Image Cropper

Media Client-side image crop cropper cut trim region selection

This tool runs entirely client-side, in your browser: your data is never sent anywhere.

What it does

This tool lets you crop an image: draw a selection box directly on the picture with your mouse (or finger on touch devices), adjust it, and export only that region as a new image. Everything runs locally in your browser — no image is ever uploaded.

How it works

After choosing an image, click and drag anywhere on the picture to draw a rectangular selection.
The selection is shown as a dashed overlay; drawing a new one replaces the previous selection.
Clicking Crop selection maps the selection's on-screen coordinates back to the image's real (natural) resolution, draws just that region onto a <canvas>, and exports it with canvas.toBlob() in your chosen format.
The cropped result can then be downloaded.

Notes

The selection box is drawn relative to the displayed image size, then scaled up to the image's real resolution — so the crop stays pixel-accurate even if the image is shown smaller than its actual dimensions.
PNG keeps transparency; JPEG fills transparent/cropped-out areas with white.
Nothing is uploaded: cropping happens entirely on your device.
