This online text capitalization tool lets you reformat the letter case of any text in seconds. Paste or type your content, choose a capitalization style, and apply it instantly. The tool changes letter case only. Your spacing, punctuation, numbers, symbols, emojis, and line breaks stay exactly as they are. It also includes live text statistics, updating in real time as you type or paste.
How capitalization works
The tool applies a selected casing style directly to your text. It runs in your browser and edits the same text field, so you can immediately review the result.
- No formatting changes: the tool does not rewrap lines or alter spacing. It only changes letter case.
- Non-letters stay the same: numbers, punctuation, symbols, emojis, and whitespace are preserved.
- Predictable rules: each mode follows clear logic described below.
Capitalization styles
Title Case (Capitalize Each Word)
Capitalizes each word while preserving separators (spaces, punctuation, line breaks). The tool finds word-like sequences (letters or digits) and converts them to: first character uppercase, the rest lowercase. Example: “hELLO WORLD” becomes “Hello World”.
Sentence case
Converts the full text to lowercase, then capitalizes the first letter of each sentence. A sentence is detected after common end marks: ., !, ?. It also capitalizes the first letter at the start of the text, including when the text begins with quotes or brackets.
UPPERCASE
Converts letters to uppercase using standard Unicode casing rules. Uppercase letters remain uppercase. Everything else stays unchanged.
lowercase
Converts letters to lowercase using standard Unicode casing rules. Lowercase letters remain lowercase. Everything else stays unchanged.
tOGGLE cASE
Flips the case of each character: uppercase becomes lowercase, lowercase becomes uppercase. Characters that do not have case (numbers, punctuation, symbols) remain unchanged.
Buttons and actions
Apply capitalization
Applies the currently selected capitalization style to the text box and updates the same field. If the text already matches the selected style (no changes would occur), the tool detects that and shows a message.
Copy text
Copies the entire current text box content to your clipboard. If the browser clipboard API is blocked or unavailable, the tool automatically uses a fallback copy method.
Download .txt
Downloads the current text as a plain .txt file using UTF-8 encoding. Only the visible text is saved, including the exact same line breaks and spacing.
Clear
Clears the text box, resets the live stats to zero, and keeps the tool ready for new input.
Live text statistics
The stats panel updates automatically on every change, including typing, pasting, converting, copying, downloading, and clearing.
Characters
Counts every character exactly as it appears in the text box, including letters, numbers, punctuation, symbols, spaces, and line breaks. This is the full string length.
Characters (no spaces)
Counts characters after removing all whitespace characters. Whitespace includes spaces, tabs, and line breaks. In other words, it counts everything except any whitespace.
Words
Counts word-like sequences made of letters or digits. Punctuation and symbols are not counted as words. Contractions with an apostrophe inside a word are counted as one word (for example, don’t).
Sentences
Counts sentence-like segments that end with a period, exclamation point, or question mark (., !, ?). Multiple ending marks like ?! are treated as one sentence ending.
Lines
Counts lines based on line breaks. Each newline creates a new line, including empty lines. If the text box is empty, the line count is zero.
Paragraphs
Counts non-empty text blocks separated by one or more blank lines. Consecutive empty lines are treated as a single separator, so extra spacing does not inflate the paragraph count.
