Why Compress Images?
Large images are the #1 reason websites load slowly. A 3MB hero image takes 2-3 seconds on 4G. On 3G? 10+ seconds. Most visitors won't wait.
Three problems with large images
- Slow page load times: Google measures Largest Contentful Paint (LCP). Big images = bad LCP = lower rankings.
- Bandwidth waste: A 5MB image uses 5MB of visitor's data plan. Compressing saves them money.
- Storage costs: 1,000 product photos at 3MB each costs more than at 300KB each.
Google's Core Web Vitals
LCP threshold is 2.5 seconds. An unoptimized hero image alone often exceeds that. Compress your images. Your Core Web Vitals improve. Your rankings improve.
Real example: 2,400 x 1,600 JPEG from smartphone = 4-6MB. Compress to 80% quality = 400-800KB. Visually identical. Loading time drops from 3s to 0.4s.
Lossy vs. Lossless Compression: What's the Difference?
Lossy compression
- File size reduction: 70-90%
- Quality loss: Minimal at 70-80%
- Best for: Web images, social media, product photos
- Formats: JPEG, WebP
Lossless compression
- File size reduction: 10-30%
- Quality loss: None
- Best for: Screenshots, logos, graphics with text
- Formats: PNG, GIF
When to Use JPEG vs. PNG vs. WebP
| Use case | Best format | Why |
|---|---|---|
| Product photo on website | WebP > JPEG | Smaller than JPEG, same quality |
| Logo with transparency | WebP > PNG | Smaller than PNG, same quality |
| Screenshot for documentation | PNG | Text stays sharp |
| Email marketing image | JPEG | Email clients support JPEG universally |
| Hero image on blog | WebP with JPEG fallback | Best of both worlds |
