VIDEO TOOLSCrop a Video Online
Crop a browser-supported video when you need to remove unwanted edges or focus the frame on a smaller area. Load the video, choose the crop region and export the adjusted copy directly from your browser. Cropping can help remove empty borders, reframe a shot or prepare footage for a different layout.
Cropping changes the visible frame, not the duration of the video. Choose the crop carefully so important subjects, captions and interface elements remain inside the final image. A very small crop region may produce a lower-resolution result because fewer source pixels remain. Browser and device capabilities determine which source formats can be decoded and how efficiently the new video can be processed.
The source video is handled locally in your browser instead of being uploaded to a remote processing server. If the framing is correct but the clip is too long, use the Video Cutter. If the picture is sideways, use the Video Rotator & Flipper. For a smaller file without changing the framing, use the Video Compressor.
Reframing video for different screens
Crop a video to common aspect ratios such as 16:9, 9:16, 1:1 or 4:5 and reposition the frame before processing. Cropping is useful for adapting footage to different screens and social formats while keeping important subjects inside the final composition.
When this tool is useful
Cropping removes unwanted edges and can convert a landscape source into a tighter square or vertical composition. It is commonly used when preparing social content or removing empty borders.
Practical limits and quality checks
Cropping discards pixels. If you crop heavily and then enlarge the remaining image, visible sharpness can drop. Choose the target aspect ratio first and keep important faces, subtitles and on-screen text inside safe areas.
Privacy and responsible use
The crop operation uses the video selected in your browser. Edit only footage you have the right to process, retain the full-frame original, and check that faces, captions and important edge content remain inside the exported crop.
Frequently asked questions
Why can video processing take longer than expected?
Cropping removes pixels outside the selected frame. If the remaining area is enlarged or re-encoded, sharpness can fall, so avoid unnecessarily tight crops and inspect the exported video at its intended viewing size.
Will editing reduce video quality?
Processing time grows with duration, resolution and codec complexity because frames may need decoding and re-encoding. Long 4K files can exceed browser memory on some devices; shorter clips or desktop processing are more reliable.
