Pixellize Image Optimizer is a fast, lightweight, and beginner-friendly WordPress plugin that automatically converts uploaded images into modern WebP format.
It ensures that your website loads faster by replacing original image URLs across your entire site — including post content, image tags, and responsive srcset.
⚡ No manual conversion. No complex setup. Just upload and optimize.

✅ Adjustable WebP quality (0–100, default: 85)
✅ Optional maximum image dimension to scale down large uploads before conversion

Attachment tags
srcset (responsive images)
Post/page content
