Compress images for the web

Every kilobyte matters on the web. A page with 2 MB of images takes 4 seconds to load on a 4G connection. Compress your images to under 200 KB each and watch your page speed score jump.

Why it matters

Web images need compression

Page speed = search ranking

Google uses page speed as a ranking factor. Sites with optimized images score higher on PageSpeed Insights and rank better in search results.

User experience on mobile

Mobile users on 4G or slower connections feel every extra kilobyte. Compressed images load faster and reduce bounce rates.

Bandwidth costs add up

For sites serving millions of images per month, each kilobyte saved per image translates to meaningful CDN cost reductions.

FAQ

Common questions

What quality level should I use for web images?

Quality 78-82 is ideal for most web images. This range reduces file size by 50-70% while keeping quality visually identical to the original.

Should I convert to WebP before compressing?

Yes. Converting to WebP and compressing in one step gives the best results. WebP compression is more efficient than JPG, so you get smaller files at the same quality.

How does image compression affect Core Web Vitals?

Smaller images improve Largest Contentful Paint (LCP), the most important Core Web Vital for images. They also reduce Cumulative Layout Shift (CLS) because they load faster and trigger fewer layout shifts.
