Image Cropper
Upload an image, drag a crop rectangle on the canvas, or type exact pixel values for left, top, width, and height. Preview the result and download the cropped image. Works with PNG, JPEG, and WebP. Runs entirely in your browser.
Crop a selected image locally by entering pixel coordinates or dragging a selection over the preview, then export the selected rectangular region from a browser canvas.
How to crop an image
- Choose an image and wait for its dimensions to load.
- Set left, top, width, and height values or drag on the preview to define a rectangle.
- Crop the selected region, review the result, and download it.
Cropping behavior
Coordinates are interpreted in the image’s natural pixel space. Width and height are clamped to the remaining image bounds when the selection extends past the right or bottom edge.
The result is rendered through canvas. The download filename uses the original extension, but actual canvas encoding behavior is controlled by the browser.
Privacy and limitations
The selected image and crop operation stay in your browser. Nothing is uploaded, and browser canvas memory limits can affect extremely large images.
