How it works
Drop any image and enter the width and height you want — the preview updates instantly as you type. Resizing happens entirely in your browser using the Canvas API, so your image is never uploaded anywhere. "Keep proportions" holds your image's original shape: change one dimension and the other follows automatically; switch it off to stretch the image freely. The preset buttons jump straight to half size, quarter size or a common upload width. Downloads keep the original format for PNG, JPEG and WebP images (anything else is saved as PNG).
