What is the Text Converter tool?
This free case converter changes the case of your text in one tap — no retyping. Paste anything into the box and switch it to UPPERCASE, lowercase, Title Case or Sentence case instantly, or reach for the developer formats: camelCase, snake_case and kebab-case. There is also a reverse option that flips the character order. The conversion happens live in your browser, and your text never leaves your device — nothing is uploaded, logged or stored.
Each transform does exactly what its name says. Uppercase turns «hello world» into «HELLO WORLD» and lowercase does the opposite; Title Case gives «Hello World», while Sentence case capitalizes only the first letter of each sentence. For code and links, camelCase produces «helloWorld», snake_case gives «hello_world» and kebab-case gives «hello-world» — handy for variable names, file names and URL slugs. Reverse turns «hello» into «olleh».
Use it to rescue a paragraph typed with Caps Lock on, normalize headings before publishing, convert uppercase to lowercase in bulk, or generate clean slugs from titles. The text case converter is free, needs no sign-up, and works just as well on a phone as on a desktop. And unlike converters buried in ad mazes, the result appears right under the input with a copy button: paste, tap, copy, done.
How to use the Text Converter
- Paste or type your text into the input box.
- Tap a case chip — UPPER, lower, Title, Sentence, camelCase, snake_case, kebab-case or reverse.
- Read the converted result in the output card — it appears instantly.
- Tap a different chip to try another case; your original input stays untouched.
- Tap «Copy» to put the converted text on your clipboard.
Frequently asked questions
How do I convert uppercase to lowercase without retyping?
Paste the text into the box and tap the lowercase chip — the whole selection is converted at once. Tap uppercase to go the other way. It works on any length of text in one tap.
What is the difference between Title Case and Sentence case?
Title Case capitalizes the first letter of every word («How To Change Text Case»), which suits headings. Sentence case capitalizes only the first letter of each sentence («How to change text case»), which is how normal prose — and this site — is written.
What are camelCase, snake_case and kebab-case used for?
They are programming and web conventions: camelCase for variable names in languages like JavaScript, snake_case for Python identifiers and database fields, and kebab-case for URL slugs and CSS class names. The converter strips spaces and punctuation and joins the words in the chosen style.
Does the case converter work with Arabic text?
Arabic has no upper or lower case, so case transforms leave Arabic letters unchanged — but they still convert any Latin letters mixed into the text, and snake_case, kebab-case and reverse work on Arabic too. It is safe to run mixed Arabic-English text through any option.
Is my text uploaded anywhere when I convert it?
No. The conversion runs entirely in your browser using local code; your text is never sent to a server, stored or logged. Confidential text is safe to convert.
Is it free? Is there a limit on text length?
Completely free, no account and no sign-up. There is no enforced length limit — long documents are bounded only by your browser's memory.
