How to Compress Images Without Losing Quality — Complete Guide
Large images are the #1 cause of slow websites. A single unoptimized photo can add 5+ seconds to your page load time. Here's how to compress images properly.
Image Formats Explained
| Format | Best For | Compression |
|---|---|---|
| JPEG | Photos | Lossy — great for photographs |
| PNG | Graphics, screenshots | Lossless — preserves transparency |
| WebP | Everything | Best of both — 30% smaller than JPEG |
| AVIF | Modern browsers | Best compression — 50% smaller than JPEG |
How Much Can You Compress?
Typical compression ratios with VedaWell Image Compressor:
- JPEG photos: 60-80% reduction (5MB → 1MB)
- PNG screenshots: 40-70% reduction (2MB → 600KB)
- WebP: 70-85% reduction
Compression Tips
- Start at 80% quality — visually identical to original for most photos
- Use WebP when possible — supported by 97% of browsers in 2026
- Resize before compressing — a 4000px image displayed at 800px is wasteful
- Batch process — compress all your images at once, not one at a time
