  • Different browsers have separate storage spaces
  • sessionStorage clears when you close the tab/browser

Local Storage Vault - Complete Browser Storage Management Tool

Our Local Storage Vault provides comprehensive management for your browser's web storage. Easily view, edit, export, and import localStorage and sessionStorage data with a clean, intuitive interface designed for developers and power users.

What is Web Storage?

Web Storage is a web browser feature that allows websites to store data locally on a user's computer. Unlike cookies, web storage data is not sent to the server with every request, and it provides much more storage capacity (typically 5-10MB per domain). There are two types:

localStorage

Stores data with no expiration date. Data persists even when the browser is closed and reopened. Perfect for storing user preferences, application state, or cached data that should persist between sessions.

sessionStorage

Stores data for one session only. Data is cleared when the page/tab is closed. Ideal for temporary data, form data during a multi-step process, or any information that shouldn't persist beyond the current session.

Common Use Cases

Technical Details

Web Storage operates under specific constraints and behaviors:

Frequently Asked Questions

Is my data safe when using this tool?

Absolutely! All operations happen entirely in your browser. No data is sent to any server. The tool only accesses storage data for the current domain (webtoolify.in), and you have full control over what you view, edit, or delete.

Can I use this tool to view other websites' storage?

No, due to browser security policies (Same-Origin Policy), this tool can only access storage data from its own domain. You cannot view storage data from other websites using this tool.

What happens if I exceed the storage limit?

Browsers will throw a "QuotaExceededError" when you try to exceed the storage limit. This tool shows you how much space you're using and how much remains, helping you stay within limits.

Why can't I store objects directly?

Web Storage only supports string values. To store objects, arrays, or other data types, you must convert them to strings using JSON.stringify() before storing, and parse them back with JSON.parse() when retrieving.

How does sessionStorage differ from localStorage?

sessionStorage is tied to a specific browser tab/window and lasts only as long as that tab/window is open. localStorage persists across browser sessions and tabs. Both have the same API but different persistence scopes.

Can I recover deleted storage data?

Once you delete data from web storage, it cannot be recovered unless you have a backup. This tool provides export functionality to create backups before performing deletions or clearing operations.
