Case Conversion Tools

TL;DR — convert text to the exact case you need, instantly

Paste your text, pick a case—UPPERCASE, lowercase, Sentence case, Title Case, camelCase, PascalCase, snake_case, kebab-case, or CONSTANT_CASE—then copy the result. Everything runs in your browser; nothing is uploaded.

Case Converter — write once, format everywhere

Titles, code, filenames, captions—everything has a preferred casing. This case converter helps you switch formats without breaking your flow. Paste or type in the editor, hit a button, and get clean, predictable output. It’s frictionless for quick fixes like turning all caps to lowercase, and powerful enough for developer‑friendly formats such as camelCase, PascalCase, snake_case, kebab-case, and CONSTANT_CASE.

What you can do in one click

  • UPPERCASE / lowercase — fast cleanups for emails, captions, and form inputs.
  • Sentence case — great for body copy; keeps the focus on readability.
  • Title Case — polish headlines and headings (capitalizes each word).
  • camelCase / PascalCase / snake_case / kebab-case / CONSTANT_CASE — reliable formats for variables, function names, and file names.
  • Alternating and Inverse — handy for playful copy or quickly undoing an accidental Caps Lock.

Why people use this page

Writers fix shouty text, content teams standardize headings before publishing, and developers normalize identifiers across codebases. The tool splits mixed inputs on spaces, underscores, dashes, and even camelCase boundaries, then rebuilds clean output in the format you chose. While you type, you’ll also see live word, character, line, and sentence counts to keep you within limits.

Privacy matters

Everything runs in your browser—no uploads, no tracking, and no hidden round‑trips. That’s especially useful when you’re working with drafts, proprietary names, or internal documentation.

When to use each style

  • UPPERCASE / lowercase: quick normalization for forms, CSVs, and spreadsheets.

Frequently asked questions

Does this change punctuation or numbers?
No—only letters change case; numbers and punctuation stay the same.
Title Case vs Sentence case—what’s the difference?
Title Case capitalizes every word; Sentence case lowercases the text and capitalizes only the start of each sentence.
Will it handle mixed inputs like ‘helloWorld_my-text’?
Yes. The converter splits on spaces, underscores, dashes, and camelCase boundaries before rebuilding the target format.
Is my text uploaded anywhere?
No—everything runs locally in your browser.
