When it comes to web browsers, nothing beats what Google Chrome has to offer. With a market share of more than 63%, chromium is the standard product for most people.

Chrome does many things to speed up page loading, and one of them is pre-filling web pages. In short, Chrome loads the pages it wants to open in the background according to your surfing habits.

In this article we look at how the pre-release works and whether it disrupts your personal life instead of offering you a better experience.

Chrome uses pre-rendering in various ways to speed up the loading speed of web pages. Here is a brief overview of these pre-washing methods.

Chrome pre-plaster

Chrome tries to speed up the pages you regularly visit by sending them in advance. So as soon as you type the first few words of a frequently visited URL, Chrome starts the pre-rendering process in the background.

This pre-rendering ensures that pages load very quickly, because Chrome already starts loading resources for rendering before you even press the Enter key in the address bar.

Web page preselection

Web developers can also use the pre-indexing of Google Chrome to improve the user experience of their website. To enable pre-referencing of web pages, webmasters can include the pre-referencing keyword in their hyperlinks.

This keyword tells Google Chrome to pre-send all pages containing this keyword, so that the pages are loaded immediately when someone clicks on them.

This method of pre-rendering uses nostate prefetch, and no javascript is executed before clicking the link.

Prefabricated MPA

On mobile devices, Google Chrome offers a feature called Accelerated Mobile Pages (AMP) that allows you to view Google’s search results.


These accelerated pages are indicated with a lightning bolt icon in Google searches, and all the resources needed to view the web page are pre-installed. This pre-rendering is the reason for the fast delivery of pages using MPA.

AMP also performs the javascript pre-rendering required to render the page, and even if you do not visit the AMP page, the website publisher can access and modify the cookies it places. AMP pages are served from special AMP caches hosted on Google or Cloudflare servers, and all code is checked to prevent attackers from running malicious javascript code in the background.

While Chrome uses pre-rendering to improve the user experience and accelerate page loading, it collects data such as browsing history, local heuristics and Google crawler data to provide that experience.

If you do not want Google to track every move you make on the web and send information about the web pages you visit to its servers, you can do the following


  • Open a new tab in the Google Chrome browser on your mobile device and click on the three-point icon in the upper right corner.
  • Then click on the Settings button in the drop-down list.
  • Click on the Privacy and Security button on the next page.
  • For faster browsing and searching, click the button next to Preload Pages.
