the final size.
Can I choose a custom size?
Yes. Pick Custom and enter the width and height in pixels. Keep both dimensions even numbers; most video encoders require it.
