Frequently asked questions
Will resizing blur my image?
Downscaling keeps images sharp — the browser uses high-quality smoothing. Upscaling beyond the original size always costs sharpness, because new pixels must be invented.
How do I keep the proportions right?
Leave the aspect-ratio lock on: type one dimension and the other updates automatically. Unlock it only when you deliberately want to stretch.
What sizes do social platforms want?
Common targets: 1080×1080 (Instagram post), 1200×630 (link previews), 1280×720 (YouTube thumbnail), 1500×500 (X header). Type any of these directly.
