How to clear cache?

A cache is a stored copy of web page assets — images, scripts, stylesheets — that your browser saves locally so pages load faster on repeat visits. Over time this cache grows large and can cause display glitches, show outdated versions of pages, or simply consume gigabytes of disk space.

In Chrome or Edge, press Ctrl + Shift + Delete, set the time range to "All time," check "Cached images and files," and click Clear data. In Firefox the same shortcut opens a similar panel. On Safari (Mac), go to Safari → Settings → Advanced, enable the Develop menu, then Develop → Empty Caches. On Safari for iPhone, go to Settings → Safari → Clear History and Website Data.

On Android, cache clearing is done app by app. Go to Settings → Apps → [App name] → Storage → Clear Cache. Some Android phones also have a "Device care" or "Storage" section that offers a bulk cache clear. On iPhone, you typically delete and reinstall an app to clear its cache, or use the offload feature under Settings → General → iPhone Storage.

Clearing the cache logs you out of most websites because session cookies are usually cleared alongside it. If you only want to fix a display glitch on one site, a "hard refresh" (Ctrl + Shift + R on Windows, Cmd + Shift + R on Mac) forces the browser to re-download that single page's assets without clearing everything else.

For a computer-wide cache clear beyond the browser, tools like BleachBit (Windows/Linux) or CleanMyMac (Mac) can clear system-level temp files. However, the browser cache is almost always the most impactful starting point.
