How It Works

Your image is loaded into an HTML5 Canvas element, scaled to your chosen dimensions, and re-exported as a new image file — entirely in your browser. No data is ever sent to a server.

Aspect Ratio Lock

When the lock is enabled, changing width will automatically calculate the correct height to maintain the original proportions, and vice versa. Disable it to set independent width and height for a stretched/cropped result.
