Image sizing is one of the simplest speed wins

Resizing images before publishing keeps the browser from downloading pixels the visitor will never see. A homepage hero, portfolio card, blog image, and social preview all need different dimensions. Good sizing protects quality while reducing page weight, especially on mobile. For search performance, resizing works best alongside descriptive filenames, useful alt text, modern formats, and compression that matches the image's role on the page.

Match image dimensions to the largest real display size in the layout.
Create smaller assets for cards, thumbnails, and below-the-fold sections.
Resize before compression so the final file is both clean and lightweight.
