原文外掛簡介
LessFlux is an external image and video optimization plugin for WordPress that helps reduce media file sizes, improve delivery performance, and offload optimization workloads from your hosting environment.
Unlike traditional optimization plugins that process files directly on your server, LessFlux performs all optimization tasks externally. Images and videos are compressed, converted, and delivered through LessFlux infrastructure, helping reduce CPU usage, memory consumption, and long-running optimization jobs on your WordPress installation.
Whether you’re running a personal website, WooCommerce store, agency portfolio, membership site, or content-heavy publication, LessFlux helps streamline media optimization while keeping your WordPress environment lightweight.
How LessFlux Works
Start instantly in guest mode with one click, no account required, or connect your site using a Website API Key from your LessFlux account.
Upload images or videos as usual.
LessFlux processes media externally and delivers optimized assets through the CDN.
Existing media can be optimized in bulk using background processing.
Bulk optimization jobs continue running even if you close your browser or leave the page.

Bypasses logged-in visitors, cart/checkout/account pages, and any request with a query string

CDN settings are available once you create a free account
Create an account at any time to unlock the full feature set, your site stays connected and your optimized media is kept
External Processing (No Server Load)
One of the main advantages of LessFlux is that optimization workloads do not run on your WordPress server.
All image and video processing takes place externally, helping avoid:
CPU spikes
Memory exhaustion
PHP execution time limits
Long-running optimization tasks
Resource contention on shared hosting environments
This approach is especially useful for large media libraries, WooCommerce stores, agency websites, and websites hosted on resource-constrained environments.
