How do I crop an image to a specific aspect ratio?

Upload your image, then click one of the preset aspect ratio buttons (1:1, 4:3, 16:9, 3:2) or select Custom to enter your own width and height values. The crop overlay will update instantly.

What image formats are supported for cropping?

GoToolly's image cropper supports JPG, PNG, and WebP formats. All processing happens in your browser, so any image your browser can display can be cropped.

Is my image uploaded to a server?

No. All cropping is performed entirely in your browser using the HTML5 Canvas API. Your images never leave your device.

Can I crop a portion of an image by pixel coordinates?

Yes. After uploading, you can enter exact X and Y coordinates along with width and height values in pixels to crop a precise region of the image.

Does cropping reduce image quality?

No. Cropping simply selects a portion of the original image. The cropped area retains its original resolution and quality. PNG images are preserved losslessly.
