Image optimization for WordPress blogs (quality without slow pages)

Images improve readability and trust, but they can also be the biggest reason a page feels slow.

Start with the right dimensions

Don’t upload huge images “just in case.”

• Use the maximum size you actually display.
• Prefer responsive sizes when possible.

Use modern formats when appropriate

• WebP is often smaller than JPEG/PNG.
• Keep PNG for images that truly need transparency.

Compress before upload

Compression usually has a bigger impact than any plugin.

A simple rule:

• photographs: moderate compression
• screenshots: optimize carefully to keep text readable

Avoid layout shift

Layout shift happens when the page loads and elements move.

• Reserve space for images.
• Don’t insert large images above the fold without planning.

Don’t overdo it

Your job is to be clear, not cinematic. A few helpful images beat dozens of decorative ones.

Fast pages feel trustworthy, and that helps every part of your blog—SEO, engagement, and monetization.
