A production-grade WebView tailored for content that benefits from magnification. An unobtrusive top overlay exposes − / + zoom, a Reset action, and a live percentage readout, while pinch and double-tap gestures stay enabled for natural scaling. The widget respects your enforced width/height, renders smoothly at high DPI, and keeps navigation, security, and JS bridge capabilities you expect from a full WebView—ideal for hybrid apps and embedded documentation.

Functionality

• Overlay zoom toolbar: minus/plus, Reset to 100%, live % indicator; configurable min/max and step.

• Gestures: pinch-to-zoom, double-tap zoom, inertial scrolling; optional disable/lock zoom.

• Layout modes: Fit to width/height, original size, remember last scale per origin; maintain scroll on scale.

• Navigation: back/forward/reload, pull-to-refresh, load progress, error/empty states.

• Fullscreen support for media/maps; safe-area aware; hardware-accelerated rendering.

• URL handling: http/https, mailto:/tel:/custom schemes, deep links & target=_blank popups.

• JavaScript bridge: evaluate JS, postMessage channels, expose native callbacks.

• Storage & headers: cookies, local/session storage, custom headers, user-agent override.

• Security: domain allow/deny list, SSL/mixed-content policies, optional sandboxed mode.

• Accessibility & i18n: keyboard focus, screen-reader labels, RTL and Reduce Motion support.

• Platforms: iOS (WKWebView), Android (Android WebView), with desktop/web fallbacks.

Use cases

• Viewing documentation, diagrams, tables, PDFs or dense dashboards that need zoom.

• Kiosk/POS experiences where staff must quickly magnify web UIs.

• Embedding maps, charts, and design specs with precise scaling.

• Knowledge bases, help centers, and support flows inside a native shell.

• Hybrid apps mixing native navigation with web features (SaaS panels, paywalls, forms).
