Crop Image — Cut to Exact Pixel Coordinates

Remove unwanted areas from any image by specifying exact crop coordinates. Enter the X and Y position of the top-left corner, plus the width and height of the crop area. Toggle aspect ratio lock to constrain the proportions. The output is saved in the same format as the input — crop a JPEG and download a JPEG. Everything runs in your browser with no file upload.

How to use this tool

  1. Upload your image

    Drop a JPEG, PNG, WebP, or AVIF image. The original dimensions are shown so you can plan your crop coordinates.

  2. Enter crop coordinates

    Set the Left (X) and Top (Y) position of the crop start point, plus the Width and Height of the area to keep. All values are in pixels measured from the top-left corner of the original image.

  3. Enable aspect lock (optional)

    Toggle Aspect Locked to maintain the original aspect ratio when you adjust width or height. Useful for profile pictures or thumbnails with specific dimension requirements.

  4. Crop and download

    Click Crop Image to preview the result. If it looks right, click Download to save the cropped file.

Frequently Asked Questions

How do I find the crop coordinates I need?

Open the original image in any image viewer and hover over the point where you want the crop to start. Most viewers show pixel coordinates in the status bar (bottom of the window). Note the X (horizontal) and Y (vertical) values. Then estimate the width and height of the area to keep, and enter those values into this tool.

Does cropping reduce image quality?

No. Cropping only removes pixels around the edges — the pixels you keep are identical to the originals. The remaining area is saved at the same quality level. This is different from resizing, which changes the pixel density of the entire image.

Can I crop a circle or non-rectangular shape?

This tool crops to rectangles only, which is the most common need. For circular crops, circle masks, or custom shapes, you need an image editor like Photoshop, GIMP (free), or Canva.

What if I enter crop values larger than the image?

The crop area is automatically clamped to the image boundaries. For example, if the image is 1000×600 and you enter a width of 1200, the tool will use 1000 as the maximum. The resulting crop will be 1000 pixels wide rather than throwing an error.

Can I crop multiple images at once?

This tool works one image at a time since each image requires individual coordinate input. For batch cropping to consistent dimensions (like creating consistent social media thumbnails), a design tool like Figma or Canva with batch export is more appropriate.
