Overview

Why 1080×1080?

1080×1080 pixels is Instagram's standard square post size — the dimension the app itself displays feeds and grids at, so posting at this exact size avoids any extra compression or re-cropping. Every image uploaded here is redrawn onto a canvas at exactly 1080×1080, 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.
