Important limitations
Cropping changes the crop box; it does not permanently erase content outside the visible area. Do not use it as secure redaction.
Privacy and file handling
This tool is designed to process supported files locally in your browser; the static website does not provide server-side file storage. Your browser still downloads the JavaScript libraries required for some operations from third-party content delivery networks. See the Privacy Policy for details. Do not use the output without checking it, and keep your original file.
Frequently asked question
Keep the original if hidden content must be removed rather than merely hidden.
