Chrome Storage Analyzer

Chrome stores browsing history, cache files (images, scripts, pages), cookies, localStorage data, IndexedDB databases, downloaded files, passwords, autofill data, and extension data.

Go to Chrome Settings > Privacy and security > Clear browsing data > Advanced tab to see storage breakdown. Or use chrome://settings/siteData for per-site storage details.

Yes, clearing cache is safe. Websites will load slightly slower on first visit after clearing, but then cache rebuilds. You won't lose passwords, bookmarks, or history unless you choose to clear those too.

Usually cached images and files (50-70%), followed by site data and cookies (20-30%). Extensions with offline data and Progressive Web Apps can also use significant storage.

For optimal performance, clear cache every 1-3 months. Clear cookies only when troubleshooting login issues or privacy concerns, as it will log you out of websites.
