“Clear browsing data” sounds like one sweeping action, but a browser stores several kinds of information for different reasons. History helps you return to pages. Cookies keep sessions and preferences. Cached files make sites faster. Permissions remember whether a site may use the camera, location, or notifications.
Choosing the right categories matters. Clearing everything can solve a stubborn problem or prepare a device for someone else, but it can also sign you out, erase useful local state, and slow the next visit without removing data already held by websites.
Browsing history
History records addresses and visit times so the browser can suggest pages, color visited links, and show a chronological list. Clearing it removes those local records from the selected time range.
It does not delete records stored by your internet provider, workplace network, search account, or the websites you visited. If history is synchronized, deletion may propagate to other devices, depending on the browser and account settings. Our guide to what browser sync means for your privacy explains that connection.
Cookies and site data
Cookies can hold login sessions, preferences, shopping-cart identifiers, and tracking IDs. “Site data” may also include local storage, IndexedDB databases, and other browser storage used by web applications.
Clearing this category often signs you out and resets site preferences. Offline-capable web apps may lose downloaded content or local drafts. It can resolve corrupted sessions, but it does not force a company to erase information already copied to its servers.
Third-party identifiers may disappear locally, reducing continuity until new ones are created. See what third-party cookies do in your browser for the difference between the small browser token and the larger server-side profile it may reference.
Cached images and files
The cache keeps reusable copies of images, scripts, style sheets, fonts, and other resources. Clearing it forces the browser to download fresh copies, which can fix pages stuck with outdated or incompatible assets.
You normally do not need to clear the cache for routine privacy. Browsers manage its size automatically, and cached files do not usually keep you signed in. The first visit after clearing may be slower and use more bandwidth.
Our article on how browser caching makes pages load faster explains freshness and validation in more detail.
Passwords and passkeys
Saved credentials are usually a separate category. Do not select it casually. Deleting saved passwords can remove the only convenient copy of unique credentials, especially if they are not synchronized or backed up.
Clearing a password from the browser does not change the password at the website. It removes the stored copy used for filling. If you intend to leave a device, also sign out of accounts and review synchronized devices rather than assuming deletion changed server-side credentials.
Before removing a vault, confirm that recovery methods work and that needed credentials exist in another secure location. See how browser password managers protect logins.
Autofill information
Addresses, phone numbers, email details, and payment profiles may be stored separately from passwords. Clearing autofill removes these saved suggestions but does not delete information previously submitted to shops, delivery services, or forms.
If autofill is synchronized, local deletion may affect other devices or may be restored from the account, depending on the setting. Review the category and sync state before clearing it.
Site permissions
Browsers remember decisions for camera, microphone, location, notifications, pop-ups, clipboard access, and other capabilities. Resetting permissions returns sites to their default state, so they may ask again later.
This is useful when you allowed something accidentally or a site behaves incorrectly. It does not delete recordings or location data a site already received. The browser controls future access, not retroactive removal.

Downloads and downloaded files
Clearing the download history usually removes the list shown inside the browser. It does not delete the actual files from the Downloads folder. Conversely, deleting a file from the device may leave its name in browser history until that history is cleared.
These are separate actions because the browser’s record and the operating system’s file serve different purposes.
Hosted app and service-worker data
Some sites install service workers and keep resources for offline use, notifications, or background tasks. Clearing site data can unregister those workers and remove their caches. The site may need to download assets again and ask for permission when revisited.
The Storage Standard and browser APIs define multiple storage mechanisms; MDN’s Storage API overview provides a useful map of how sites manage persistent data.
Time ranges change the result
Most clearing dialogs offer a period such as the last hour, day, week, or all time. The time range may apply differently across categories. A cookie created months ago but used today may not be removed by a narrow historical range, depending on the browser.
When troubleshooting one site, clearing that site’s data is often better than erasing everything. It preserves sessions and preferences elsewhere.
What clearing cannot remove
Local clearing cannot erase:
- website account records and server logs;
- messages, purchases, or forms already submitted;
- provider or workplace network records;
- files synchronized or backed up elsewhere;
- information another device stored independently;
- data already linked to an account or advertising profile.
Deleting an online account or exercising a data-deletion right is a separate process governed by the service and applicable law.
A practical clearing strategy
For a broken page, reload first, then clear that site’s cache and data if needed. For a privacy reset, review cookies, history, permissions, and sync separately. Before giving away a device, sign out, remove the browser profile, and use the operating system’s secure reset process rather than relying on a browser dialog alone.
Chrome’s clearing-data documentation illustrates the categories and their effects in a mainstream browser.
Clear with a purpose
Browsing data is not one substance. Each category supports a different feature and lives at a different boundary. Clearing is most effective when matched to a goal: repair a site, remove local history, reset permissions, sign out, or prepare a device for transfer.
Knowing what remains is as important as knowing what disappears. A careful, selective reset protects useful data while giving you a clearer view of the information that only the website—not the browser—can delete.
