How it works
Unicode-aware, so accents survive
É becomes é, Ñ becomes ñ, and Greek and Cyrillic lowercase correctly too. Scripts without case — Arabic, Hebrew, CJK — pass through untouched instead of being corrupted.
It does not know what a proper noun is
Lowercasing a paragraph lowercases names, places and acronyms along with everything else. That is usually not what you want for prose pasted in capitals — sentence case is, because it lowercases everything and then restores the capital at the start of each sentence.
What it does
Instant, as you type
No button, no waiting. The conversion is a string operation on text already in the page.
Copy or download
Clipboard or a .txt file, whichever suits what you are doing next.
Private by construction
The page makes no network requests, so the text cannot leave your browser.
Practical advice
Getting a better result
- For a block of text pasted in capitals, sentence case is almost always the better choice — it puts the sentence starts back rather than leaving you to fix them by hand.
- Lowercasing is a useful normalising step before comparing or deduplicating lists, since it makes “Apple” and “APPLE” match.
- Proper nouns are not protected. Read the result before using it for anything published.
Questions
Things people ask
Will it lowercase names and acronyms too?
Yes — it has no way to tell a name from any other word. If you are fixing text that arrived in capitals, use the sentence case option in the case converter instead, which lowercases everything and then capitalises the first letter of each sentence.
Does it handle Turkish or German correctly?
It uses your browser’s Unicode case mapping, which handles German ß and most European scripts correctly. Turkish dotted and dotless i follow a locale-specific rule that a general-purpose conversion does not apply, so check that case if it matters to you.
