What is a video cropper?

A browser-based tool that crops your video frame. Input: a video file plus crop parameters (X/Y offset, width/height percent). Output: the cropped video. Use it to remove black bars or focus on key regions.

How do the crop parameters work?

4 sliders control the crop box: X offset (left edge 0-90%), Y offset (top edge 0-90%), width (10-100% of frame), and height (10-100% of frame).

Which video formats are supported?

Any format the browser can play natively: MP4 (H.264), WebM, OGG, and more. MP4 is recommended.

Does cropping change the video codec?

The front-end crop remuxes the clip without expensive re-encoding. Output resolution depends on the crop region size.

Is there a file size limit?

Limited by browser memory; keep videos under ~500MB.

Is my video uploaded to a server?

No. Everything happens locally in your browser. Your video never leaves your device.
