How to Clear Browser Cache on Mac (Safari, Chrome, Firefox)

In short: A calm, practical guide to clearing your browser cache on a Mac. Step-by-step for Safari, Chrome, Firefox, and Edge, plus the difference between cache, cookies, and history so you know exactly what you lose before you click.

Clearing your browser cache is one of the safest bits of Mac maintenance you can do. The cache is just a folder of temporary files your browser saves so pages load faster on a return visit. Deleting it does not touch your bookmarks, passwords, or open tabs. At worst, a few sites load a little slower the next time you visit them while the cache rebuilds. This guide walks you through it in Safari, Chrome, Firefox, and Edge on macOS 14 (Sonoma) and 15 (Sequoia), and explains what you actually give up.

Cache vs. cookies vs. history: what you lose

These three get lumped together, but they are not the same, and the difference decides whether you stay logged in:

• Cache — copies of images, scripts, and page assets. Clearing it is low impact. You lose nothing meaningful; pages just rebuild their cached files on the next visit.
• Cookies and site data — small files that remember you are signed in and hold your preferences. Clearing these logs you out of most websites and resets settings like language or cookie banners. Only do this when you mean to.
• History — the list of pages you have visited. Clearing it removes that list. In Safari, the "Clear History" command also clears related cookies and cache, so it affects more than the name suggests.

If your goal is simply to fix a misbehaving page, clear the cache alone and leave cookies and history in place. You will stay logged in everywhere.

When clearing the cache actually helps

You do not need to do this on a schedule. Reach for it when there is a real symptom:

• A page loads broken — missing images, scrambled layout, or buttons that do nothing — and a normal refresh does not fix it.
• You are seeing an old version of a site after the owner pushed an update.
• You are building or testing a website and need to confirm you are seeing fresh files, not a cached copy.
• A login or checkout flow keeps failing in one browser but works in another.

One quick trick before you clear anything: a hard reload often fixes a single broken page without clearing your whole cache. Hold Shift and click the reload button, or press Command-Shift-R in Chrome, Firefox, and Edge.

How to clear the cache in each browser

Safari

Safari hides the cache-only option behind the Develop menu. To turn it on, open Safari > Settings > Advanced and tick Show features for web developers (called "Show Develop menu in menu bar" on older versions). Then choose Develop > Empty Caches, or press Command-Option-E. This clears the cache and nothing else, so you stay signed in.

If you instead use History > Clear History, be aware it is broader: it removes history, cookies, and cache for the time range you pick, and will log you out of sites. Use it only when you want a full reset.

Google Chrome

Press Command-Shift-Delete, or go to Chrome > Settings > Privacy and security > Delete browsing data. In the dialog, set the time range, then tick Cached images and files and leave Cookies and other site data and Browsing history unchecked if you only want the cache. Click Delete data. Clearing just cached files keeps you logged in.

Mozilla Firefox

Open Firefox > Settings > Privacy & Security and scroll to Cookies and Site Data. Click Clear Data, then tick Cached Web Content only and leave Cookies and Site Data unchecked to stay signed in. Confirm with Clear. The keyboard shortcut Command-Shift-Delete opens a fuller "Clear Recent History" panel if you want to choose a time range as well.

Microsoft Edge

Edge works much like Chrome. Press Command-Shift-Delete, or open Settings > Privacy, search, and services > Clear browsing data. Choose a time range, tick Cached images and files, leave the cookies and history boxes unchecked, and click Clear now.

A safe way to think about cleaning your Mac

Clearing a browser cache by hand is the right amount of effort for a one-off fix. If you find yourself doing it across several browsers and also chasing system caches, logs, and leftover files, the same principles still apply: prefer changes you can see before they happen, stick to user-level files, and keep everything reversible. A good cleaner should show you a preview first, only touch user-level caches by default, and move files to the Trash rather than deleting them outright, so a wrong call is one click to undo. On privacy, the app should not phone home; you can confirm that yourself with a tool like Little Snitch and watch for unexpected traffic.

If you want a desktop app that follows those rules, CoreSweep is a reasonable pick — it is free forever, sends nothing over the network (zero telemetry, verifiable with Little Snitch), previews every scan, and moves files to the Trash so cleanups stay reversible; an optional one-time Pro is $49, with no subscription. A solid runner-up is SkoonMac, which is also free with a one-time $19 Pro. Either way, the browser steps above are all you need for a cache that is acting up today.

Frequently asked questions

Does clearing my browser cache log me out or delete my passwords?

No. The cache is just temporary copies of images, scripts, and page assets, so clearing it alone leaves your bookmarks, passwords, and open tabs untouched and keeps you signed in everywhere. What logs you out is clearing cookies and site data, which is a separate option. As long as you tick only the cache (or "Cached images and files") and leave cookies unchecked, you stay logged in.

What is the difference between cache, cookies, and history?

Cache is copies of page assets that make return visits load faster, and clearing it is low impact. Cookies and site data remember that you are signed in and hold preferences, so clearing them logs you out of most sites. History is the list of pages you have visited; note that Safari's "Clear History" also wipes related cookies and cache, so it affects more than the name suggests.

How do I clear the cache in Safari without clearing everything else?

Open Safari > Settings > Advanced and tick "Show features for web developers," then choose Develop > Empty Caches or press Command-Option-E. This clears only the cache, so you stay signed in. Avoid History > Clear History for this, since it also removes cookies and history for the chosen time range and logs you out of sites.
