Crop to a ratio, rotate by 90 degrees, flip, and save as PNG, JPG or WebP.
Choose an image to start cropping.
Drag the box or its handles. Arrow keys move it, Shift with arrows resizes it.
Aspect ratio
It cuts a rectangle out of a picture, turns the picture by quarter turns or mirrors it, and saves the result as PNG, JPG or WebP. The picture is opened and processed inside your browser, so a private photo is never uploaded, and a large photo does not wait in any queue.
Dragging works with a mouse, a finger or a pen. For precise work the four number fields give the left edge, the top edge, the width and the height in pixels, and the arrow keys move the box when it has the focus, with Shift and the arrows resizing it. Nothing in the tool needs a pointer.
A worked example: a 4000 by 3000 photo is 4:3. The largest centred 16:9 crop is 4000 by 2250 pixels, starting 375 pixels from the top. The largest centred square is 3000 by 3000, starting 500 pixels from the left. Choose a ratio first, then move the box to the part you want to keep.
The buttons turn the picture by 90 degrees to the left or right, and mirror it horizontally or vertically. The crop box travels with the picture, so it keeps covering the same part of it. Mirroring is useful for a selfie that was saved the wrong way round, and turning is useful for a scan that came in sideways. All of it is exact: a quarter turn only moves pixels, it does not blur them.
PNG keeps every pixel and any transparency, which suits graphics and screenshots. JPG is smaller for photographs and has no transparency, so the tool fills it with white. WebP is smaller than both, keeps transparency and is read by every current browser. For JPG and WebP the quality slider trades size for fidelity; around 80 to 92 is a sensible range.
Photos that carry an orientation tag, as phone cameras do, are shown upright. The saved file contains only pixels: the location, the camera and the other metadata stored in the original are not copied. A very large picture is limited to about 50 million pixels, because that is what browsers can handle safely.
No. The image is opened and cut in your browser and the result is created on your device. Nothing is sent over the network.
Not for PNG: every pixel in the area is kept as it is. JPG and WebP are compressed again when saved, so use a high quality setting if you need the best fidelity.
Set the crop with the Width and Height fields, and the Left and Top fields for its position. With a ratio selected, changing the width changes the height to match.
No. The file is created from the pixels only, so GPS position, camera model and other metadata are not copied.
Yes. Drag the box and its handles with a finger, or type the numbers. The page scrolls normally everywhere except on the box and its handles.
