How to Resize Images for the Web

By VexDocs Team Updated Dec 2025

Images that are too large slow down your website and hurt your SEO. Resizing them to the correct dimensions is a quick win for performance.

Why Resize?

If your website displays an image at 800px width, but the file is 4000px wide, the browser has to download unnecessary data and then shrink it. This wastes bandwidth and battery.
