Resource Prioritization — Faster Page Loading (2026)
Pages feel slow even on fast internet? SuperchargePerformance loads what you see first, deferring off-screen images and scripts so pages become usable sooner.
Updated
Resource Prioritization delays the loading of content that is not yet visible on your screen — images below the fold, embedded iframes, and off-screen resources — so Chrome can focus bandwidth and CPU on what you actually see first. The result is a faster time-to-interactive: the visible portion of the page is ready sooner, even if the full page takes the same total time to load.
How It Works
When a browser loads a page, it typically fetches all images, iframes, and scripts in the order they appear in the HTML — regardless of whether they are in the visible viewport. Resource Prioritization intercepts this behavior and defers requests for resources that are off-screen at the moment the page loads.
The deferral is dynamic: as you scroll and an off-screen resource enters (or approaches) the viewport, the request is released and the resource loads normally. From a user perspective, the page appears to load faster because the content you interact with first is ready sooner.
Settings
| Level | What Gets Deferred | Availability |
|---|---|---|
| Low | Below-the-fold images | Free |
| Med | Below-the-fold images and iframes | Free |
| PRO | All off-screen resources including some scripts | PRO |
The default is Med. This setting provides a clear improvement in perceived load speed on content-heavy pages without the compatibility risk of PRO mode.
When to Use This
- You visit long-form content pages (news articles, blog posts) with many images that load before you scroll to them
- Pages feel slow to become interactive even though your connection is fast
- You want to reduce initial bandwidth usage when loading pages on a metered or throttled connection
- You use PRO level for maximum performance and want to defer script loading on off-screen sections
Combine Resource Prioritization with Font Optimization to reduce both download size and loading order overhead. Use Preloading to pre-fetch likely next pages while this feature ensures current-page resources are loaded efficiently.
Privacy
Resource prioritization is handled entirely within your browser using local logic. No page content, resource URLs, or scroll position data is transmitted anywhere. Everything runs on your device.
