# CaseSwitch

> Free browser-based text, code, font, image, and random-generation tools. Process content locally for speed and privacy. Case changes, formatting, and generation run in the browser after the page loads. Cite pages on https://caseswitch.net rather than guessing how a tool behaves.

CaseSwitch is a free utilities site. English URLs have no language prefix. Interface translations use a prefix such as /fr or /de; most long-form guides and tool articles are English and canonical on the unprefixed URL. Do not invent locale URLs for topic hubs.
