Video Crop Tool

Cropping video frames removes unnecessary edges and adjusts aspect ratios for different platforms. Whether you're preparing a vertical phone video for horizontal screens or removing distracting backgrounds, this tool lets you crop to exact pixel specifications or predefined social media aspect ratios.

Multi-platform aspect ratios

Different platforms demand different aspect ratios—YouTube prefers 16:9, Instagram Stories and TikTok use 9:16 (vertical), Instagram feed often uses 1:1 (square), and widescreen cinema uses 21:9. This tool includes instant presets for all these ratios, so you can crop with one click rather than calculating dimensions manually.

Precise control

For custom crops, specify exact pixel coordinates for the crop region—position (X and Y), width, and height. This precision lets you remove specific objects, frame subjects exactly, or match exact requirements. Preview shows you exactly what the output will look like before committing to the crop.
