Why Are Your Images Secretly Slowing Things Down?

Let's be honest - we've all been there. You resize your image to the exact dimensions needed, yet your website still crawls. Here's the thing: size isn't the only speed killer lurking in your images.

Did you know? Even a 1-second delay in page load time can result in a 7% reduction in conversions.

The Invisible Bandwidth Bandits

Your images might be harboring hidden data that's eating up precious loading time:

Unnecessary metadata
Improper file formats
Uncompressed image data

The Three Most Common Image Mistakes

1. Wrong Format for the Wrong Job

Using PNG for photographs when JPEG would do just fine is like using a sledgehammer to hang a picture frame - massive overkill that slows everything down.

2. Skipping Modern Image Formats

WebP and AVIF formats can reduce file size by up to 50% compared to traditional formats, yet many content creators aren't using them.

3. Lazy Loading Gone Wrong

Implementing lazy loading incorrectly can actually hurt your Core Web Vitals scores instead of helping them.
