Lossless vs. Lossy Image Compression: Optimizing Web Media for Speed

  <h2>The Heavy Cost of Unoptimized Images</h2>
  <p>Images account for over 60% of the average webpage's total byte weight. Serving raw 5MB PNGs to mobile users on 4G networks destroys page load speed and conversion rates.</p>

  <h3>Choosing the Right Compression Strategy</h3>
  <ul>
    <li><strong>Lossy Compression (WebP / AVIF):</strong> Discards imperceptible high-frequency visual details to slash file size by 70–85%. Ideal for photography.</li>
    <li><strong>Lossless Compression:</strong> Removes redundant metadata, color profiles, and optimizes compression tables without altering a single pixel. Essential for UI screenshots and diagrams.</li>
  </ul>

  <p>Always convert legacy JPEG and PNG formats into modern WebP with responsive srcset attributes.</p>
