Give one dimension and the other follows from the aspect ratio. Downscaling is done in halving steps, which is what keeps fine detail from breaking up.
How this works
Give a width, a height, or a percentage. With one dimension the other follows from the aspect ratio, which is what people mean by "resize to 800 wide" and never distorts. With both, the fit mode decides: fit keeps the whole image inside the box, fill covers the box and crops the overflow, and exact forces the size and is the only mode that can stretch.
Downscaling is done in halving steps rather than in one jump. A single draw from 4,000 pixels to 300 samples too sparsely and breaks up fine detail; halving repeatedly costs a few milliseconds and is the difference between a thumbnail that looks resized and one that looks broken.
Enlarging beyond the original size is off by default, because it cannot add detail that is not there. Turn it on and the result says it was enlarged, so nobody is surprised by a softer picture.
Website Performance and Core Web Vitals: Why They Matter for Business
Performance is not only a technical topic. Slow pages cost leads, harm SEO, and erode trust, and the things that fix them are usually small, specific, and boringly consistent.

SSR vs CSR vs SSG vs ISR: what to choose for SEO and performance
SSR, CSR, SSG and ISR differ mainly in where and when HTML is generated. For SEO, the key question is whether important content and metadata are available without waiting for client-side JavaScript. For performance, server cost, caching, JavaScript execution, hydration and freshness matter as well. In 2026, the best architecture is usually not one rendering mode for an entire application, but a strategy selected for each route or even each part of a route.

Core Web Vitals in 2026: LCP, INP and CLS in practice
Core Web Vitals in 2026 still consist of three metrics: LCP for loading the main content, INP for interaction responsiveness and CLS for layout stability. The scores alone do not tell you what to fix. Effective optimization requires separating real-user field data from lab tests, finding the actual LCP element, slow interaction or layout shift source, and then monitoring the result after deployment.
