Speed Boost — Performance Booster

Speeds up every website on slow/old computers: kills animations, blur & shadows, pauses autoplay video, blocks ads & trackers.

Speed Boost — Performance Booster for Slow & Old Computers Make every website load faster and feel snappier — even on an old laptop, a budget Chromebook, a low-RAM office PC, or an older macOS. Speed Boost automatically strips out the CSS animations, blur effects, autoplay videos, trackers, and heavy background scripts that make modern websites feel sluggish on hardware that wasn't built for them. One click, every site, instantly lighter. No sign-up. No account. No data collection, no analytics, nothing phoning home. Install it and the web gets lighter — that's the whole product. WHY YOUR BROWSER FEELS SLOW Most "my computer is slow" problems aren't your computer's fault — they're the website's. Modern pages are stuffed with looping CSS animations, parallax scrolling, backdrop blur ("frosted glass" / glassmorphism UI), drop shadows on every card and button, auto-playing background videos, oversized uncompressed images, and dozens of invisible ad and tracking scripts firing in the background on every single page load. On a brand-new machine with a dedicated GPU you barely notice. On an older laptop, a Chromebook, a netbook, a budget desktop, or any computer with limited RAM and integrated graphics, all of that adds up fast: laggy scrolling, spinning fans, hot laptops, draining battery, and pages that take forever to feel responsive even after they've "finished loading." Speed Boost turns all of it off before it ever has a chance to slow you down. EVERYTHING SPEED BOOST CAN TURN OFF Visual effects — the biggest CPU & GPU drain on old hardware • Kill CSS animations — stops looping, scroll-triggered, and hover-triggered animations dead in their tracks • Kill transitions — removes animated hover and state-change effects across every button, menu, and card • Remove blur & glass effects — disables backdrop-filter / frosted-glass UI, one of the single heaviest GPU costs on integrated graphics • Remove shadows — strips box-shadow and text-shadow rendering overhead site-wide • Disable smooth scrolling — restores instant, lag-free, old-school scrolling • Disable parallax backgrounds — stops expensive scroll-linked background effects from repainting on every scroll event • Use fast system fonts — swaps custom web fonts for your operating system's built-in fonts, so text renders immediately instead of waiting on font downloads and layout shifts Loading & network — fewer requests, less to download • Block auto-playing videos — stops muted hero videos, background clips, and social-feed autoplay from eating CPU, GPU, and bandwidth the instant a page loads • Lazy-load images & iframes — defers everything below the fold so the visible part of the page renders immediately instead of waiting on images you haven't scrolled to yet • Block ads & trackers — a built-in blocklist kills ad scripts, tracking pixels, and analytics beacons before they ever load, cutting both page weight and the dozens of silent background network requests that quietly slow every page down Extreme mode — for truly underpowered hardware or very slow connections • Hide all images & video — a one-click, text-only reading mode for the absolute fastest possible page loads on very old devices, metered or slow internet connections, or low-bandwidth / data-saver situations PER-SITE CONTROL Speed Boost isn't all-or-nothing. Every setting applies globally by default, but you stay in control of individual sites: • Fully turn Speed Boost off on specific sites, with wildcard support (*.example.com) to cover an entire domain and all of its subdomains in one rule • Switch any single site to Default or Custom mode and fine-tune exactly which effects are disabled there, right from the toolbar popup — no digging through settings • Manage everything from a full options page: global defaults, a searchable list of sites you've turned Speed Boost off for, and a searchable, expandable list of per-site custom configurations • Know at a glance whether it's active — the toolbar icon itself visibly dims whenever Speed Boost is off, either globally or just for the site you're currently on, so you're never left guessing WHO THIS IS FOR • Anyone browsing on an old laptop, an aging MacBook, a Windows 7/8/10/11 machine with modest specs, a Chromebook, a netbook, a budget desktop, or a work, school, or library computer with limited RAM or an integrated GPU • Students and office workers stuck with company-issued or school-issued low-spec hardware • Gamers and multitaskers who want to reclaim CPU, GPU, and RAM being eaten by background browser tabs • Anyone on a slow, metered, rural, or unreliable internet connection who wants lighter pages and fewer wasted megabytes • Anyone who finds autoplay video, flashing animations, or parallax scrolling distracting, overwhelming, or physically uncomfortable — including people with motion sensitivity or vestibular disorders who need a calmer, lower-motion browsing experience • Privacy-minded users who want fewer third-party trackers and ad scripts loading on every page by default • Developers, QA testers, and support staff who want a one-click way to preview how a site behaves in a stripped-down, low-power environment PRIVACY Speed Boost runs entirely on your device. It does not collect, store, sell, or transmit any browsing history, personal information, or usage analytics — there is nothing to sign up for, nothing syncing to a server, and nothing phoning home. Its only network-facing behavior is blocking requests, never making them. What happens in your browser stays in your browser. AVAILABLE IN 19 LANGUAGES The full interface — popup, settings, and every label — is translated into English, German, Turkish, Russian, Spanish, Italian, French, Swedish, Polish, Chinese, Japanese, Arabic (with complete right-to-left layout support), Portuguese (both Brazilian and European), Korean, Dutch, Hindi, Vietnamese, and Indonesian. It automatically matches whatever language your browser is already set to — nothing to configure. SIMPLE, INSTANT, FULLY REVERSIBLE Click the toolbar icon to see and control everything: one master switch for every site, a quick toggle for the site you're currently on, and one-tap access to the full settings page. Changes apply after a quick tab reload — no browser restart, no account, no complicated setup, nothing to configure before it starts working. Turn any part of it off again at any time, globally or per site, with a single click. 100% FREE, NO CATCH Speed Boost is completely free, with no premium tier, no ads of its own, no upsells, and no in-extension purchases. There is no limited trial and nothing that stops working after a few days. Every feature described here — global defaults, per-site rules, wildcards, extreme mode, and all 19 languages — is available to everyone, for free, forever. GETTING STARTED IN THREE STEPS 1. Install the extension and pin it to your toolbar 2. Visit any website — Speed Boost is active everywhere by default, no setup required 3. Click the toolbar icon any time you want to check its status, turn it off for one site, or jump into the full settings for fine-grained, per-site control FREQUENTLY ASKED QUESTIONS Does Speed Boost slow down or break websites? No — it only removes decorative effects (animations, blur, shadows, parallax) and defers non-critical loading (images, autoplay video, ad/tracker scripts). Core site functionality, forms, navigation, and content are never touched. If a specific site ever looks or behaves differently than you'd like, turn Speed Boost off for just that one site in two clicks. Does it collect any of my data? No. Speed Boost collects nothing — no browsing history, no analytics, no personal data, no account required. It runs fully locally in your browser. Can I use it on just some websites and not others? Yes. Use the options page to fully disable Speed Boost on specific sites (with wildcard *.domain.tld support for whole domains), or switch a site to Custom mode to keep Speed Boost on there while adjusting exactly which effects apply. Will this replace my existing ad blocker? Speed Boost includes its own lightweight ad- and tracker-blocking rules as part of its performance toolkit, but it's designed primarily as a performance extension, not a dedicated ad-blocker replacement. Many users run it alongside a dedicated ad blocker without conflicts. Does it work in languages other than English? Yes — the interface automatically follows your browser's language and is fully translated into 19 languages, including full right-to-left support for Arabic. Is it free? Yes, completely, with no premium tier or hidden costs.
