About CaseConvert.top

A collection of free online tools — no signup, no uploads, no paywalls.

What This Site Is

CaseConvert.top is part of a small collection of free online utilities built for people who work with text. This particular tool answers one everyday need shared by writers, editors, students, social-media managers and software developers alike: "Convert this text to the right case format — right now, without retyping it."

Paste any text and pick from 15 case styles: UPPERCASE, lowercase, Title Case (AP-style, with small words kept lowercase), Sentence case, Capitalized Case, camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE, dot.case, path/case, plus the playful aLtErNaTiNg, iNVERSE and lOWER fIRST styles. Every style shows a live preview as you type, one click copies the result, and a batch mode converts lists line by line. Live counters track characters, words, sentences and lines.

Why We Built It

Case conversion sounds trivial until you need it: a headline typed in ALL CAPS, a list of phrases that must become camelCase identifiers, a title that needs proper AP-style capitalization. Existing tools are often buried under ads, capped behind sign-ups, or send your text to a server for no good reason. We wanted a converter that works instantly, in any browser, on any device, without an account — and that never lets your text leave your device, because the conversion is simple enough to do locally.

How It Works

• Runs in your browser: every conversion is performed by JavaScript on your own device. Nothing you type or paste is uploaded, logged, or stored on our servers — see the Privacy Policy. The tool even keeps working if you go offline after the page loads.
• Fifteen modes, one click each: writing styles (Title Case, Sentence case), developer naming conventions (camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE, dot.case, path/case) and fun styles (aLtErNaTiNg, iNVERSE, lOWER fIRST).
• Free and open: every tool on this site is free to use without registration, and always will be.

Independence & Originality

CaseConvert.top is an independent website. It is not affiliated with, endorsed by, or sponsored by any other case-conversion service. All code, text and design on this site are original work. Naming-convention references (camelCase, snake_case and friends) are industry-standard terms, and Title Case rules follow publicly documented editorial style conventions.
