Screen Magnifier

Une loupe qui suit votre curseur. Appuyez sur Alt+Z pour activer.

[Product Overview] Screen Magnifier is a lightweight Chrome extension designed for situations that demand precise visual inspection. By overlaying a magnifier lens that tracks your mouse cursor in real time, you can zoom into any area of the screen without adjusting the browser's zoom level. [Key Features & Technical Highlights] Dynamic Cursor Tracking: The magnified area follows your cursor instantly, powered by an inertia-smoothing algorithm that balances tracking accuracy with visual fluidity. Non-Intrusive Operation: Toggle the magnifier on or off instantly with the Alt + Z shortcut (fully customizable), without disrupting the page's layout or interactive behavior. Press ESC to exit at any time. Flexible Display Settings: Zoom level (1x–5x), lens size, and lens shape (circle, rounded rectangle, or square) are all adjustable in real time and remembered automatically — while keeping CPU and memory usage minimal. [Why Install It] Reduce Visual Fatigue: When dealing with small fonts, low-contrast color schemes, or information-dense pages, you can read clearly without zooming the entire page — significantly easing eye strain during long sessions. Professional Use Cases: Gives front-end developers and UI designers instant pixel-level inspection (pixel-checking) to verify spacing, alignment, and fine rendering details — without switching to an external design tool. Accessibility Enhancement: As a complement to the browser's built-in accessibility features, it provides on-demand local magnification for users with low vision or those who need zoom assistance — no additional software required. 【產品簡介】 Screen Magnifier 是一款輕量化的 Chrome 擴充功能，專為需要精細視覺操作的使用情境而設計。透過即時追蹤滑鼠游標的放大鏡疊層，使用者無需調整瀏覽器縮放比例，即可隨時聚焦於螢幕任意位置的細節。 【核心功能與技術優勢】 動態游標追蹤： 放大區域隨游標即時移動，並採用慣性平滑演算法，兼顧追蹤精確度與視覺流暢性。 非侵入式操作： 以 Alt + Z 快捷鍵（可自訂）瞬間啟用或關閉，不干擾網頁原有的排版與互動行為；亦可按 ESC 鍵快速退出。 靈活的顯示設定： 放大倍率（1x–5x）、鏡頭尺寸與形狀（圓形、圓角、方形）均可即時調整並自動記憶，同時保持極低的 CPU 與記憶體佔用。 【安裝理由與使用價值】 降低閱讀疲勞： 面對小字體、低對比配色或高資訊密度的頁面，無需放大整個網頁即可清晰閱讀，有效減輕長時間盯螢幕的視覺負擔。 專業領域輔助： 為前端開發者與 UI 設計師提供即時的像素級檢視能力（Pixel-checking），方便核對間距、對齊與細節呈現，無需切換至外部設計工具。 無障礙體驗補強： 作為瀏覽器內建無障礙功能的補充，為弱視或需要放大輔助的使用者提供隨開即用的局部放大支援，無需安裝額外軟體。
