Test Your Web Designs at Every Resolution

Resize Browser is a system tray utility built for web developers and application designers who need to verify their work at multiple screen resolutions. Instead of changing your display settings every time you want to test a different viewport, Resize Browser resizes any browser window to standard resolutions like 640x480, 800x600, and 1024x768 -- or any custom width and height you specify.

The utility sits quietly in your Windows system tray until you need it. Right-click the tray icon to quickly resize a detected browser window, or open the main interface to see a list of all running browser windows. Resize Browser supports multiple browsers including Internet Explorer, Firefox, and Mozilla, and it automatically detects new browser windows as they open.

Additional options let you keep the resize tool on top of other windows, compensate for the Windows taskbar when calculating dimensions, center the resized browser within your current screen resolution, and set an auto-refresh interval for the browser list. Whether you are building a new website or testing an existing application at different viewports, Resize Browser makes the process fast and painless.

Who Is This For?

  • Web developers -- Test pages across different viewports without changing your display resolution.
  • QA testers -- Verify layouts at standard resolutions to catch rendering issues before deployment.
  • Application designers -- Preview applications at any window size to ensure proper scaling and alignment.
  • Anyone -- who needs to quickly resize windows to precise pixel dimensions for screenshots, demos, or presentations.

Key Features

Standard Resolutions One-click presets for 640x480, 800x600, and 1024x768 -- the most common screen resolutions for testing web designs.
Custom Sizing Enter any width and height you need. Resize Browser saves your last custom size so you can reuse it without re-entering the dimensions.
Multi-Browser Support Works with Internet Explorer, Firefox, Mozilla, and any other browser or program window you want to resize.
System Tray Minimizes to the Windows system tray and stays out of your way until you need it. Right-click the icon for quick access to all resize options.
Stay On Top Keep the resize tool visible above other windows so you can resize browsers without switching back and forth between applications.
Auto Refresh Automatically detects new browser windows every 10 seconds so you never have to manually refresh the browser list.
