How to Clear Local Storage: Complete Browser Data Guide (2025)

What is local storage?

Local storage is a type of browser storage that websites use to keep data on your device. Unlike cookies, which have expiration dates, local storage keeps information indefinitely until you remove it. This can include settings, preferences, or even cached content from websites.

Why clear local storage?

• Free up space: Some sites store large amounts of data locally, slowing your browser over time.
• Protect your privacy: Saved site data can reveal your browsing habits if left unchecked.
• Fix site errors: Old or corrupted storage entries may cause sites to misbehave.
• Stay in control: Clearing local storage ensures websites can’t store endless data on your device.

When should you clear local storage?

You don’t need to clear local storage daily, but it’s smart to clean it if you notice slow websites, errors with site settings, or after visiting sites you don’t trust. Regular cleaning every few weeks keeps your browser healthy.
