When to Clear Browser Cache—and When Not To

Troubleshoot stale website files without deleting useful data unnecessarily.

After a site update, cached files can make the page appear broken. Clearing all browser data can also sign you out or remove preferences, so start with the smallest test.

Try a hard refresh

Ask the browser to fetch page resources again, or compare behavior in a private window. If the issue disappears there, cached files or extensions may be involved.

Know cache versus cookies

Cache stores resources such as scripts and images; cookies and site storage can hold session state. Clear data for one site when possible instead of removing everything.

Verify the actual fix

Reload and repeat the action that failed. If multiple browsers and devices show the same problem, it may be server-side rather than local browser state.

Before relying on the result, test a small example, keep an original copy when a file or value is transformed, and check the output in the application where you plan to use it. Browse the tools directory for a utility that matches your task, and use the other practical guides for related checks.
