Images are often the largest contributor to slow WordPress websites.
Optimizing images is one of the most effective performance improvements.

Why Images Affect Performance #

Large images:

• Increase page load time
• Consume bandwidth
• Slow down mobile users
• Affect user experience

WordPress does not optimize images automatically by default.

Common Image Optimization Problems #

Typical issues include:

• Uploading original camera images
• Using uncompressed PNG files unnecessarily
• Serving images larger than needed
• Missing responsive image sizes

These issues accumulate quickly.

What Image Optimization Involves #

Image optimization includes:

• Resizing images to correct dimensions
• Compressing images without visible quality loss
• Using appropriate file formats
• Removing unnecessary metadata

This reduces file size significantly.

Image Formats and WordPress #

Common formats:

• JPEG for photos
• PNG for transparency
• WebP for modern optimized delivery

Choosing the correct format matters.

How to Optimize Images #

Images can be optimized by:

• Optimizing before upload
• Using image optimization plugins
• Replacing existing oversized images

Optimization should be ongoing.

What Not to Do #

Avoid:

• Uploading very large images and relying on themes to resize
• Using screenshots for photos
• Ignoring mobile image sizes

These mistakes degrade performance.
