Why Compress Images?
Large images slow down your website, increase bandwidth costs, and frustrate users. Google considers page speed a ranking factor β a 1-second delay can reduce conversions by 7%.
Understanding Image Compression
Lossy vs Lossless
Lossy compression permanently removes data to reduce file size. JPEG is the most common lossy format. Lossless compression reduces file size without losing any data. PNG uses lossless compression.Format Comparison
| Format | Compression | Transparency | Best For |
| JPEG | Lossy | No | Photos |
| PNG | Lossless | Yes | Graphics, logos |
| WebP | Both | Yes | Modern web |
| AVIF | Both | Yes | Next-gen |
Best Practices
- Choose the right format β JPEG for photos, PNG for graphics with text
- Resize before compressing β don't upload a 4000px image for a 400px display
- Use 75-85% quality for JPEG β the sweet spot between size and quality
- Strip EXIF data β removes metadata like GPS coordinates and camera info
- Use progressive JPEGs β they load gradually, improving perceived speed
