They remember different things
Browser cache stores reusable parts of web pages, such as images and other downloaded files. This can help pages load without fetching every part again. Mozilla’s HTTP caching guide explains how stored responses are reused and checked.
Cookies are small pieces of site information that can support things like sign-in and preferences. Google’s cookie guide explains what they do and how to manage them.
Think of these as different questions: “Does my browser have a reusable copy of this page file?” and “What does this site remember about my visit?” Clearing one category does not mean you have cleared everything.
Start with the smallest useful check
If one site looks wrong, reload it first. Note the page address, the error, and whether the problem happens after signing in. Try another page on the same site and a different site.
If several unrelated sites are slow on multiple devices, the connection may be a better place to investigate. Our slow Wi-Fi guide can help you make that comparison.
For a single stubborn site, change one thing at a time and retry the same action. This makes it easier to explain what helped if you later contact support.
Clear cached files for a fresh download
Clearing cache makes the browser fetch page files again. It can help when stored content is involved, but it will not repair a website’s server or fix every sign-in problem. The next visit may take longer as files download again.
In desktop Chrome, open the menu and choose Delete browsing data. Review the time range and select Cached images and files for a cache-only cleanup. Check every selected category before confirming. Google’s browsing data guide describes the controls.
Other browsers and mobile versions use different labels. Use the support instructions for your browser rather than selecting a broad reset simply because it is easy to find.
Treat cookies and site data as a separate step
Deleting cookies can sign you out of websites and reset saved preferences. If one site is the problem, look for its individual site-data controls before clearing every site. Google documents this in its cookie guide.
Site data can also include information stored locally by web apps. Save or export unfinished work first when possible. A browser cleanup is not a backup of that work.
Clearing cached files alone does not delete saved passwords. Broader cleanup dialogs contain other categories, so review the choices instead of using “select all.”
When clearing data does not help
Write down what you tried and contact the site’s support team if the same problem continues. Include the browser, device, page, and exact error, while leaving passwords and private account information out of the message.
Browser extensions or other browser settings may also be involved. Mozilla’s Firefox troubleshooting guide provides a sequence of checks, including its troubleshooting mode. Follow the guide for your own browser.
You can stop after the page works. Clearing more categories is not a required finishing step.
