Window Resize Manager

Resize Chrome windows and view frame or viewport dimensions from a toolbar popup.

Window Resize Manager helps developers, designers, QA testers, and screenshot workflows resize Chrome browser windows without leaving the toolbar. Core features: - Resize the current Chrome window with built-in Phone, Tablet, Laptop, Desktop, and Social/Screenshot presets. - Enter a custom width and height, then rotate the size when orientation changes. - Save, edit, delete, and reuse custom presets locally. - Refill the custom size form from up to three recent custom dimensions. - Switch between outer window sizing and visible viewport sizing. - Read the current window frame size and viewport size from the popup. - Follow live frame and viewport dimensions in a transient active-page overlay while the window changes. The overlay includes the extension icon and an Open action for the popup, then fades away two seconds after resizing stops. - Rate the extension in the Chrome Web Store or send feedback by email from the popup. - Discover Screenshot Capture Studio and PostHog Debugger through static, user-triggered Chrome Web Store links at the end of the popup. - Restore maximized windows to normal size when applying a resize. Privacy and storage: - Presets, recent custom dimensions, and settings stay in Chrome extension storage on your device. - Both Chrome build variants send explicit cookieless usage analytics to PostHog EU Cloud with a `build_variant` event property. - The extension requests regular-website host access only for automatic resize detection and the isolated live overlay; it does not read page content, selected text, full URLs, cookies, website storage, form data, or browsing history. - Analytics events do not include page content, tab titles, preset names, exact dimensions, raw error messages, cookies, or stable personal identifiers. - The live overlay appears during resize flows without requiring the popup to be opened. Window Resize Manager is built for Chrome Manifest V3 and uses a normal extension toolbar popup.
