Privacy-first utility tools.

Free Web Toolbox is designed around client-side calculations whenever possible. Favorite tools are stored in local browser storage so they remain available on the device you used to save them. Do not paste passwords, private keys, account secrets, or sensitive personal records into any online tool unless you control the environment.

The site counts privacy-friendly first-party analytics events such as tool result views, searches, shares, copies, downloads, and ad clicks so we can improve the pages people actually use. These event records avoid storing raw IP addresses and expire from the analytics store after 90 days.

Advertising and optional analytics partners may use cookies, device identifiers, and measurement technologies according to their own policies. You can clear browser storage or block cookies through your browser settings.
