Low Vision Magnifier

Turn your cursor into a magnifying glass with a hotkey. Adjust zoom level and shortcut in the popup.

🔍 Struggling to read small text on websites? Low Vision Magnifier turns your cursor into a powerful magnifying glass — just hold a hotkey and a circular zoom lens appears, following your mouse in real time. Designed for people with low vision, elderly users, and anyone who needs a quick, effortless way to enlarge web content without changing page layout or zoom settings. ✨ KEY FEATURES 🎯 Hold-to-Activate Magnifying Lens Press and hold Alt, Shift, or Ctrl to instantly activate the screen magnifier. A circular lens appears at your cursor and zooms into whatever is underneath. Release the key and it disappears — no clutter, no interruption. 🔎 Adjustable Zoom Level (1.5x to 5x) Slide from a gentle 1.5x all the way to a powerful 5x magnification. Find the zoom level that works best for your eyes. ⭕ Adjustable Lens Size (100px to 400px) Choose a small, focused lens (100px) for precise inspection or a large lens (400px) for comfortable paragraph reading. ⌨️ Choose Your Hotkey Pick the modifier key that fits your workflow — Alt, Shift, or Ctrl. Switch anytime from the popup settings. 🖱️ Smooth 60fps Cursor Tracking The magnifying lens follows your cursor with buttery-smooth animation. No lag, no stutter — just fluid, real-time magnification as you move across the page. 🧠 Smart Input Detection Automatically detects when you are typing in a text field or form. Holding Shift to capitalize or Alt for a shortcut will not trigger the lens unexpectedly. 🔄 Auto-Recapture on Scroll and Resize Scroll the page or resize the window and the magnifier recaptures the visible area automatically. The lens always shows current content. 🌙 Dark Mode Support The settings panel and the lens automatically adapt to your system's dark mode preference. Comfortable in low-light environments. ☁️ Settings Sync Across Devices Your hotkey, zoom level, and lens size are saved to Chrome Sync. Log into Chrome on another computer and your settings are already there. 🔒 Fully Private — Zero External Requests No analytics, no tracking pixels, no telemetry. Everything runs locally in your browser. Your browsing activity stays completely private. 🎯 HOW IT WORKS Step 1 — Install the extension from the Chrome Web Store and pin it to your toolbar for easy access to settings. Step 2 — Click the extension icon to open settings. Choose your preferred hotkey (Alt, Shift, or Ctrl), set your zoom level, and adjust the lens size. Step 3 — Navigate to any webpage. Press and hold your chosen hotkey. A circular magnifying lens appears at your cursor position, showing a zoomed-in view of the content underneath. Step 4 — Move your mouse while holding the key. The lens follows your cursor in real time, letting you inspect text, images, and fine details across the entire page. Step 5 — Release the hotkey to dismiss the lens. It vanishes instantly, returning your view to normal. Activate it again anytime with a single key press. 🔒 PRIVACY AND SECURITY Low Vision Magnifier is built with privacy as a core principle. No data collection — Zero user data collected. No browsing history, no personal information, no usage statistics. No analytics or tracking — No analytics scripts, no tracking pixels, no third-party services. No external requests — All resources bundled locally. Zero network requests. Ever. Permission: storage — Saves your three settings (hotkey, zoom level, lens size) via Chrome Sync. No other data is stored. Permission: activeTab — Captures a screenshot of the visible tab to render the zoomed view inside the lens. Never transmitted or saved. Permission: host_permissions (all URLs) — Injects the magnifier on every webpage so the lens works on any site. The extension does not read, modify, or transmit page content. 💡 USE CASES Reading Small Text on Websites Many websites use small font sizes or low-contrast text that are difficult for people with low vision or age-related vision changes. Glide the magnifying lens over the text and read comfortably at up to 5x magnification. Inspecting Fine Details in Images Examine a product photo, map detail, or chart legend. The cursor zoom lens lets you inspect any part of an image at high magnification without opening a separate viewer. Accessibility for Elderly Users Older adults who struggle with small text can use on-demand, localized magnification that works instantly without altering page layout or browser zoom settings. Web Developers Testing Readability Check text rendering, font sizes, icon clarity, and pixel-level details directly in the browser. A fast alternative to DevTools for visual inspection. Proofreading and Editing Writers and editors can zoom into specific words or punctuation, catching typos and formatting issues that are easy to miss at normal zoom. ⭐ WHY CHOOSE LOW VISION MAGNIFIER Built for Accessibility First This is not a novelty zoom tool. Low Vision Magnifier is designed specifically for people who need magnification to use the web comfortably. The hold-to-activate model means the lens is always one keypress away but never in the way. Lightweight and Fast The entire extension is under 200KB. There is no build system, no framework overhead, no background processes consuming memory. The service worker activates only when needed and goes idle immediately after. Works on Every Website The magnifier content script injects on all pages — news sites, online stores, web apps, PDFs in the browser, internal tools behind a login. If Chrome can display it, this screen magnifier can zoom it. No Page Modification Unlike browser zoom (Ctrl +/-) that reflows the entire page, Low Vision Magnifier overlays a lens on top of the page without changing layout, breaking responsive designs, or shifting content. The page stays exactly as it is.
