Image size directly affects load time and SEO rankings. Learn how to compress and optimize images using native PHP functions. This guide is perfect for blogs, e-commerce platforms, and developers aiming to improve speed without compromising quality.

🔥 Why Image Compression in PHP?

• Improves page load speed (critical for user experience)
• Boosts SEO (Google ranks fast-loading sites higher)
• Reduces bandwidth usage

🔧 Basic PHP Image Compression Code

function compressImage($source, $destination, $quality) {
  $info = getimagesize($source);

  if ($info['mime'] == 'image/jpeg')
    $image = imagecreatefromjpeg($source);
  elseif ($info['mime'] == 'image/png') {
    $image = imagecreatefrompng($source);
    imagealphablending($image, true);
    imagesavealpha($image, true);
  }

  imagejpeg($image, $destination, $quality);
  return $destination;
}

💥 Common Errors & Fixes

• Error: "Undefined function imagecreatefromjpeg()"
  Fix: Enable GD extension in your php.ini.
• Error: Image quality not changing
  Fix: Adjust quality value (0–100). Lower = more compression.
• Error: Transparent PNG becomes black
  Fix: Use imagesavealpha() to preserve transparency.

✅ Best Practices & Precautions

• Back up original images before compression
• Use different quality levels for thumbnails, product images, and banners
• Combine with lazy loading and WebP conversion for performance boost

💰 Monetization & SEO Tips

• Target high-paying keywords like “image optimizer”, “site speed tools”, etc.
