Overview
What Is the Crop Image Tool?
Crop Image is a browser-based tool for removing unwanted edges and focusing attention on the most important part of a picture. The interactive Image Cropper lets you drag and resize the selection directly over your photo, while exact width, height, X, and Y controls provide pixel-level placement when a precise layout matters.

Tips
Tips for a Better Photo Crop
Keep faces, text, and important objects comfortably inside the crop boundary. Use the rule-of-thirds guide to position the main subject, choose an aspect ratio that matches the final placement, and begin with the highest-resolution source available so the cropped result keeps as much detail as possible.
Crop Image FAQ
Can I choose an exact crop size and position?
Yes. Enter the crop width and height in pixels, then use the X and Y fields to control its position from the image’s top-left corner. The preview updates as the values change.
Can I move and resize the crop area directly on the image?
Yes. Drag inside the selection to move it. Drag the handle at its lower-right corner to change its size. The form values stay synchronized with the preview.
Does cropping reduce image quality?
Cropping removes pixels outside the selected area but does not enlarge the pixels that remain. PNG uses lossless output, while JPG and WebP quality can be adjusted before export.
Is it safe to crop a picture online here?
The selected picture is processed locally in your browser. It is not uploaded to or stored on an imglab server.
Which crop ratio should I choose?
Use 1:1 for square images, 16:9 for widescreen visuals, and 4:3 or 3:2 for common photo layouts. Choose Free when the final frame does not need a fixed ratio.
