An image crop tool lets you remove unwanted portions of a photo while keeping the area you want to highlight. It can be useful for improving composition, removing distractions, or preparing images for social media and websites. Most online cropping tools allow you to select a specific area manually or choose a preset aspect ratio. Before cropping, consider where the image will be used so you can select suitable dimensions. Keeping the original image is also helpful in case you want to create another version later.
