Clear Safari Website Data on Mac

Safari keeps cookies, caches, and local storage for every domain you visit. Clearing that website data is the quickest fix for a site that's stuck misbehaving — and the fastest way to sign yourself out of everything, so it pays to know exactly what gets removed. Here's how to clear data for one site or all of them, on macOS 13 Ventura, 14 Sonoma, and 15 Sequoia alike.

When clearing website data is the right fix

Reach for it when one specific site has gone wrong and reloading doesn't help:

• A login loop — the site bounces you back to the sign-in page over and over.
• Stale content that survives a refresh, or a shopping cart that won't update.
• A cookie-consent banner that reappears on every page, or a layout that broke after a site update.
• You want to see a site as a first-time, signed-out visitor.

All of those live in the site's cookies, cache, and local storage — exactly what this removes.

Clear data for one site

1. Open Safari and press Command-comma to open Settings.
2. Click the Privacy tab, then Manage Website Data…
3. Give the list a moment to populate, then type the site's domain into the search field.
4. Select the matching entries, click Remove, then Done.

Each entry in the list says what it holds — cookies, cache, local storage — so you can see at a glance whether a site has been quietly stockpiling offline data.

This is the move when a single site is broken — login loops, stale pages, a cart that won't update. Removing its data resets that one site to a clean slate while every other tab keeps its logins. The path hasn't changed across Ventura, Sonoma, or Sequoia.

Remove all website data

In the same Manage Website Data sheet, click Remove All and confirm. Every site forgets you: you're signed out everywhere, cookie-consent banners come back, and any offline data a web app stored is gone. Pages may load a touch slower on the first visit while caches rebuild. There's no undo button for this one — recovery is simply signing back in, which is why it matters that your passwords survive (next section).

What clearing touches — and what it doesn't

• Removed: cookies, cached site files, and local storage or databases for the sites you cleared.
• Side effect: you're signed out of any site that kept you logged in with a cookie.
• Untouched: browsing history, bookmarks, and saved passwords. Passwords live in a separate encrypted store — System Settings → Passwords, or the dedicated Passwords app on macOS 15 Sequoia — so signing back in is one autofill away.

The reverse doesn't hold, though: Safari's History → Clear History… command deletes website data along with your history, and because history syncs through iCloud it clears on your other devices too. If you only want site data gone, use Manage Website Data and leave Clear History alone.

Website data itself is per-device: clearing it on your Mac doesn't touch the cookies on your iPhone or iPad, so repeat the process there if you're resetting a site everywhere.

How much space does this actually free?

Usually less than you'd hope. The Manage Website Data list labels what each site stores — cookies, cache, local storage — and most entries measure in kilobytes. The exceptions are heavy web apps that keep offline databases. If your real goal is disk space rather than fixing a site, website data is small change next to Safari's page cache and download history.

Chasing space or speed instead?

Safari's page cache usually dwarfs its website data. See how to clear Safari's cache for the Develop-menu route that empties caches without signing you out of anything.
