Image Optimization: The Ultimate Website Speed Checklist

Slow image loading is the leading cause of low search rankings and high bounce rates. In the era of Core Web Vitals, image optimization is a necessity. The ARCVOX digital engine has prepared a step-by-step plan to make your visual content fly.

1. Choose the Right Format

Use WebP or AVIF for photographs. They offer up to 50% weight savings over JPG. If you need transparency, converting PNG to WebP preserves the alpha channel while making the file much lighter.

2. Mind the Dimensions

Never upload a 4K photo if it will be displayed in a small block. Perform image resizing to match your UI's real needs. For product catalogs, use bulk resizing to standardize everything in seconds.

3. Strip the Junk

Every image contains hidden headers and metadata. Before publishing, always strip EXIF data. This not only lightens the file but also boosts your project's security.

Verdict: An optimized site means happy users and high rankings. Follow this checklist with ARCVOX tools, and your PageSpeed score will thank you.
