How to Optimize Images for Your Website: Step-by-Step Guide

According to Google, images account for an average of 50–70% of page weight. Image optimization is the simplest way to speed up a site and improve SEO without rewriting code.

Step 1: Choose the Right Format

Different formats are suitable for different types of images:

• JPEG — photos and complex images with gradients
• PNG — images with transparency, screenshots, logos
• WebP — a modern format, 25–35% smaller than JPEG with the same quality
• SVG — icons and simple vector illustrations

Use Image Converter to convert between formats.

Step 2: Resize Before Uploading

Do not upload images at 4000×3000 pixels if it is displayed in an 800px block. Use Image Resizer:

1. Upload the original image
2. Specify the target width in pixels
3. Select "Maintain aspect ratio"
4. Download the result

Step 3: Compress the Images

Image Compressor on Xuvero applies intelligent compression that reduces file size by 30–70% with virtually no quality loss.

Optimal JPEG quality levels: 75–85% for web, 85–95% for portfolios and presentations.

Step 4: Add a Favicon

Don't forget about the favicon — the small icon in the browser tab. Favicon Generator will create a set of icons in all necessary sizes (16×16, 32×32, 192×192, 512×512) from one uploaded image.
