What is lowercase text?
Lowercase text uses small letters (a, b, c) instead of capital letters (A, B, C). 변환ing text to lowercase is one of the most common text operations: it normalizes data before sorting or searching, fixes CAPS LOCK accidents, and prepares text for URLs, emails, and database lookups where case matters.
This free lowercase converter runs entirely in your browser. Paste any text — a paragraph, an essay, a list, or a whole document — and every uppercase letter is converted to lowercase instantly. There is no upload, no signup, and no limit: your text never leaves your device.

Frequently asked questions
What does converting text to lowercase mean?
Lowercase is the small-letter form of writing (a, b, c). 변환ing to lowercase changes every capital letter to its small form, which helps normalize data, emails, usernames, and URLs.
Does it handle accented 글자 and Unicode?
Yes. The converter uses JavaScript's native toLowerCase, which follows the Unicode standard, so accented letters (é, ü, ñ) and non-Latin scripts are converted correctly.
Is my text uploaded anywhere?
No. Everything runs locally in your browser with vanilla JavaScript. Your text never leaves your device and nothing is stored or tracked.
Can I also convert to UPPERCASE or Title Case?
Yes — use the 대소문자 변환 for UPPERCASE, Title Case, and Sentence case, or the dedicated 소문자→대문자 tool.
