WHY UPGRADE
Robin Free handles the essentials, while Pro removes the remaining bottlenecks
Robin Free optimizes images automatically. Robin Pro focuses on deeper performance gains where it matters most.
Automatic image optimization
Robin Free compresses images on upload and serves WebP to supported browsers while preserving visual quality.
Modern formats unlock better efficiency
WebP is effective, but larger images and key pages benefit from newer formats like AVIF and performance-tuned compression.
Performance-focused optimization
Robin Pro adds AVIF support and PageSpeed-oriented compression modes designed for faster real-world results.
HOW PRO GOES FURTHER
Optimization designed for real-world performance
Robin Free handles automatic optimization. Robin Pro focuses on deeper performance gains using next-gen formats and performance-tuned compression.
More efficient image formats
WebP is available in Free. Robin Pro adds AVIF support for higher compression efficiency on large and high-impact images, with safe fallbacks for unsupported browsers.
Compression tuned for performance
Robin Pro includes PageSpeed-focused compression options designed to improve loading performance on image-heavy and high-impact pages.
Automatic optimization
Images are optimized automatically in the background, so your workflow stays unchanged as you upgrade to Pro.

FORMAT COMPARISON
Serve the best image format, automatically
Robin automatically serves the most efficient image format supported by each browser, with safe fallbacks when needed. Robin Pro extends this with AVIF for even better efficiency on large and high-impact images.
JPEG & PNG
Legacy formats
Less efficient by today’s standards
Reliable and widely supported formats, but they typically produce larger image files than newer alternatives. This increases page weight on image-heavy pages.
WebP
FREE
Modern default | Unlimited in Free
Designed for efficient delivery
Produces smaller image files than JPEG and PNG while maintaining visual quality. A practical performance improvement with broad browser support.
AVIF
PRO
Advanced format | Unlimited AVIF conversion in Pro
Maximum efficiency for large images
Delivers smaller file sizes than WebP, with the biggest gains on large, hero, and high-resolution visuals. Robin Pro includes unlimited AVIF conversion, making it ideal for image-heavy pages where reducing page weight matters, with safe fallbacks for unsupported browsers.

Every day, images across posts and pages

Frequently asked questions
Will upgrading affect existing images?
No. Upgrading to Robin Pro does not change or reprocess your existing images automatically. You stay in full control, Pro features apply only when you choose to use them, such as enabling AVIF.
How many images can I optimize with each plan?
There’s no hard limit on the number of images you can optimize. All plans allow unlimited image optimization across the number of sites included in your license.
Can I use Robin Image Optimizer on client sites?
Yes. The Agency plan is designed for client work and allows you to use Robin on client websites within your licensed site limit. You can manage and optimize images across all client sites from a single license.
Why do I have to pay for the plugin every year?
Your license helps us continuously improve Robin with new features, performance updates, security fixes, and compatibility with the latest WordPress versions, plus ongoing support when you need it.
How does Robin optimize images without losing quality?
Robin intelligently analyzes each image and applies smart compression to reduce file size while preserving visual quality. The result is smaller images that still look sharp and natural.
Is it possible for a group to buy one shared license?
Licenses are intended for a single owner or organization and shouldn’t be shared across unrelated users. If you manage multiple sites or clients, our Agency plan is the best fit.
Can I downgrade later?
Yes. You can downgrade or stop renewing your Pro plan at any time.
Your existing optimized images will remain untouched, and Robin will continue working with the features available in the Free version.
