Overview

Why 512×512?

512×512 is a common square size for app icons, source favicon artwork, and the resolution many AI image generators output by default. Every image uploaded here is redrawn onto a canvas at exactly 512×512, stretched to fill the square if its original proportions differ.

Why this runs entirely in your browser

Resizing uses the browser's own Canvas API to redraw the image at the new dimensions locally, so the original file never leaves the device — no upload, no server-side processing.

Common uses

Preparing an image for a specific platform's exact size requirement, shrinking a photo to fit a website's max width, or scaling a batch of screenshots down for a document.
