Introduction
Slow image loading is a common issue for websites. A structured workflow helps you diagnose and fix it fast.
Step 1: Diagnose
Use PageSpeed Insights and check image recommendations. As a rule of thumb, keep most web images under 200KB.
Step 2: Identify root causes
| Issue | How to detect |
|---|---|
| Uncompressed assets | Large file size |
| Wrong format | PNG used for photos |
| Oversized dimensions | Rendered size much smaller than source |
| Too many heavy images | One page has many large files |
Step 3: Apply fixes
- Compress images.
- Convert to WebP when suitable.
- Enable lazy loading.
- Use CDN delivery.
