The problem
Every time you upload a photo from your phone to WordPress, you might add a 3–8 MB file. Multiply that across blog posts and product pages — your site becomes slow.
Solutions
1. Compress before upload — drag images into OptimizeImage first. 2. Limit max upload dimensions — 1920px wide is enough for most screens. 3. Use a CDN — Cloudflare caches optimized assets globally. 4. Enable lazy loading — WordPress 5.5+ does this by default. 5. Audit media library — replace the largest files first.
Result
Most WordPress owners see 30–70% faster page loads after compressing their heaviest images. Better speed = better SEO and more sales.
