How to Compress Images for Better PageSpeed (Without Losing Quality)
Large images can slow down your website, hurt your SEO, and lead to higher bounce rates. Compressing images reduces file size while maintaining quality, helping your site load faster and rank better on search engines.
In this guide, you’ll learn how to compress images properly using both manual methods and automatic tools.
Why Compress Images? (The Benefits of Image Optimization)
✔️ Faster Website Speed – Reduces image load time, improving overall site performance.
✔️ Better SEO Rankings – Google prioritizes fast-loading pages in search results.
✔️ Lower Bounce Rate – Visitors are less likely to leave if your site loads quickly.
✔️ Improved User Experience – Faster images mean smoother browsing on mobile and desktop.
✔️ Reduced Bandwidth Usage – Saves storage space and speeds up server response.
Bottom Line: If your website is slow, image compression is one of the fastest ways to improve PageSpeed.
Step 1: Choose the Right Image Format
Before compressing images, make sure you’re using the right file format.
Best Image Formats for Web:
✔️ JPEG (JPG) – Best for photos and colorful images (small file size, good quality).
✔️ PNG – Best for transparent images, logos, icons (higher quality, larger file size).
✔️ WebP – Best for modern web optimization (smaller file size than JPG/PNG, great quality).
✔️ SVG – Best for logos and icons (scalable without losing quality).
Pro Tip: Use WebP instead of JPEG or PNG for the best balance of quality and compression.
