A toolkit that stays on your machine

Case Conversion Tool is a static website. You paste text, pick a transform, and copy the result. The work happens in JavaScript in this tab — not on a server, not in a database, and not behind an account wall.

The flagship is a case converter with writing modes and programming cases on one surface, plus dedicated pages for the tools people search for. The visual language is ink on a near-white canvas: high contrast, quiet chrome, a mesh gradient only in the hero.

What you can do here

Convert writing case and programming identifiers, clean pasted text, count words, encode or decode, generate passwords and UUIDs, restyle Unicode for social bios, and format JSON, YAML, CSV, or Markdown. Everything runs in this tab.

How it stays private

The site is HTML, CSS, and JavaScript. Conversions, file reading, and OCR (where offered) use browser libraries. There is no account and no conversion API. Optional preferences such as theme live in localStorage on your device.

We are not a clone of any existing converter. The product bet is simple: faster than a noisy ad page, more precise than a single unnamed “title case,” and honest about privacy.

The catalog will grow. OCR, PDF, and other heavy features will only ship if they can run with browser libraries — still without uploading your files.
