Make your WordPress site
fast, and keep it that way.
A slow site rarely has one cause. It is heavy images, unused CSS, scripts that load too early and fonts that arrive late. Airlift fixes all of it on every page, with no settings to learn.

You tested your homepage. Your visitors land everywhere else. Airlift speeds up the whole site.
- 01
Sorts your site by design
Your posts share one design, your products another. Airlift groups them.
- 02
Measures a real page
It loads one page from each group in a browser and works out what it needs.
- 03
Speeds up the whole group
Every page with that design benefits, not just the one that was measured.
- 04
Keeps custom pages intact
A landing page with its own design is measured separately, so it still looks exactly right.
The six things that slow WordPress, handled
You cleared the cache.
Your visitors didn’t.
Airlift serves ready-made pages, so your server isn’t rebuilding them on every visit. When you publish, it clears every cache it’s connected to, including your host’s and Cloudflare’s, so visitors see the new version.
How caching worksA shorter trip
to every visitor
Airlift serves your optimized images, CSS, JavaScript and fonts from its own CDN, so every file isn’t travelling from your one server. There’s no separate CDN account to set up.
Explore CDN deliveryKeep your fonts.
Lose the delay.
Airlift hosts your fonts itself, converts them to WOFF2 and trims each file to the characters your pages use. Text stays readable while fonts load instead of popping in late.
Font optimizationThe right image
for every screen
Page builders hide images in CSS backgrounds, inline styles and plugin markup, where many image plugins never look. Airlift finds them, converts them to WebP, sizes each one for the visitor’s screen and loads the one at the top first.
Image optimizationOnly the CSS
each page needs
Your theme loads styles for features you never use, and your page builder adds more. Airlift checks what each page actually uses in a real browser and sends that first, so the page can appear sooner.

Your content shouldn’t
wait on a chat widget.
Chat, popups, analytics and video players don’t need to run before your page appears. Airlift holds them back until the visitor interacts, then loads them so everything still works.
JavaScript optimizationSet up in three steps
You don’t need to know what critical CSS or render-blocking means. Add your site, install the plugin and Airlift does the rest.

No. You don't need to know what critical CSS, lazy loading or render-blocking scripts are. Install the plugin and click optimize. Airlift measures each page and decides what it needs across images, CSS, JavaScript, fonts, caching and delivery. The settings are there if you want them, but you never have to touch them.
Caching helps your server answer sooner. It does nothing about a 2 MB photo at the top of the page, a stylesheet full of rules the page never uses, or a chat widget that loads before your content. Those are usually what PageSpeed Insights is flagging. Airlift fixes them and handles caching too, so you can replace your caching plugin instead of adding another one. Switch off other optimization plugins too, so the same files are not processed twice.
Yes. Airlift works on the finished page your visitors receive, so it doesn't matter how the page was built. It runs with Elementor, Divi, Oxygen, Beaver Builder, Gutenberg, WooCommerce and WPML, and on hosts like Kinsta, WP Engine, Cloudways and SiteGround.
Airlift is designed so it doesn't. Your original files are never changed. Optimizations are applied to a copy as the page is delivered, and if something goes wrong while optimizing, visitors get the original page. You can compare before and after screenshots, exclude any file, and switch off any single optimization.
Every optimization Airlift does, on a limited number of pages and images. That is enough to see the difference on your own site before you pay anything. No card required.
New posts and products use the same layouts Airlift has already optimized, so they get the benefit straight away. When you publish or update a page, Airlift refreshes the cached copy so visitors see the latest version.

The free plan runs on your real pages, so you can see what was slowing them down and compare the before and after yourself. No card required.
