Chrome 97 Release Highlights: Site Data Deletion, Enhanced Web‑App UI, Mobile Zoom Memory, and CSS HDR Support

Chrome 97 has been officially released today, bringing better tools for deleting stored site data, more consistent web apps, finer zoom control on mobile browsers, and the controversial keyboard mapping API.

Delete all data of a site

Chrome 97 made some changes to privacy and security settings. You can now delete all data of a site. Previously you could only delete all site data or delete individual cookies. This new setting can be found in Settings → Privacy and security → Site Settings → View permissions and site data.

Web apps look more like native apps

Previously the area that made web apps look unlike native apps was the top app bar. Chrome 97 allows web apps to use this space for a search bar, navigation buttons, colors, and other elements, making the UI feel more native.

Remember each site's zoom settings on mobile

Desktop Chrome already remembers per‑site zoom settings and keeps them on each visit. Chrome 97 adds a feature flag that enables the same behavior on mobile.

The feature can be found in chrome:flags#enable-accessibility-page-zoom . Once enabled, you can adjust zoom by clicking the lock icon in the address bar, and Chrome will remember the setting for the next visit.

Better HDR support for CSS

Google started testing a CSS feature in Chrome 94 to detect whether a device screen supports HDR content. This feature is now live in Chrome 97, allowing developers to enable HDR only on displays that support it, improving user experience.
