How it works
This tool lets you visually select part of an image and keep only that region. After you drag a crop box, the selected rectangle is copied into a new canvas and becomes the current image. Cropping changes image dimensions because unused outer areas are removed.
- Selection: drag across the image to choose the area you want to keep
- Validation: very small selections are ignored to prevent accidental crops
- Result interpretation: the cropped size tells you how much of the original image remains after trimming
- Best use: cropping is ideal when you want to remove empty margins, isolate a subject, or prepare a cleaner image for sharing
Examples
- Screenshot cleanup: remove browser chrome, blank edges, or unrelated interface elements
- Product image: crop tightly around an item to make the subject more prominent
- Thumbnail preparation: trim extra space so the main subject fills more of the frame
- Profile or avatar image: isolate the face or central subject before further editing

FAQ
- How do I crop an image?
Upload an image, drag on the preview to select an area, then click Crop Image. The selected region becomes the new cropped result.
- Is my image uploaded?
No. Everything runs locally in your browser and the image is not uploaded by this tool.
- Does cropping reduce image quality?
Cropping removes unwanted areas but does not automatically reduce image quality. The cropped result keeps the selected pixels from the original canvas.
- Can I crop multiple times?
Yes. After cropping, you can continue selecting a new area and crop again, or reload the original image.
- Why is my selection invalid?
Selections that are too small are rejected because they are usually accidental drags and do not produce a practical crop area.
- What is this tool useful for?
It is useful for trimming screenshots, removing empty edges, focusing on a subject, preparing thumbnails, and cleaning up product or profile images.
