How to use the Image Cropper
- Drop or select an image.
- Draw a selection with the mouse, or enter the crop coordinates manually (X, Y, Width, Height in pixels).
- Choose the output format and click Crop & Download.
Coordinate system
Coordinates are measured from the top-left corner of the image:
- X: horizontal distance from the left edge in pixels
- Y: vertical distance from the top edge in pixels
- Width: width of the cropped region in pixels
- Height: height of the cropped region in pixels
Example: to crop a 200×200 region starting 100 pixels from the left and 50 pixels from the top, set X=100, Y=50, W=200, H=200.
Common use cases
- Profile pictures: crop a photo to a square before uploading as an avatar
- Removing unwanted elements: cut out borders, watermarks, or distracting backgrounds
- Creating thumbnails: extract the most important part of a larger image
- Social media crops: prepare images at platform-specific aspect ratios (1:1 Instagram, 16:9 Twitter/X, 1.91:1 OG image)
- Extracting details: zoom into a specific region of a document or photograph
