Smaller images, faster pages
What it does.
Compress images in WordPress and serve them as WebP. Spinix also helps the main image load sooner and reserves space for images to reduce layout shift.

Built for practical work
Features.
Automatic WebP for new uploads
Convert new images to WebP as you upload them, including every generated size.
Choose your compression
Pick Smart, Smallest files or Best quality, or use PageSpeed-safe compression.
Safe WebP delivery
Use the <picture> tag with automatic fallback or swap the image URL directly. Works with page caches and CDNs.
WebP for backgrounds
Serve WebP for inline CSS background images, including those from page builders such as Elementor.
Smart lazy loading
Load images farther down the page when needed and keep the first images loading normally.
Hero image priority
Give the main image fetchpriority to help it appear sooner. Let Spinix choose or select the hero in the page editor.
Prevent image layout shifts
Add missing width and height so the browser can reserve space before an image loads.
Keep your originals
Original files stay intact. Serve the original, retry a failed image or optimize it again in one click.
