Cropping a video removes unwanted areas from the frame -- black bars, borders, watermarks from other tools, or distracting elements at the edges. Unlike trimming (which cuts time), cropping cuts the visible area of each frame.

MiOffice crops videos in your browser using FFmpeg WebAssembly. No upload, no watermark, no account needed.

Frequently Asked Questions

Can I crop a video to a specific aspect ratio?
Yes. Set the width and height to your desired ratio. Common ratios: 1920x1080 (16:9), 1080x1080 (1:1 square), 1080x1920 (9:16 vertical). Use the X/Y offset to position the crop area.
Can I remove black bars from a video?
Yes. Set the crop dimensions to exclude the black bars. For example, if a 1920x1080 video has 100px black bars top and bottom, crop to 1920x880 with Y offset 100.
Does cropping reduce video quality?
The video is re-encoded during cropping with high-quality H.264 settings. The visual quality remains excellent. The file size may change depending on the crop dimensions.
