Why Optimize Web Images?
Images make up over 60% of the total page weight on the modern web. Unoptimized images hurt your Google Core Web Vitals (Largest Contentful Paint), increase mobile data usage, and degrade user conversion rates.
By converting legacy JPG and PNG assets into modern WebP or AVIF files and scaling oversized resolution down to web display standards, you can cut image payloads by up to 80% without noticeable quality loss.

Frequently Asked Questions
Should I convert my website images to WebP or AVIF?
WebP is currently the sweet spot with 98%+ global browser support and excellent compression. AVIF delivers even smaller file sizes and is ideal if your audience is primarily on modern desktop and mobile browsers.
What does stripping EXIF metadata do?
EXIF data contains hidden camera settings, device serials, and GPS location coordinates. Stripping this data protects your privacy and removes several kilobytes of unnecessary metadata overhead per image.
