Your website is slow because your images are too big. A single uncompressed photo can be 5-10 MB. Multiply that by 10 images per page and you're asking visitors to download 50-100 MB just to see your homepage. Most will leave before it loads.
The 80% Rule
You can reduce most images by 60-80% with zero visible quality loss. The human eye can't tell the difference between a 5 MB original and a 1 MB compressed version. But your website load time can tell the difference.
How to Compress Without Quality Loss
- Open the Image Compressor
- Drop your images in (supports JPG, PNG, WebP)
- Set quality to 80-85% (the sweet spot for web)
- Download the compressed versions
Target File Sizes
For a fast website, aim for these sizes:
- Hero images: Under 200 KB
- Blog post images: Under 100 KB
- Thumbnails: Under 30 KB
- Icons/logos: Under 10 KB (use SVG when possible)
Why This Matters for SEO
Google uses page speed as a ranking factor. Core Web Vitals, specifically Largest Contentful Paint (LCP), directly measures how fast your main content loads. Large images are the #1 cause of poor LCP scores. Compress your images and your Google rankings improve. It's that direct.
