AVIF where it saves space
Pro creates AVIF at the same visual quality as WebP and keeps it only when clearly smaller. Savings depend on your images and are often 5–15% across a library, with bigger gains on some photos.

What Pro adds.
Pro adds its features to the same screen as the free plugin. You use the same tabs, the same Save button and one status display.
Built for practical work
Features.
Images sized for each device
Add widths for phones and tablets so browsers can pick a closer fit. This addresses PageSpeed’s “Properly size images” finding.
Learn from real visits
Prioritize the image visitors actually see first to improve Largest Contentful Paint (LCP). This learning uses no cookies or personal data.
Lazy background images
Delay background images farther down the page until visitors need them.
Light video previews
Show a lightweight YouTube or Vimeo preview and load the player on click. Other iframes load lazily.
Smaller animations
Convert animated GIFs to animated WebP to reduce file size while keeping the animation.
Cloud storage and CDN
Serve images, including WebP and AVIF, from Amazon S3, Cloudflare R2, DigitalOcean Spaces, Wasabi, Backblaze B2, another S3-compatible service or a CDN domain. Upload the library in one click, optionally remove local originals, and bring everything back anytime. Your caching plugin still handles CSS, JavaScript and fonts.
Image SEO
Find missing alt text and fill it using smart suggestions. Clean up file names during uploads.
Before and after slider
Compare an original and its optimized version side by side before choosing your settings.
Image Health Report
Scan every page for image problems, fix supported issues in one click and optionally receive a weekly or monthly email report.
More controls for your library
Use blur-up placeholders, WebP for WooCommerce galleries and variations, custom folders, upload size limits and EXIF/GPS removal with backups.
Tools for larger sites
Use WP-CLI, a server-load guard and multisite support. Optimize unlimited images without credits.

A few useful answersGood questions.
Good questions.
Straight answers.
Do I need the free plugin?
Yes. Pro adds settings to Spinix Image Optimization, so keep the free plugin installed and active.
Does it use credits or an external optimization API?
No. Image optimization runs on your server without credits or an image limit. Cloud offload connects to the storage provider you choose.
Will AVIF always be smaller?
Savings vary by image. Pro keeps an AVIF version only when it is clearly smaller than its WebP equivalent.
Does cloud storage offload CSS or JavaScript?
It serves images only. Your caching plugin continues to handle CSS, JavaScript and fonts.
What happens if my yearly licence expires?
Pro keeps working for seven days, then pauses. The free features continue working on your site.
How do I ask about refunds or support?
