Boost WordPress SEO: Why You Must Convert All Images to WebP in 2025
By Image Size Compress Team•
Google has made it clear: Speed is a ranking factor. If your website takes more than 3 seconds to load, you lose 40% of your traffic. The #1 culprit for slow sites is heavy images.
The WebP Advantage
WebP images are 26% smaller than PNGs and 30% smaller than JPGs with zero visible quality loss. This means your site loads faster, your hosting bandwidth usage drops, and Google ranks you higher.
How to Bulk Convert
Don't rely on slow WordPress plugins that bloat your database. Instead, download your media library and run it through our Batch JPG to WebP Converter. Re-upload the optimized files and watch your PageSpeed Insights score turn green.
