How to Block Ads on Any Device: Browser, Phone, and Network-Wide Options
Ad blocking does more than remove banner ads. It cuts tracking pixels, blocks malicious ad networks that sometimes serve malware, speeds up page loads significantly, and reduces mobile data consumption. This guide covers the most effective methods on each platform, from a browser extension you can install in 30 seconds to a network-wide solution that blocks ads on every device in your home.
Method 1: Browser Extension (Windows and Mac)
uBlock Origin is the standard recommendation – it is free, open source, lightweight, and blocks more than any other browser extension with less CPU and RAM usage than competitors like AdBlock Plus. Install it from the Chrome Web Store (works on Chrome, Brave, Edge, and Opera), Firefox Add-ons, or Safari Extensions.
After installing, it works immediately with no configuration needed. The default filter lists block ads on virtually every major site. If a site does not block correctly, click the uBlock Origin icon and click the power button to temporarily disable it for that site – some news sites and small blogs rely on ads for revenue and ask you to whitelist them, which you can choose to do.
Important for Chrome users: Google began restricting extensions under Manifest V3 in 2024, which weakened some ad blockers. uBlock Origin Lite is the MV3-compatible version for Chrome. For the full uBlock Origin experience, use Firefox – it still supports Manifest V2 extensions and enforces no such restrictions.
Method 2: Ad Blocking on iPhone
Safari on iOS supports content blockers – apps that provide filter lists to Safari without being able to see your browsing activity (a privacy advantage over browser extensions on desktop).
- Download AdGuard or 1Blocker from the App Store. Both have free tiers that cover basic ad blocking.
- After installation, go to Settings > Safari > Extensions and enable the content blocker from the app you installed.
- Open Safari and reload any page – ads should be gone.
For system-wide blocking on iPhone (covers all apps, not just Safari), you need a DNS-based solution. AdGuard has a free DNS option: go to Settings > General > VPN & Device Management > DNS and configure a custom DNS. Use AdGuard’s DNS server addresses, which block known ad and tracker domains for every app on the device.
Method 3: Ad Blocking on Android
Chrome on Android does not support extensions, so the browser extension approach does not work. Options:
- Use Firefox for Android – unlike Chrome, Firefox on Android supports the same uBlock Origin extension as the desktop version. Switch your default browser to Firefox for Mobile to get full ad blocking while browsing.
- AdGuard app – the paid version ($2.99/month or one-time purchase) installs a local VPN on Android that filters traffic from all apps, not just the browser. This is the most comprehensive per-device option.
- Private DNS: Android 9 and later supports DNS over TLS. Go to Settings > Network & Internet > Private DNS and enter
dns.adguard.com. This blocks ad domains system-wide without any app, though it is less comprehensive than a dedicated filter.
Method 4: DNS-Based Blocking (All Devices)
DNS-based ad blocking works at the domain level – instead of loading and hiding ads, it prevents your device from connecting to ad-serving domains at all. This works for any device on your network including smart TVs, game consoles, and IoT devices that cannot run extension software.
Free DNS-based options that require no hardware:
- AdGuard DNS (94.140.14.14) – set this as your DNS in your router to cover all devices automatically
- NextDNS – configurable cloud DNS with custom block lists; free for 300,000 queries/month, $1.99/month after that
- Cloudflare 1.1.1.1 for Families (1.1.1.3) – blocks malware and adult content, limited ad blocking
Set these in your router admin panel under LAN or DHCP settings – Primary DNS and Secondary DNS fields. Every device on your network then uses this DNS automatically.
Method 5: Pi-hole (Network-Wide, Most Powerful)
Pi-hole is a self-hosted DNS server that runs on a Raspberry Pi (or any always-on Linux machine) and blocks ad domains for every device on your network. It is more powerful than cloud DNS services because you control the filter lists and can customize them completely.
Setting up Pi-hole requires:
- A Raspberry Pi ($35-$75 depending on model) or an old PC running Linux
- About an hour to install and configure
- Pointing your router’s DNS to the Pi-hole’s local IP address
The result: every device in your home gets ad blocking without any configuration on the devices themselves. Smart TVs, Roku boxes, gaming consoles, phones – all benefit. Pi-hole also gives you a dashboard showing exactly how many DNS queries are blocked and by which domains, which makes for fascinating data about how much ad traffic normally flows through a home network (typically 15-25% of all DNS queries).
Which Method Should You Use?
| Method | Effort | Coverage | Best For |
|---|---|---|---|
| uBlock Origin | 2 minutes | One browser | Desktop browsing |
| Safari content blocker | 5 minutes | Safari on iPhone | iPhone web browsing |
| Firefox + uBlock (Android) | 5 minutes | Firefox browser | Android browsing |
| Router DNS change | 10 minutes | All devices, all apps | Whole home |
| Pi-hole | 1-2 hours | All devices, all apps | Tech-savvy users |
Start with uBlock Origin on your desktop browser – it delivers the most impact for the least effort. If you want protection across your whole home, changing the DNS server in your router takes ten minutes and covers every device automatically.
