Tool ID: lowercase. Requested language: br. Description language: en. Complete guide translation: no; untranslated sections use English.

## Overview (en)

Lowercase Converter turns every capital letter in your text into lowercase while keeping spacing, punctuation and line breaks untouched. Casing follows the language you choose, with English, Turkish, German and French available, or the interface language by default. This matters for Turkish text, where a capital I becomes the dotless ı and İ becomes a plain i.

## Questions (en)

### How do I lowercase Turkish text correctly?

Choose Turkish under Text language. The converter then maps the capital I to the dotless ı and the dotted İ to a plain i, following Turkish rules. With English selected, a capital I becomes an ordinary i instead.

### Can I convert a whole document to lowercase at once?

Yes. Paste the full text and the entire input is converted in one pass, with paragraphs and line breaks preserved. Inputs above 20,000 characters need an explicit run instead of updating live as you type.

### Will lowercasing remove accents or special characters?

No. Accented capitals keep their accent, so É becomes é, and characters without case, such as digits, symbols and emoji, are left as they are. Use a separate accent remover if you also want plain letters.
