Why Keep the Aspect Ratio?
An image's aspect ratio describes the relationship between its width and height. Keeping the aspect ratio locked helps prevent the image from appearing stretched or squashed after resizing.

Image resizing is performed locally in your browser using the HTML Canvas API. The selected image does not need to be uploaded to ATBot's server.
