Premium scans the saved Elementor layout, merges the LandTech Extras CSS and JavaScript those widgets need, and serves two hashed files instead of a pile of unused library code.
Live demo
The mock above is a CSS toggle. On a real site the compiler writes uploads/ltxe-compiled/post-{id}-{hash}.css and .js, then swaps them in on the public page.
Tap Before to see each widget file. Tap After to see the two compiled files. Unused LandTech widgets never enter the bundle.
What you get
Turn on Smart Asset Compiler, compile a published Elementor page, and the live visit loads two files.
The compiler reads the Elementor JSON and lists every LandTech widget type on the page.
Matching CSS and JS are concatenated and whitespace-collapsed. No extra library is bundled.
Saving in Elementor, updating Premium, or toggling the lane drops the files so the next compile is fresh.
Optional: the first public request builds the bundle (with a short lock so two visitors do not write at once).
jQuery, Elementor core, the editor, Client Feedback and Time Machine stay as their own files.
The filename and enqueue version include a content hash so WP Super Cache, W3 Total Cache and WP Rocket treat a rebuild as new.
How it works
Compile from All Tools, or let the first visitor do it. The Elementor preview never uses the bundle.
Settings → Add-on features → Platform: Smart Asset Compiler. It stays off until you opt in.
Elementor Extras → Asset Compiler. Choose a published page, or tick auto-compile for the first public visit.
Widgets, CSS size, JS size and percent saved. Recompile or clear a row any time.
Use cases
You keep every feature installed. Each page only pays for what it uses.
The homepage uses Mega Menu and Countdown. The product page does not load Mega Menu CSS.
A campaign page with a calculator and tabs compiles two files instead of eight widget assets.
Turn the lane on before launch. Clients keep every widget installed; unused files stay off the wire.
Smart Asset Compiler is part of LandTech Extras Premium, alongside Time Machine, Client Feedback and 50+ other premium features for Elementor.
