What It Does
Hyperspeed automatically rewrites your theme's JavaScript and CSS assets to remove all unnecessary characters - white space, comments, line breaks - without changing how the code works. The result: significantly smaller file sizes that load faster.
Before/After Comparison
See how minification dramatically reduces file size while preserving functionality:
Before Minification
.button { background-color: #4CAF50; /* Green */ border: none; color: white; padding: 15px 32px; text-align: center; text-decoration: none; display: inline-block; font-size: 16px; margin: 4px 2px; cursor: pointer; }
File size: 247 bytes
After Minification
.button{background-color:#4CAF50;border:none;color:#fff;padding:15px 32px;text-align:center;text-decoration:none;display:inline-block;font-size:16px;margin:4px 2px;cursor:pointer}
File size: 179 bytes (27.53% smaller)
Why It Matters
JavaScript and CSS make up a major part of every page. If they're bloated, your store feels sluggish. Minified files download faster, parse quicker, and reduce Total Blocking Time (TBT), helping your store pass Core Web Vitals tests.
Faster Downloads
Smaller file sizes mean quicker downloads, especially important for mobile users on slow connections.
Better Parsing
Browsers parse minified code faster, reducing the time before your site becomes interactive.
Improved Metrics
Reduce Total Blocking Time (TBT) and improve your Core Web Vitals for better SEO ranking.
Key Techniques Used
Space Reduction
Removes all non-essential spaces, line breaks, and comments without affecting functionality.
Syntax Shortening
Shrinks variable names and removes redundancies when possible for even more savings.
CDN Delivery
Minified versions are served through a CDN for maximum caching and reduced server load.
Safety and Control
We designed our minification with safety as its core principle. Your code integrity is never compromised.
Original Files Preserved
Your original JS/CSS files remain untouched and editable. We only serve optimized versions through our system.
Fully Reversible
Minification is fully reversible with one toggle if you ever need to revert back for any reason.
