Is it safe to delete Safari website data?

Data that websites store on your Mac through Safari, such as sign-in state, settings, databases and offline files.

Usually safe

It can be recreated, but it takes a download, a reinstall or the tool's own command.

~/Library/Containers/com.apple.Safari/Data/Library/WebKit/WebsiteData

~/Library/Safari/{LocalStorage,Databases}

What it is

Websites can save data on your Mac through Safari so they remember you and work faster or offline: local storage, databases and files for web apps. Safari keeps it for each website until the site removes it or you remove it, and macOS clears some of it when storage space is needed. Most sites store little, but web apps and media sites can store a lot.

If it's removed

You may be signed out of the websites whose data you remove, and they may forget your settings. Removing website data in Safari may also change or remove it in other apps.

What to do instead

In Safari, choose Safari > Settings, click Privacy, then click Manage Website Data. Select the websites you want to remove, then click Remove, or click Remove All.
