How Image Resizing Works
This tool scales images to custom pixel dimensions entirely within your browser using the HTML5 Canvas API. By checking "Maintain Aspect Ratio", you prevent the image from being stretched or distorted when changing width or height.
Because processing is local, your photos are never sent to a cloud server, ensuring 100% privacy.
