About Janeer
A growing collection of free developer and text utility tools, built for speed, privacy and simplicity.
What Is Janeer?
Janeer is a suite of browser-based tools designed for developers, writers, students and anyone who works with text and data. Every tool on the site runs entirely in your browser using client-side JavaScript. Your input is never sent to a server, stored in a database, or shared with third parties.
The collection includes everyday utilities like a word counter and case converter alongside developer-focused tools such as a JSON formatter, Base64 encoder, regex tester, hash generator and more. Each tool is a standalone page that loads instantly, works offline once cached, and requires no account or installation.
Why Janeer Exists
Too many online tools are buried behind sign-up walls, bloated with ads, or quietly send your data to remote servers. Janeer takes a different approach: every tool is free, fast and private by default. There is no account system, no paywall, and no server-side processing of your input.
The site is built with plain HTML, CSS and JavaScript. No frameworks, no build steps, no unnecessary dependencies. This keeps pages lightweight, accessible and easy to maintain. Every page is designed to meet WCAG 2.1 AA accessibility standards with semantic markup, keyboard navigation and proper contrast ratios.
Who It Is For
Janeer is for anyone who needs a quick, reliable utility without the overhead. Software engineers use the JSON formatter and regex tester daily. Technical writers rely on the word counter and markdown converter. Students and researchers reach for the case converter and lorem ipsum generator. If you work with text or code, there is a tool here for you.
Privacy First
All Janeer tools process data exclusively in your browser. The text you type, the JSON you format, the hashes you generate never leave your device. The site uses privacy-first Cloudflare Web Analytics — no cookies, no cross-site tracking, no personal data collected — to understand traffic patterns. Your tool input is never included in any analytics data. For full details, see the Privacy Policy.
