The most common reason is converting horizontal (16:9) YouTube videos into vertical (9:16) format for TikTok, Instagram Reels, or YouTube Shorts. Cropping lets you focus on the most important part of the frame while adapting to different platform requirements.

Trimming changes a video's duration by cutting out the beginning, end, or sections you do not need. Cropping changes the frame by removing areas around the edges. You trim to make a video shorter; you crop to change its shape or focus on a specific area.

YouTube Shorts require a 9:16 vertical aspect ratio (1080x1920 pixels). Our cropper makes it easy to select this ratio and position the frame on the most important part of your horizontal YouTube video.

Cropping itself does not reduce quality. However, if you crop a small area from a low-resolution video, the output may appear less sharp because fewer pixels are being used. For best results, start with the highest resolution source video available.

For the best workflow, trim your video to the desired length first using our video trimmer, then crop to the aspect ratio you need. This two-step approach gives you precise control over both duration and framing.

We support MP4, MOV, WebM, AVI, MKV, and all common video formats. Since YouTube primarily uses MP4 and WebM, your downloaded YouTube videos will work without any conversion.
