How to crop part of an image in your browser
Sometimes you only need one piece of a picture: a face from a group photo, a section of a screenshot, or a product without the clutter around it. This crop tool shows your image on the page with a dashed selection box that you drag over the part you want, then saves just that part as a separate image.
Cropping happens inside your browser, and the selected area is cut from the original full-resolution image rather than from the small preview, so the result keeps the original quality.
How to use it
- Drag an image onto the upload box or click it to choose a file. A preview appears straight away, up to 480 pixels wide.
- A semi-transparent dashed rectangle appears on top, covering half the image width and half its height.
- Click and drag the rectangle with your mouse to the area you need. It stays inside the image edges.
- Click Crop & download. The selected area downloads as cropped.png and a confirmation message appears.
Features
- Live preview: you see exactly where the selection sits before cutting.
- Full resolution: the box position is mapped back to the original image, so the crop has the real pixel count.
- PNG output: no extra compression loss, and transparency is preserved if the source had it.
- Repeat crops: move the box and click the button again to extract another area from the same image.
Practical uses
- Pulling one quarter of a chart or table out of a screenshot to share in a chat.
- Isolating a product in the middle of a wide shot before uploading it to a store.
- Trimming unwanted edges from a photo.
- Cutting a large image into several sections by moving the box and cropping more than once.
Tips and notes
- The selection size is fixed: the box always covers half the width and half the height; you control its position. For a smaller area, crop once, then crop the result again.
- Best on a computer: moving the box relies on mouse dragging, so it is easier on a desktop than on a touch screen.
- File size: PNG files are larger than JPG for photos, so convert the result to JPG afterwards if you need a lighter file.
- All processing is local; the image is not uploaded anywhere.
For a round profile picture try Circle crop image, to cut an image into an even grid use Split image, and to set the final dimensions after cropping use Resize image.
