Optimization and compression of HTML, JS, and CSS to reduce website page weight (data minification)

What this solution does

HTML, JS, and CSS optimization and compression module for 1C-Bitrix. Developer: Artur Golubev. The tool minifies HTML pages, CSS styles, and JavaScript code to reduce the actual weight of downloaded data. This accelerates page loading across all device types and lowers the data volume required for users to open the site.

The module optimizes and compresses HTML, CSS, and JavaScript to reduce web page weight and save user bandwidth. It removes redundant technical data, cleans code, and merges stylesheets linked via the link tag into a single file. Processing covers both inline JavaScript within documents and external JS files. The compression algorithms ensure that visual appearance and site functionality remain unchanged. The process is fully safe and can be disabled by simply turning off the module.

The module optimizes and compresses HTML, JavaScript, and CSS to reduce web page weight. As an example: an initial HTML file of 320 KB and a CSS file of 360 KB are reduced to 190 KB and 325 KB respectively after processing. This results in a traffic saving of 165 KB per page load, approximately 24%. For a site with 300 daily visitors making 5 page transitions each, the monthly traffic saving amounts to approximately 7.1 GB. Reducing the volume of transmitted data accelerates page loading.

Source files remain unchanged, ensuring their safety. The tool uses proprietary compression algorithms distinct from standard libraries. The performed optimization does not affect page rendering and is imperceptible to end users.

The module optimizes and compresses HTML, JavaScript, and CSS to reduce web page weight. It supports multisite configurations, as well as composite and auto-composite generation modes. Compatible with PHP versions 7.x and 8.x. Functions correctly on both current and older versions of the 1C-Bitrix platform. Provides stable operation with most popular ready-made templates, including Aspro, Sotbit, Digital Web, Intec, Alpha, Nextype, and Krait, as well as with sites featuring unique designs.

This module optimizes HTML, JavaScript, and CSS to reduce file size and accelerate page loading. It performs code minification to improve Google PageSpeed Insights scores. For detailed information on capabilities and configuration, refer to the full module documentation.
