Ad Cleanse removes ads, blocks trackers, and defends your privacy — silently working in the background so every page loads faster and cleaner.
Why Ad Cleanse
Ad Cleanse gives you back the browsing experience the web was supposed to be — fast, focused, and private.
Ads are heavy. Trackers are heavier. By stripping them before they load, Ad Cleanse reduces page weight by up to 60%, making every site noticeably snappier.
Hundreds of ad-tech companies follow you across the web, building profiles to sell your attention. Ad Cleanse blocks them before they can phone home.
Video ads that blare the moment you open a tab are gone. So are pop-overs, overlays, and sticky banners that cover the content you actually came to read.
Malicious ads — known as malvertising — inject malware through legitimate-looking networks. Ad Cleanse uses curated filter lists to block known bad domains before they execute.
Fewer scripts, images, and video assets means your laptop fan stays quiet and your mobile data bill stays predictable. Every blocked ad is bandwidth you keep.
Retargeting ads for things you looked at once are unsettling and distracting. Ad Cleanse keeps your browsing history between you and your browser.
How It Works
Ad Cleanse works at the network request level — it doesn't hide ads after the fact, it stops them from ever being requested.
Before the browser fetches any resource, Ad Cleanse inspects every outgoing request against its filter lists.
Requests to known ad servers, tracking pixels, and analytics endpoints are blocked at the network level — they never reach the server.
Without the weight of ad payloads, pages render faster. No layout shift from ad containers, no scripts fighting for resources.
Ad Cleanse automatically pulls updated filter lists so new ad networks and trackers are blocked as they appear — no action needed from you.
Ad Cleanse collects zero browsing data. No telemetry. No usage stats. Nothing leaves your browser.
