About Crop Video
This online tool allows you to crop videos directly in your browser. Perfect for removing unwanted edges, zooming into specific areas, or changing aspect ratio for social media. Choose preset aspect ratios or define custom crop dimensions. All processing happens locally for complete privacy.
What video formats are supported?
You can upload MP4, WebM, MOV, and other common video formats. The cropped video can be exported as MP4 or WebM.
How do I choose the crop area?
You can use preset aspect ratios (Square, Portrait, Landscape, Cinema) with automatic positioning, or define custom width, height, and position in pixels.
What aspect ratios are available?
Preset options include Square (1:1) for Instagram, Portrait (9:16) for TikTok/Stories, Landscape (16:9) for YouTube, and Cinema (21:9) for widescreen.
Can I position the crop area?
Yes! For preset aspect ratios, you can choose from 9 positions: center, corners, and edges. For custom mode, specify exact X and Y pixel coordinates.
Does cropping reduce video quality?
Cropping itself doesn't reduce quality - you're just selecting a region. However, re-encoding may slightly affect quality. Choose High quality setting for best results.
What happens to video duration?
Cropping only affects the frame dimensions, not the duration. The entire video is cropped from start to finish.
Is my video file safe?
Absolutely! All video processing happens directly in your browser using FFmpeg.wasm (WebAssembly). Your video is never uploaded to any server. Everything stays private on your device.
How long does cropping take?
Cropping time depends on video length and output quality. A 30-second video typically takes 30-60 seconds to crop and re-encode.
