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. The aspect-ratio lock keeps your image's original proportions: change one dimension and the other follows automatically; switch it off to stretch the image freely. Downloads keep the original format for PNG, JPEG and WebP images (anything else is saved as PNG).
