Overview
“Smaller but still sharp” is the goal. True lossless size reduction is limited, but you can make images dramatically lighter without noticeable quality loss by resizing and adjusting compression wisely.
Step-by-step
- Identify the maximum display width your image needs (e.g., 1200px for blog headers).
- Resize to that width while keeping aspect ratio.
- Export as WebP (or JPG) with a sensible quality setting.
Practical tips
- For photos, try WebP or JPG quality around 0.8–0.9 and review visually.
- For UI/graphics, prefer PNG or lossless WebP to preserve crisp edges.
- Don’t scale up small images—upsizing won’t add real detail.
Common presets

FAQ
What’s the fastest way to reduce file size?
Resize to the actual display dimensions first, then choose WebP/JPG with a moderate quality. Visual review beats fixed numbers.
Do I need different sizes for retina displays?
If your site serves 2× assets, export at double the CSS size (e.g., 1600px for an 800px slot) and let responsive images pick the right version.
Will converting PNG photos to JPG reduce size?
Usually, yes—photos compress better with lossy formats. Keep PNG for flat-color graphics and UI.
