Tips for 400x400 Images

Medium images (400×400) are common for web content, blog posts, and email headers. This size balances visual quality with fast page loading.

Web optimization: After resizing, compress your image to reduce file size further. A 400×400 JPEG at 80% quality typically weighs 50-150 KB — well within recommended web performance budgets.

Retina displays: If your image will appear on high-DPI screens, consider exporting at 2× this dimension (800×800) and letting the browser scale it down for sharper rendering.
