What size should website images be?

It depends on use: hero images 1920px wide (max 200 KB), blog content images 1200px wide (max 150 KB), product thumbnails 600px wide (max 80 KB), avatars 200px (max 30 KB). Always pair resizing with compression for best results.

Does image size affect Google rankings?

Yes. Google uses Core Web Vitals including LCP (Largest Contentful Paint) as a ranking signal. Large, unoptimised images are the most common cause of poor LCP scores, which can directly hurt your search rankings.

What is the best image size for a blog post?

1200px wide is the practical maximum for blog post content images. Most blog layouts are narrower than this. Setting the width to 1200px and compressing to WebP at 80% quality typically gives files under 150 KB.

How do I resize images for a WordPress website?

FileCrisp resizes images in your browser before you upload them to WordPress. Resize to your theme's content width (usually 1200px), compress to WebP, then upload. This bypasses WordPress's sometimes inconsistent auto-resize.
