What is an image cropper?
This crop image tool lets you cut away the parts of a picture you don’t want and keep just the area you do: upload, drag the selection box to move it and pull the corners to resize, then hit the button to export the cropped PNG or JPG at full resolution. Everything runs locally in your browser — the image is never uploaded.
How to use
- Drag an image into the upload area, or click to choose a file.
- Drag the centre box to reposition it and pull the four corners to resize.
- Pick an output format (PNG / JPG) and click "Crop & download".
Common use cases
- Trim the extra margins or a browser toolbar off a screenshot, keeping only the point.
- Cut a square avatar or the key area of a social cover.
- Want to shrink or convert after? Use compress image or resize image.
Crop, resize, compress — don't mix them up
"The image is too big" means three completely different things, each with its own tool, and confusing them just wastes effort. Cropping cuts away the outer edges, changing the composition and the dimensions — pixels aren't stretched, so if you box only the middle of an 800×600 image the output might be 400×300. Resizing keeps the whole frame and scales the pixels down proportionally, say 4000×3000 to 1200×900. Compressing leaves the dimensions alone and only lowers the file's data (usually by adjusting JPG quality). Want to keep just the point? Crop. Want the same picture in a smaller file? Use resize or compress. Also worth knowing: this tool crops at full resolution, not the thumbnail you see on screen — so boxing a small region still exports crisp native pixels. Only choosing JPG output adds a layer of compression; pick PNG to stay lossless.
