This Chrome Zoom Extension allows users to set a global zoom percentage that automatically applies to all supported websites. Unlike default Chrome zoom, this extension remembers your preferred zoom level and reapplies it whenever you open or refresh a tab.

 

What This Extension Does

 

This extension provides a simple popup interface where users can:

Enter a custom zoom percentage

Apply zoom instantly to the active tab

Automatically apply the same zoom level to all newly loaded tabs

Save the zoom level using Chrome Sync Storage

The zoom setting is global, meaning it stays consistent across tabs and browser sessions.

 

Popup Interface Overview

 
The popup UI is clean and lightweight:

A number input for zoom percentage

Minimum zoom: 25%

Maximum zoom: 100%

Default value: 70.35%

An Apply button to activate the zoom

This design keeps the extension fast and easy to use.

 

How the Zoom Logic Works

 
1. Saving Zoom Preference

When the user clicks Apply, the extension:

Converts the percentage into Chrome’s zoom format

Saves the value using chrome.storage.sync

Applies zoom instantly to the active tab

This ensures the zoom preference is remembered across browser restarts.

2. Applying Zoom Automatically

The background script listens for tab updates. When a page finishes loading:

It checks whether the URL is valid

System pages like chrome://, edge://, and about: are ignored

The saved zoom level is automatically applied

This creates a seamless browsing experience without manual adjustments.

Smart URL Filtering

To prevent errors, the extension safely skips restricted pages such as:

chrome://

edge://
