Local Storage Inspector
See and manage everything this website has stored in your browser: localStorage, sessionStorage, cookies, IndexedDB databases and Cache Storage, with sizes. Edit or delete single items or clear it all; it also shows, hands-on, how browsers keep each site's data separate.

How to use the Local Storage Inspector
- Check the summary: each card shows how many items this site keeps in that storage type and how much space they use.
- Pick a storage type (localStorage, sessionStorage, Cookies, IndexedDB or Cache Storage) to see its items.
- View or edit an item with the Edit button, change the value and press Save item. Use Delete to remove a single item.
- Clear data with Clear all for the current type or Clear all site data for everything, then confirm in the box that appears.
- Press Check storage to refresh after using other tools on this site.
Browser storage types compared
| Storage | Typical limit | Lifetime | Sent to the server? | Common uses |
|---|---|---|---|---|
| Cookies | About 4 KB per cookie | Until expiry date, or end of session | Yes, with every request to the site | Logins, consent choices, analytics and ad IDs |
| localStorage | About 5 MB per site | Until deleted | No | Settings, drafts, theme choice |
| sessionStorage | About 5 MB per site | Until the tab is closed | No | Multi-step forms, temporary state |
| IndexedDB | A share of free disk space | Until deleted or evicted | No | Offline apps, large structured data, files |
| Cache Storage | Shares the IndexedDB quota | Until deleted or evicted | No | Offline copies of pages and assets (service workers) |
Sizes in localStorage and sessionStorage are shown as browsers count them: strings are stored as UTF-16, so every character of the key and the value takes 2 bytes. Cookie sizes are counted in bytes of the name and value.
Why a website can only see its own data
Every piece of browser storage belongs to an origin: the combination of scheme, host name and port, such as https://freetoolcabin.com. The same-origin policy means JavaScript on one origin cannot read localStorage, IndexedDB or cookies of another. That is why no "cookie viewer" website can show you cookies from your bank or social network, and why a tool that claims to clear other sites' data from a web page cannot work. Two more protections apply to cookies:
- HttpOnly cookies are only sent to the server and are invisible to
document.cookie, so they never appear here. Session login cookies are usually HttpOnly. - Partitioning: modern browsers store data of embedded third-party frames (such as ads) separately for each site you visit, which limits cross-site tracking.
How to view and clear data for any site
- Developer tools: press F12 (Cmd+Option+I on Mac) and open the Application tab in Chrome and Edge or the Storage tab in Firefox to see every storage type of the current site, including HttpOnly cookies.
- One site: click the icon left of the address bar, then Cookies and site data (Chrome, Edge) or Clear cookies and site data (Firefox).
- All sites: Chrome and Edge: Settings, Privacy, Delete browsing data. Firefox: Settings, Privacy & Security, Cookies and Site Data. Safari: Settings, Privacy, Manage Website Data.

Frequently asked questions
Can this tool show cookies from other websites?
No, and no website can. Browsers enforce the same-origin policy: a page can only read storage that belongs to its own origin (scheme, host and port). This inspector therefore shows only freetoolcabin.com's data. To see or delete other sites' cookies, use your browser's settings or its developer tools.
Why are some cookies missing from the list?
Cookies marked HttpOnly are hidden from JavaScript to protect them from theft, so document.cookie never includes them. Cookies set for a different path or a subdomain may also not be visible on this page. Ads and other embedded frames have their own separate storage, which this page cannot read either.
What is the difference between localStorage and sessionStorage?
Both store text key-value pairs for one site. localStorage stays until it is deleted, even after you close the browser. sessionStorage belongs to a single tab and is wiped when that tab is closed. Both usually allow about 5 MB per site.
What does this site store in my browser?
Only small preferences for the tools, such as your last settings, saved under keys that start with ftc_. Tools never upload your files or data. Third-party ad scripts that run on this domain may also set cookies or storage items, which will appear in the list.
How do I clear all site data for every website?
In Chrome and Edge open Settings, Privacy, Delete browsing data and choose Cookies and other site data. In Firefox open Settings, Privacy & Security, Cookies and Site Data, Clear Data. In Safari open Settings, Privacy, Manage Website Data. For one site only, click the lock or site icon in the address bar and choose Cookies and site data.
Is it safe to clear this data?
Yes. Clearing it only resets this site's saved tool settings and any data you created here. You will not lose anything on other websites. Data that was only kept in your browser, such as saved lists in a tool, cannot be recovered after deleting it.
