Convert PNG & JPG to WebP Format Locally
ImageHob converts JPEG and PNG images into next-generation WebP format entirely inside your browser with zero server uploads. Switching to WebP reduces image payload sizes by an average of 32% compared to JPEG and 68% compared to PNG, directly improving Google Core Web Vitals and Largest Contentful Paint (LCP).
Why does converting images to WebP improve SEO and Core Web Vitals?
Google PageSpeed Insights explicitly recommends next-gen WebP images because smaller image payloads directly accelerate Largest Contentful Paint (LCP), a confirmed Google Search ranking factor.
How do I batch convert PNG and JPG files to WebP privately?
Drag and drop your entire folder of PNG or JPG assets into ImageHob; the output format is pre-set to WebP so you can export all converted files with a single click.
