Image Optimization

Images often account for most of the downloaded bytes on a webpage. Optimizing them is crucial for faster page loads and better user experience.

Key Optimization Techniques

Choose the right image format:
- JPEG: Best for photographs and complex images with many colors
- PNG: Ideal for images with transparency or text
- WebP: Modern format with superior compression and quality
- SVG: Perfect for logos, icons, and simple graphics
Compress images without quality loss
Use responsive images with srcset
Implement lazy loading
Optimize alt text and filenames

Command Line Image Optimization

# Install ImageMagick
sudo apt-get install imagemagick

# Compress JPEG
convert input.jpg -quality 85 output.jpg

# Compress PNG
pngquant --quality=65-80 input.png

# Convert to WebP
cwebp -q 80 input.jpg -o output.webp

Pro Tips

Use modern image formats like WebP with fallbacks for older browsers
Implement lazy loading using the loading="lazy" attribute
Consider using CSS sprites for small, frequently used images
Use CDN-based image optimization services for automatic optimization

Browser Caching

Proper caching configuration can dramatically improve load times for returning visitors and reduce server load.

Caching Configuration

Apache (.htaccess)

<IfModule mod_expires.c>
    ExpiresActive On
    ExpiresByType image/jpeg "access plus 1 year"
    ExpiresByType image/png "access plus 1 year"
    ExpiresByType image/webp "access plus 1 year"
    ExpiresByType text/css "access plus 1 month"
    ExpiresByType text/javascript "access plus 1 month"
    ExpiresByType application/javascript "access plus 1 month"
    ExpiresByType application/x-font-woff "access plus 1 year"
    ExpiresByType font/woff2 "access plus 1 year"
</IfModule>

Nginx (nginx.conf)

location ~* \.(jpg|jpeg|png|webp|gif|ico|css|js)$ {
    expires 1y;
    add_header Cache-Control "public, no-transform";
}

Caching Best Practices

Use versioning or fingerprinting for cache busting
Implement different cache durations based on content type
Consider using service workers for offline caching
Monitor cache hit ratios

Code Minification

Minification reduces file sizes by removing unnecessary characters without changing functionality.

Minification Tools

# Using npm tools
npm install -g uglify-js
npm install -g clean-css-cli
npm install -g html-minifier

# Minify JavaScript
uglifyjs input.js -o output.min.js

# Minify CSS
cleancss -o output.min.css input.css

# Minify HTML
html-minifier --collapse-whitespace input.html -o output.min.html

Minification Tips

Use source maps in development
Implement automated minification in your build process
Consider using module bundlers like Webpack or Rollup
Keep original files for debugging

Compression Techniques

Enable compression to reduce the size of transmitted data between server and client.

Server Compression Configuration

Nginx

gzip on;
gzip_vary on;
gzip_min_length 1000;
gzip_proxied expired no-cache no-store private auth;
gzip_types text/plain text/css application/json application/javascript text/xml application/xml text/javascript;

Apache

<IfModule mod_deflate.c>
    AddOutputFilterByType DEFLATE text/plain text/html text/xml
    AddOutputFilterByType DEFLATE text/css text/javascript
    AddOutputFilterByType DEFLATE application/xml application/xhtml+xml
    AddOutputFilterByType DEFLATE application/javascript application/x-javascript
    AddOutputFilterByType DEFLATE application/json
</IfModule>

CDN Implementation

Content Delivery Networks improve loading times by serving content from locations closer to users.

CDN Integration Steps

Choose a CDN provider
Configure DNS settings
Update asset URLs
Configure SSL/TLS
Set up caching rules

Example CDN URL Structure

<link rel="stylesheet" href="https://cdn.example.com/css/styles.min.css">
<script src="https://cdn.example.com/js/main.min.js"></script>
<img src="https://cdn.example.com/images/photo.jpg">

Performance Monitoring

Regular monitoring helps identify and fix performance issues before they impact users.

Monitoring Tools

Google PageSpeed Insights
Lighthouse
WebPageTest
GTmetrix

Lighthouse CLI Usage

# Install Lighthouse
npm install -g lighthouse

# Run audit
lighthouse https://example.com --output json --output html --output-path ./report

Mobile Optimization

Mobile optimization is crucial with the majority of web traffic coming from mobile devices.

Mobile-First Strategies

Responsive Design Implementation
Touch-Friendly Interfaces
Mobile-Specific Content
AMP Implementation

Responsive Meta Tag

<meta name="viewport" content="width=device-width, initial-scale=1.0">

Media Queries Example

@media screen and (max-width: 768px) {
    .container {
        width: 100%;
        padding: 0 15px;
    }
}

Server Configuration

Proper server configuration is fundamental for optimal website performance.

Server Optimization Steps

Enable HTTP/2
Configure SSL/TLS
Optimize Database Queries
Implement Server-Side Caching

Nginx HTTP/2 Configuration

server {
    listen 443 ssl http2;
    server_name example.com;
    ssl_certificate /path/to/cert.pem;
    ssl_certificate_key /path/to/key.pem;
}
