How to reject all cookies automatically in Chrome

Last checked: 6 October 2026

Hunting for “Reject all” on every site gets old fast. A browser extension can do it for you. But not every extension that makes banners go away actually rejects, so it helps to know what each kind does.

In short:

Hiding a banner is not the same as rejecting it

Extensions deal with cookie banners in three ways:

Some extensions mix these. “I don't care about cookies”, for example, says on its store page that it mostly blocks or hides banners, and accepts them when a site needs it to work.

Your options

Free tools that reject common banners. Consent-O-Matic, made by researchers at Aarhus University, is free and open source. It fills in the banners it knows with the choices you set, and picks the most private option where a site's choices are unclear. Ghostery's free extension includes Never-Consent, switched on by default, which rejects on the sites it supports. Ghostery says that covers the cookie pop-up makers most websites use, and that more are added with every release. If those cover the sites you visit, they're a good choice.

Tools that make banners go away. “I don't care about cookies” and its community copy say they mostly block or hide banners. uBlock Origin Lite, a free ad blocker, has a list of cookie notices you can switch on so they're filtered out.

Cookie Chomper. Known banners are recognised and rejected right on your computer, like the free tools do. Banners a site made itself are read to find their Reject button, even when it's tucked away behind “Settings”. For that, a limited part of the banner's words goes to our server; never the web address, your cookies or what you type into forms. It's paid: 14 days free, then €6 a year.

There's a side-by-side table on cookie banner extensions compared.

When there's no Reject button

Some banners only offer “Accept all” and “Settings”. With Cookie Chomper, the settings are opened, everything the site doesn't need is switched off, and your choice is saved, even when the site calls that button “Save & accept”. Cookies are never accepted for you.

When it's “accept or pay”

Some sites say: accept our cookies, or pay to get in. You can't reject for free there, so that choice is left to you.

What we tested

We let Cookie Chomper visit 10,312 websites across Europe: the 313 busiest, and 10,000 picked at random from the rest of the top million. 4,886 of them showed a cookie banner. Leave out the banners that offered no way to reject, and about 9 in 10 were rejected. Of the rejected banners, 7 in 10 were recognised straight away, on your computer. The rest were read first.

No “Accept”, “Accept all”, “I agree” or pay button was pressed. One site’s only save button said “Save & accept”. It was pressed with every optional category switched off, and the site recorded nothing as accepted. Version 0.1.2, tested 1 October 2026. The full result is on the home page. We haven't tested other extensions the same way, so we can't say how they compare.
