Automated Optimization: Streamlines the process of optimizing images by scheduling background tasks without the need […]
Load SVG Inline Tag as URL
Feature: The “Load SVG Inline Tag as URL” option in W3Speedster determines how SVG images are rendered. Instead of embedding the full SVG code inline in the HTML (which increases DOM complexity), this setting enables loading SVGs as external files via standard <img> tags. Why This Setting is Important Improved Page Performance: Prevents HTML bloat […]
Pixels to Load Resources Below the Viewport
Feature: The “Pixel to Load Resources Below the Viewport” setting in W3Speedster determines how far below the visible viewport deferred resources begin loading. The default threshold is 200 pixels, which ensures images, videos, iframes, background images, and audio start loading just before they enter view, resulting in a smooth and uninterrupted user experience. Why This […]
Enable Lazy Load
Feature: The Enable Lazy Load feature in W3Speedster defers the loading of images and other non-critical media elements until they are about to enter the user’s viewport. Instead of loading all visual assets (Images, Audio, Video, and Iframe) at once, this approach prioritizes above-the-fold content, leading to significantly faster initial page rendering and optimized server […]

Feature: The WebP Image Quality setting in W3Speedster determines the compression level applied when converting JPG and PNG images into the WebP format. As a next-generation image format developed by Google, WebP provides significant file size reduction while maintaining strong visual quality. W3Speedster defaults this value to 90%, offering a near-lossless balance between clarity and […]
