How to crop videos online
Cropping a video lets you remove unwanted areas from the sides, top, or bottom of your video. Unlike trimming which cuts from the start or end, cropping removes pixels from within the frame. This is useful for removing letterboxing, adjusting aspect ratio, or focusing on a specific area of the video.
This free video cropper processes everything in your browser using FFmpeg WebAssembly. Your video files are never uploaded to any server, ensuring complete privacy. Enter exact pixel values for x/y offset and width/height to precisely control which portion of the video to keep.
The cropper supports MP4, WebM, MOV, and AVI formats, and preserves the original format in the output. The first crop requires a one-time download of the video engine (~30 MB), after which subsequent crops start immediately. For center cropping, sensible defaults are automatically calculated based on common video sizes.
