このツールとは？
The image crop tool lets you select a region by pixel (start X/Y and width/height) and save only that part as a new image. Handy for removing borders or extracting a specific area.
なぜ使う？
Useful when you want to remove extra margins, or extract a region for a thumbnail, icon, or profile picture. Processing is done in the browser; files are not stored on the server.
使い方
Upload an image, then set the start X and Y and the width and height in pixels (or use the on-screen controls). Click "Crop" to generate the cropped image and download it as PNG.
The result is saved as PNG. Enter pixel values with the original size and aspect ratio in mind.
