Pro WordPress caching and optimisation
Turbo Charge Your WordPress Website
Holographic Extreme Cache Pro gives WordPress site owners a smarter performance toolkit: static page caching, intelligent cache clearing, preload, Cloudflare, CDN rewriting, image optimisation, safe asset controls, database cleanup and reporting.
Start with the free cache engine, then upgrade to Pro when you want better speed controls, clean diagnostics and practical tools that help you optimise the site without guessing.
The Free Plugin Gives You Cache. Pro Gives You Control.
Basic caching can help, but real WordPress performance work usually needs more than one on/off switch. Pro adds smarter clearing, safer testing tools, modern image delivery, Cloudflare support and clearer status information so you can improve speed without losing track of what the plugin is doing.
Spend Less Time Guessing
Use diagnostics, cache checks, reports and clearer status panels to see what is working instead of relying on trial and error.
Avoid Heavy-Handed Purges
Advanced smart purge helps refresh related URLs without treating every small content change as a reason to throw away the whole cache.
Modernise Images Safely
Convert JPEG and PNG images to WebP or AVIF where supported, keep the originals as fallback files, and use modern page code for compatible browsers.
A Practical Performance Upgrade For Serious WordPress Sites
Holographic Extreme Cache Pro is built around the performance areas that matter most on real WordPress sites: reliable page caching, safer optimisation controls, image optimisation, Critical CSS, smart cache rebuilding, WooCommerce awareness, CDN support, diagnostics and rollback tools.
Everything You Need To Optimise With More Confidence
Pro puts the highest-impact features first: keep pages cached, protect sensitive pages, reduce image weight, improve above-the-fold rendering, then tune CSS, JavaScript, fonts, CDN and database cleanup. The aim is not to switch everything on at once. The aim is to improve speed in the right order without breaking checkout pages, forms, menus, images or scripts.
- Page cache foundation: Static HTML caching remains the centre of the plugin, with Pro controls built around it.
- Safe Mode: Disable risky Pro optimisation while keeping page cache active.
- Per-page optimisation profiles: Apply safer optimisation rules to checkout, account, contact and other sensitive pages.
- WooCommerce-aware diagnostics: Check cart fragments, checkout rules, cart cookies, product archives and shop-related cache safety.
- Checkout-safe handling: Help protect cart, checkout, account, order and payment pages from risky optimisation.
- Advanced exclusions: Exclude by URL, cookie, query string, role, post type, taxonomy and user agent.
- Plugin conflict checks: Detect other cache, CDN, image and optimisation plugins that may overlap with Pro.
- On-server image conversion: Convert supported images locally on the site's own hosting, with no external credit packs, conversion tokens or per-image charges.
- WebP upload conversion: Create modern WebP versions while keeping the original JPEG and PNG files.
- AVIF upload conversion: Use AVIF where the hosting environment supports it reliably.
- Existing image scan: Show counts for JPEG, PNG, WebP, AVIF and skipped files before processing older media.
- Background batch conversion: Convert older Media Library images gradually through a safer background queue.
- Modern image output: Use picture/source markup with original image fallback.
- Image conversion reports: See what has processed, failed or been skipped.
- Lazy loading: Reduce initial page weight for images, iframes and YouTube embeds.
- Critical CSS: Generate above-the-fold CSS for supported pages.
- CSS minification: Reduce stylesheet size before delivery.
- JavaScript defer: Improve script loading without delaying every script blindly.
- JavaScript delay: Test more aggressive script loading rules on suitable pages only.
- Local Google Fonts: Reduce reliance on external font requests where suitable.
- Font preload controls: Prioritise important font files used early in the page load.
- Advanced smart purge: Refresh related posts, pages, archives, products, taxonomies, parent pages and connected listing pages.
- Related URL preview: See which URLs Pro expects to clear before relying on a wider cache purge.
- Sitemap preload: Rebuild cached pages from sitemap URLs after cache clearing.
- Priority preload queue: Give important URLs faster attention after a purge.
- Homepage and menu warming: Prioritise homepage links, menu links, recent content and high-value pages.
- Controlled cache warming: Rebuild larger sites gradually so preload does not hammer the server.
- Cloudflare cache purging: Clear Cloudflare alongside the local WordPress page cache.
- Simpler Cloudflare setup: Connect by domain without manually entering a Cloudflare Zone ID.
- CDN URL rewriting: Serve static assets through a separate CDN hostname when required.
- Redis checks: Detect object-cache availability and show useful server-cache guidance.
- Server cache helper tools: Provide safer setup checks where the host allows server cache integration.
- Database cleanup: Remove common WordPress clutter with backup prompts and safer cleanup limits.
- Cache speed checks: Compare uncached and cached responses from inside the plugin.
- Performance reports: Review cache status, optimisation results and speed changes more clearly.
- Before and after checks: Compare optimisation changes before relying on them.
- Rollback tools: Reverse optimisation changes more safely if a setting causes problems.
What You Actually Get From Pro
The point of Pro is not to add a huge settings screen for the sake of it. It is to help you keep more pages cached, serve lighter assets, understand what is happening, and avoid common optimisation mistakes.
Smarter Cache Refreshing
When content changes, Pro can consider related URLs such as the post, homepage, archives, taxonomy pages, author pages, parent pages and WooCommerce shop/category pages.
Faster Warm Cache Recovery
Priority preload and sitemap preload help important pages get rebuilt after cache clearing, rather than leaving key URLs uncached until visitors hit them.
Cloudflare Working With WordPress
Connect Cloudflare with an API token and domain name, then let Pro handle cache purging without asking users to hunt for technical IDs.
Safer Compatibility Rules
Exclude pages and requests by URL, cookie, query string, user role, post type, taxonomy or user agent for safer compatibility with dynamic areas.
Lighter Image Delivery
Convert JPEG and PNG uploads to WebP or AVIF where supported, then serve modern image sources while keeping the original file as a fallback.
Better Asset Loading
Improve frontend loading with local Google Fonts, font preload, CSS minification and controlled JavaScript defer or delay options.
Old Images Can Be Upgraded
Scan older Media Library images, show what will be processed or skipped, and run slow background conversion without keeping the admin page open.
Know When To Stop
Use reports, speed checks and rollback tools to test changes carefully instead of stacking optimisation settings until something breaks.
One Licence, Full Feature Set
Every licence tier includes all Pro features. Choose the tier based on how many sites you need to activate, not which tools you want unlocked.
Modern Image Formats Without Replacing Originals
Large images are one of the most common reasons WordPress pages feel heavy. Pro can create modern image versions on the same server, where the hosting environment supports the required image tools. WebP is the safest recommended default for most sites. AVIF can produce smaller files on some sites, but it is more dependent on server support and may take longer to convert.
WebP Recommended
WebP is the safest modern-image option for most WordPress sites. It is widely supported, usually converts faster than AVIF, and is a sensible default for shared hosting.
AVIF Advanced
AVIF can create smaller files, especially for photographs, but it depends more heavily on the host’s image library and can be slower to generate.
Background Conversion
Existing images can be scanned and converted slowly in the background. Users can leave the admin page while WordPress cron continues the queue.
Why This Helps Sales Pages, Blogs And Portfolio Sites
Modern image formats can reduce image weight while keeping visual quality acceptable. That can help pages feel faster, especially on image-heavy websites such as service pages, portfolios, galleries, blogs and WooCommerce content.
The original JPEG or PNG remains in place, so the site keeps a safe fallback while modern browsers can receive WebP or AVIF sources.
Why The Scan Count Looks Higher
A WordPress Media Library item is not always just one physical file. WordPress may create thumbnail, medium, large and other resized versions. Pro counts the physical JPEG and PNG files because each size may need its own matching WebP or AVIF version.
Existing WebP and AVIF files are skipped. Unsupported files such as SVG, PDF and GIF are not processed by the modern image converter.
Performance Tools That Respect Real Websites
A speed plugin is only useful if the site still works afterwards. Holographic Extreme Cache Pro is built around safer defaults, clearer help text and controls that explain what each feature does before you turn it on.
Recommended Safe Setup
Start with page cache, smart purge, safe exclusions and preload. Then add WebP image conversion, Cloudflare, CDN, lazy loading, local fonts and asset optimisation only where the site needs them.
Not every feature should be enabled on every website. The best setup is the one that improves speed without breaking menus, forms, checkout pages, sliders, tracking scripts, image layouts or logged-in areas.

Before You Buy
What do I get when I buy Pro?
You get the full Holographic Extreme Cache Pro feature set, including smarter cache clearing, advanced preload, Cloudflare support, CDN rewriting, modern image conversion, optimisation tools, reports, rollback support and safer controls for testing performance changes.
Which licence do I need?
Choose the licence based on how many WordPress sites you want to activate. Every licence tier includes the same Pro features, so you are not forced into a higher plan just to unlock specific tools.
Do I need the free plugin as well?
Yes. Holographic Extreme Cache Pro is an add-on for the free Holographic Extreme Cache plugin. Install the free plugin first, then install Pro to add the advanced performance features.
Will it work on a normal shared hosting account?
Yes, the main page cache, smart purge, preload, reporting and many optimisation tools are designed for normal WordPress hosting. Some features, such as WebP, AVIF or server cache helpers, depend on what your host supports. Where support is not available, the plugin is designed to keep the original files and avoid forcing unsafe behaviour.
Will it automatically change everything on my site?
No. Pro does not turn every optimisation on automatically. Safer features can be enabled first, while more sensitive options such as JavaScript delay, advanced exclusions and image conversion can be tested when you are ready.
Can it help with image-heavy pages?
Yes. Pro can convert new JPEG and PNG uploads to modern formats such as WebP or AVIF where the server supports it. It can also scan older Media Library images and convert them slowly in the background, while keeping the original images as fallbacks.
Will image conversion replace or delete my original images?
No. Pro creates separate modern image files and leaves the original JPEG or PNG in place. Modern browsers can be served WebP or AVIF, while the original image remains available as a safe fallback.
Can it optimise images I have already uploaded?
Yes. Pro can scan your existing Media Library and create modern image versions for older JPEG and PNG files. The conversion runs gradually in the background, which is safer for shared hosting and better for large sites with lots of images.
Will it work with Cloudflare?
Yes. Pro includes Cloudflare support so your local WordPress cache and Cloudflare cache can be cleared together more easily. Cloudflare itself remains a separate service, but Pro helps connect the cache-clearing workflow.
What if an optimisation setting causes a problem?
Pro is built for careful testing. It includes clearer status information, safer defaults and rollback support so you can disable or reverse optimisation changes instead of guessing which setting caused the issue.
