Website performance continues to be one of the strongest factors influencing
user experience and search visibility. Even today, one of the biggest
performance issues on websites is oversized images.
Many developers focus on JavaScript optimization and caching while ignoring
image size, even though images often make up the largest portion of page weight.
How Images Affect Performance
Large images slow down page loading, especially on mobile networks.
This leads to higher bounce rates and weaker engagement signals.
Optimizing images helps with:
- Faster load times
- Better Core Web Vitals
- Improved mobile experience
- Reduced bandwidth usage
Compression Without Quality Loss
Image compression removes unnecessary data while keeping visual quality.
For most websites, lossy compression offers the best balance between size and clarity.
Choosing modern formats like WEBP can further reduce file size without
sacrificing appearance.
A Tool I Use for Quick Optimization
I use a simple browser-based image compressor that runs fully on the client side.
It doesn’t require uploads or accounts and works well for quick optimization.
