Why Do You Have to Clear Cache?

You certainly don’t have to, not as a regular part of computer or smartphone maintenance, anyway. However, a few good reasons to clear cache come to mind…

Clearing your cache forces your browser to retrieve the newest copy available from the website, something that should happen automatically but sometimes does not.

You might also want to clear the cache if you’re experiencing issues like 404 errors or 502 errors (among others), sometimes indications that your browser’s cache is corrupted.

Another reason to delete browser cache data is to free up space on your hard drive. Over time, the cache can grow to a really large size, and so clearing it out can recover some of that previously used space.

Regardless of why you might want to do it, clearing your cache is really easy to do in all the popular browsers in use today.

Chrome: Clear Browsing Data

In Google Chrome, clearing the browser cache is done via the Clear browsing data area in Settings. From there, check Cached images and files (as well as anything else you want to remove) and then tap or click the CLEAR DATA button.

Assuming you’re using a keyboard, the quickest way to Clear browsing data is via the Ctrl+Shift+Del keyboard shortcut.

Without a keyboard, tap or click the Menu button (the icon with three stacked lines) followed by More tools and finally Clear browsing data….

See How to Clear the Cache in Chrome [support.google.com] for more details.

Choose All time from the Time range option at the top of the Clear browsing data window to make sure you get everything.

In Chrome’s mobile browser, go to Settings from the three-dotted menu at the bottom, and then Privacy. From there, choose Clear Browsing Data. In this menu, check Cached Images and Files and press the Clear Browsing Data button once, and then again for confirmation.

Internet Explorer: Delete Browsing History

In Microsoft Internet Explorer, the browser that comes pre-installed on most Windows computers, clearing the cache is done from the Delete Browsing History area. From here, check Temporary Internet files and website files and then click or tap Delete.

Like with other popular browsers, the fastest way to the Delete Browsing History settings is via the Ctrl+Shift+Del keyboard shortcut.

Another option is via the Tools button (the gear icon), followed by Safety and then Delete browsing history.

Internet Explorer often refers to the browser cache as temporary internet files but they’re one in the same.

Firefox: Clear Recent History

In Mozilla’s Firefox browser, you clear the cache from the Clear Recent History area in the browser’s Options. Once there, check Cache and then tap or click Clear Now.

The Ctrl+Shift+Del keyboard shortcut is probably the fastest way to open this tool. It’s also available from Firefox’s Menu button (the three-lined hamburger icon) via Options, then Privacy & Security, and finally the clear your recent history link from the History area.

See How to Clear the Cache in Firefox for a complete tutorial.

Don’t forget to choose Everything from the Time range to clear set of options, assuming that’s the time frame you want to clear the cache over.

If you’re using Firefox’s mobile app, tap the menu from the bottom right and then choose Settings from that menu. Find the PRIVACY section and tap Clear Private Data. Make sure Cache is chosen and then tap Clear Private Data. Confirm with an OK.

Firefox Focus is another mobile browser from Firefox that you can clear the cache from using the ERASE button on the top right of the app.

Safari: Empty Caches

In Apple’s Safari browser, clearing the cache is done via the Develop menu. Just tap or click Develop and then Empty Caches.

Screenshot of the Empty Caches option in Safari

With a keyboard, clearing the cache in Safari is super easy with the Option-Command-E shortcut.

If you don’t see Develop on your Safari menu bar, enable it via Safari > Preferences, then Advanced, followed by selecting the Show Develop menu in menu bar option.

See How to Clear the Cache in Safari [help.apple.com] if you need more help.

Screenshot of Safari preferences in iOS showing Clear History and Website Data

Clearing the browser cache from mobile Safari, like the one on your iPad or iPhone, is accomplished in a different app. From your device, open the Settings app and then find the Safari section. In there, scroll toward the bottom and tap Clear History and Website Data. Tap Clear History and Data to confirm.

Opera: Clear Browsing Data

In Opera, clearing the cache is done via the Clear browsing data section that’s part of Settings. Once open, check Cached images and files and then click or tap Clear browsing data.

Screenshot of the Clear Browsing Data screen in the Opera browser

The fastest way to bring up the Clear browsing data window is via the Ctrl+Shift+Del keyboard shortcut.

Without a keyboard, click or tap the main menu button (the Opera logo from the upper-left hand side of the browser), then Settings, Privacy & security, and finally the Clear browsing data button. Check the Cached images and files option and then press Clear browsing data.

See How to Clear the Cache in Opera [help.opera.com] for detailed instructions.

Be sure to choose the beginning of time option at the top so you’re sure to erase everything!

You can clear the cache from the mobile Opera browser, too. Tap the Opera icon from the bottom menu and then navigate to Settings > Clear to choose what to delete: saved passwords, browsing history, cookies and data, or all of it.

Edge: Clear Browsing Data

In Microsoft’s Edge browser, included in Windows 10, clearing the cache is done via the Clear browsing data menu. Once open, check Cached data and files and then tap or click Clear.

Screenshot showing how to clear the Edge cache in Windows 10

The fastest way to the Clear browsing data menu is via the Ctrl+Shift+Del keyboard shortcut.

Another option is via the Settings and more button (that little icon with three horizontal dots), followed by Settings and then the Choose what to clear button under the Clear browsing data heading.

See How to Clear the Cache in Microsoft Edge [support.microsoft.com] for more extensive help.

Tap or click Show more while in the Clear browsing data menu for additional items you can erase while clearing cached files and images.

To delete cache files from the Edge mobile browser, go into the menu using button on the right side of the menu, and choose Settings. Go to Privacy > Clear browsing data and choose what you want removed; you can pick cache, passwords, form data, cookies, and more.

Vivaldi: Clear Private Data

You clear the cache in Vivaldi via the Clear Private Data area. From there, check Cache, choose All Time from the top menu (if that’s what you want to do), and then tap or click Clear Browsing Data.

Screenshot of the Clear Private Data window in the Vivaldi browser

To get there, tap or click the Vivaldi button (the V logo icon) followed by Tools and finally Clear Private Data.

Like with most browsers, the Ctrl+Shift+Del keyboard shortcut brings up this menu, too.

You can change the Delete Data for option to delete cached items from longer ago than just the last hour.

More About Clearing Caches in Web Browsers

Most browsers have at least basic cache management settings where, at a minimum, you can choose how much space you’d like the browser to use for cached website data.

Some browsers even let you choose to automatically clear cache, as well as other data that might contain private information, every single time you close the browser window.

Check out the links to the more detailed information I provided in most of the browser-specific sections above if you’re interested in learning about how to do any of these more advanced things with your browser’s caching system.

In most browsers, you can overwrite a web page’s stored cache without deleting all the cache collected by the browser. In essence, this will erase and replenish the cache for that specific page only. In most browsers and operating systems, you can bypass the cache by holding down Shift or Ctrl as you refresh.

Originally there was supposed to be a payment portal you could access and register through which would automate much of the process.


However per the Committee’s request this is put on hold so for now you need to follow this procedure.

To shrink PowerPoint Presentations

First, simply choose an image (any one will do) to edit with PowerPoint Picture Tools (all you have to do is double-click the image to open this view).

Next, select the Compress Pictures option to the left of the tool bar.


The resulting popup will give you the option to compress the size of the image you selected (with the Email option being the smallest). By unchecking the “Apply only to this picture” option, you can reduce the size of all the images in your desk. Just be sure to consider how your presentation will be used when making your selection.


That’s all there is to it! Resave your presentation and you’ll see your PowerPoint file has been shrunk down to a much more manageable level. It’s as simple as that.
