Seraphinite Accelerator (Full)

The plugin uses a file-based cache and revalidates cached pages to help limit repeated work on the server. Its cache can account for different devices and user environments, and it supports caching pages tailored to individual users. This can suit sites with dynamic content, including shopping carts and online courses.

Seraphinite Accelerator (Full) also optimizes the files and media sent to visitors. It can minify HTML, CSS, and JavaScript, apply lazy loading to images, videos, frames, and fonts, and defer or inline scripts and styles. Encoding options include GZip, Deflate, Compress, Brotli, and uncompressed formats. The plugin also supports multiple CDNs and browser caching.

• File size reduction: Minifies JavaScript, CSS, and HTML files to reduce the amount of content sent to visitors.
