QuickWebP helps you optimize images in WordPress as soon as they are uploaded. It converts JPG and PNG files to WebP, compresses them locally without any external API, cleans filenames for better image SEO, pre-fills media metadata, and resizes oversized uploads automatically.
If you want even smaller next-generation images, QuickWebP Pro adds AVIF conversion for supported servers. It is designed for faster pages, better Core Web Vitals, and a simpler image workflow inside the WordPress media library.
