The process varies slightly depending on your browser. In Chrome, go to Settings > Privacy and security > Clear browsing data. Select 'All time' for the time range and check 'Cached images and files' and 'Cookies and other site data'. Click 'Clear data'. Repeat this process for other browsers like Firefox, Safari, or Edge.
