How to use the Cookie Consent Banner Generator
- Choose the layout — a bar, a corner box or a centered dialog — and edit the title, message and button labels.
- Keep Settings on to let visitors choose categories (analytics, marketing, preferences), and link your privacy policy.
- Leave Google Consent Mode v2 on if you use Google Analytics or Ads: paste snippet 1 in the
<head>before your Google tag. - Paste snippet 2 before
</body>, and add a “Cookie settings” link to#cookie-settingsin your footer.
What the banner does
- Shows on the first visit and stores the visitor’s choice in
localStorage(not a cookie) for the number of days you set. - Accept all, Reject all and Settings — rejecting is one click and as visible as accepting, which regulators expect under GDPR.
- Any link to
#cookie-settingsreopens the settings, so visitors can change their mind at any time. - Blocks your other tags until consent: scripts marked
type="text/plain" data-cookie-category="analytics"(or marketing, preferences) and iframes withdata-srcrun only after the visitor accepts that category. Withdrawing consent reloads the page so they stop. - It fires a
cookie-consentevent ondocumentwith the choices, so you can load other scripts only after consent.
Google Consent Mode v2
Snippet 1 sets every Google consent signal — ad_storage, ad_user_data, ad_personalization and analytics_storage — to denied before your Google tag loads. When the visitor chooses, the banner updates them: analytics to analytics_storage, marketing to the three ad signals. Google Analytics then records full data only for visitors who agreed, and cookieless pings for the rest. Since March 2024 Google requires Consent Mode v2 for ads measurement of visitors in the European Economic Area.

Frequently asked questions
How do I add a cookie banner to Webflow?
Paste snippet 1 into Site settings → Custom code → Head (before your Google tag) and snippet 2 into the Footer code, then publish. Add a footer link to #cookie-settings so visitors can reopen it.
Does it block Google Analytics until consent?
With Consent Mode v2, Google Analytics loads but stores no cookies until the visitor accepts analytics — it only sends cookieless signals. To keep other scripts off entirely, load them in a listener for the cookie-consent event.
Is a Reject button required?
Under GDPR, refusing must be as easy as accepting, and several EU regulators have fined sites that hid the reject option. The generator puts Reject next to Accept with the same weight by default.
Can it block scripts until visitors consent?
Yes. Paste your tags in step 3: each one gets type="text/plain" and a data-cookie-category, so the browser doesn’t run it. The banner turns it on when the visitor accepts that category, while necessary tags keep running like an allow list. Iframes such as YouTube embeds wait the same way with data-src.
Where is the choice stored?
In the visitor’s browser (localStorage), with a version and a date, so the banner reappears after the period you set or when you change the version.
Can I install Cookie Consent Banner Generator as a web app and use it offline?
Yes. Cookie Consent Banner Generator is an installable web app (PWA) — installed from your browser, not downloaded from an app store. Click Install app at the top of this page in Chrome or Edge (Windows, macOS, Linux, ChromeOS) or on Android, use Share → Add to Home Screen on iPhone and iPad, or File → Add to Dock in Safari 17+ on a Mac. It then opens in its own window with its own icon, and because it runs entirely in your browser it keeps working offline. Firefox on desktop can’t install web apps. How installing works.
