A lightweight ad blocker that speeds up YouTube, Facebook and every site you use

Why most blockers are heavy

Many popular blockers load filter lists with 80,000+ rules. Every rule is matched against every request, and the lists sit in memory the whole time your browser runs. On low-end machines that means noticeable lag and higher RAM use.

How a small rule set can block just as much

The bulk of ads come from a relatively small number of ad networks. AdOff uses around 130 targeted rules that cover the vast majority of ad traffic, instead of tens of thousands of mostly-redundant ones. Fewer rules, matched faster, with a tiny footprint.

Because ad and tracker requests are blocked before they load, pages render faster and use less network — so the blocker pays for itself in speed.

Lightweight doesn't mean weak

AdOff still does network blocking, cosmetic filtering, video ad neutralization and stealth anti-detection. It's small because it's precise, not because it cuts corners.

Frequently asked questions

Do ad blockers slow down Chrome?

Heavy ones can, by loading huge filter lists into memory. A lightweight blocker like AdOff speeds Chrome up by blocking ad requests before they load.

What is the lightest ad blocker for Chrome?

AdOff is ultra-light — a fraction of the size of typical blockers — because it uses a small, targeted rule set instead of giant filter lists.

Does a lightweight ad blocker block fewer ads?

Not necessarily. AdOff's ~130 targeted rules cover the vast majority of ad networks, so it blocks effectively while staying small.
