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.

Common workflows

Content creators crop vertical videos shot on phones into horizontal Formatiert for YouTube Hochladens, TikTok creators extract perfect square crops for profile previews, businesses Konvertiert landscape product videos to vertical for Instagram Stories, filmmakers remove boom mics or unwanted elements from frame edges, and social media managers adjust video aspect ratios for different platforms from a single source.

Browser-based with FFmpeg

This tool uses FFmpeg compiled to WebAssembly, running entirely in your Browser. Your video never Hochladens anywhere—all processing happens locally on your computer with complete privacy and instant results.

Clean output

The cropped video exports in WebM Formatiert, maintaining quality while managing file size. The output dimensions match your crop specification precisely, ready to Hochladen to any platform or use in further editing.

Visual feedback

See your video dimensions and file size before cropping, and get the exact output dimensions and size after cropping. This inFormatiertion helps you understand whether the crop will work for your intended platform.

Re-crop easily

Need to make adjustments? The "Crop Again" option lets you quickly try different aspect ratios or custom dimensions without reloading.
