Description
VoidResizer is a precision viewport resizer tool designed for web designers and developers who need real viewport size control — not just window outer dimensions.
Unlike most resizer extensions that only resize the browser’s outer frame, VoidResizer adjusts your viewport to the actual visible area. This is critical in browsers like Arc Browser, where sidebars, toolbars, or UI chrome distort the real viewport size.
Key Features:
• True viewport resizing — no more approximations; what you set is what you get.
• Domain-specific overlay toggle — activate a real-time size overlay per domain, persistent until you turn it off.
• Live draggable overlay — shows current viewport size, customizable position remembered per domain.
• Preset manager — create, edit, delete presets (HD, mobile, tablets, ultrawide, 4K).
• Import/Export presets — easily share and manage size configurations.
• Clean, no-clutter UI — no ads, no analytics, no tracking.
VoidResizer is built for pixel-perfect responsive testing, whether you’re working on mobile layouts, tablet breakpoints, or ultra-wide designs.
It’s a simple, focused tool — designed to solve a very real problem that other extensions miss.
