Speed Up Your Website: The SEO Benefits of Image Compression

Updated: Nov 2025 5 min read

Google has made it clear: page speed is a ranking factor. If your website takes more than 3 seconds to load, 53% of mobile users will abandon it. The #1 culprit? Uncompressed images.

Core Web Vitals and LCP

Largest Contentful Paint (LCP) measures how long it takes for the main content of your page to load. Often, this "main content" is a hero image. If that image is a 4MB raw file, your LCP score tanks, and so does your Google ranking.

Compression = Better User Experience

  • Mobile Users: Many users are on 4G or 5G metered connections. Compressing an image from 2MB to 200KB saves their data and loads your site instantly.
  • Bounce Rate: A faster site keeps users engaged. Lower bounce rates signal to Google that your content is valuable.
  • Server Costs: Smaller files mean less bandwidth usage, which can significantly lower your hosting bills.

How Much Can You Save?

Modern compression (like WebP conversion or aggressive JPG optimization) can often reduce file size by 70-90% with zero visible loss in quality on a standard screen.
