Web Data Usage

Discover how much data websites use while you browse.

Web Data Usage combines a built-in web browser with detailed usage tracking, helping you understand which websites and types of content consume the most data. It is especially useful when you have a limited mobile data plan—or when you are simply curious about the hidden cost of loading a webpage.

See estimated usage for the current page, today’s total for the website, and the accumulated total for each browser tab. Tap the usage panel for a detailed breakdown of text, images, audio, video, and other content.

### How to Use

Enter a website address or search term in the address field and browse normally. The data usage panel updates as page resources load.

Tap the usage summary to switch between the total view and the detailed content breakdown. Open the More menu to access daily, weekly, and monthly reports, search your history, manage tabs, or reset the current tab’s usage.

For tracking in Safari, enable the Web Data Usage Safari extension and grant it access to websites. You can then open the extension from Safari’s toolbar to see the current page’s estimated usage and today’s total for that website.

Add the Daily Usage widget to your Home Screen for a quick overview of today’s total, website count, and content categories.

Please note: Data usage figures are estimates based on detectable website resources and may differ from the totals reported by your mobile carrier or internet provider.
