Crop Video
Upload an MP4, set the crop area, and download the result — free, no account required.
FloxerFile crops an MP4 video to the exact width, height, and position you specify, directly on our servers. Useful for removing black bars, focusing on part of the frame, or changing aspect ratio. No software to install, no data stored after conversion.

Frequently asked questions
- Is FloxerFile free to use?
- Yes. Cropping videos is completely free, with no account required.
- How do I know my video's dimensions?
- Most media players and file properties dialogs show a video's resolution (e.g. 1920×1080). Use that to figure out the crop area you want, measured from the top-left corner.
- What happens if I enter a crop area outside the video?
- The tool shows a clear error rather than a broken file — make sure your width, height, and offset fit within the original video's dimensions.
- Are my files kept private?
- Your files are processed on our servers solely to perform the crop. They are deleted automatically once the download is complete and are never shared or stored long-term.
