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.
Best Practices
- Hero Images: Typically 1920px or 1600px wide.
- Blog Images: Usually match the content width (e.g., 800px or 1000px).
- Thumbnails: Keep them small (e.g., 300px or 400px).
