How to use this tool

Paste your text, then select a conversion. The converted text appears in the result box. Copy the result to use it in your document; your original input remains available.

A worked example

“hello WORLD” becomes “HELLO WORLD” in uppercase, “hello world” in lowercase and “Hello World” in title case.

How it works & what to check

Title case capitalizes words mechanically. Sentence case capitalizes text at sentence boundaries. Neither mode understands personal names, acronyms or an editorial style guide, so check the result.

Common questions

Will title case keep words such as “NASA” unchanged?

No. Automatic title case may turn NASA into Nasa. Proofread names and acronyms after converting.

Does this change Urdu or Arabic letters?

Urdu and Arabic do not use uppercase and lowercase in the same way as Latin scripts, so those letters generally remain unchanged.

Can I copy the converted text?

Yes. Use Copy result. If clipboard access is unavailable, the text is selected so you can copy it manually.
