Convert and Fix Text Capitalization Online
Inconsistent capitalization is a frequent issue when copying notes, receiving unformatted drafts, or recovering from accidental Caps Lock typing. ToolJiffy’s Text Capitalizer and Case Converter gives you instant control over letter cases with five distinct formatting modes.
Five Practical Capitalization Modes
Select the appropriate formatting mode for your publishing or editing task:
- Sentence case: Capitalizes the initial letter of each sentence after punctuation marks (
.,!,?), keeping subsequent prose letters lowercase. - Title Case: Capitalizes primary words while preserving lowercase for common short prepositions, conjunctions, and articles (e.g. The Art of War).
- Capitalize Every Word: Capitalizes the first letter of each word unconditionally (e.g. for names, addresses, or data fields).
- UPPERCASE: Converts every alphabetical character to capital letters.
- lowercase: Converts all characters to lower case.

For example, Sentence case turns NASA HELLO WORLD. NEXT LINE! into Nasa hello world. Next line!. The case change is mechanical: it does not know that NASA is an acronym. Correct names and abbreviations in the output before publishing.

Supported Inputs & Output Formats
| Type | Format | Details & Handling |
|---|---|---|
| Input | Plain Text | Any text, paragraphs, headings, lists, or articles requiring capitalization correction. |
| Output | Formatted Text (.txt) | Clean converted text formatted according to your selected case mode, available to copy or download. |
Common Practical Use Cases
- Fix ACCIDENTAL CAPS LOCK: Convert entire paragraphs typed in all-caps back into clean, readable sentence case.
- Format Headings & Titles: Apply title case to blog post titles, newsletter headings, and presentation slides.
- Standardize Lists & Names: Capitalize each word in contact lists, spreadsheet columns, and product catalogues.
Important Limitations & Technical Boundaries
- Generic Title Case Rules: Uses a general-purpose title case algorithm with a standard minor-word exclusion list. It does not provide specialized rule toggles for AP, Chicago, APA, or MLA style guides.
- Proper nouns and acronyms: Sentence case and Title Case lowercase their input before capitalizing selected words, so names such as NASA may become Nasa.
- Client-Side In-Memory: All transformations run in your browser session without storing history or sending data to a backend.
Frequently Asked Questions
What capitalization modes does the Text Capitalizer support?
It supports five modes: Sentence case (capitalizes the first letter of each sentence), Title Case (capitalizes major words while keeping common minor words lowercase), Capitalize Every Word (capitalizes the first letter of all words), UPPERCASE (converts all letters to upper case), and lowercase (converts all letters to lower case).
How does Title Case differ from Capitalize Every Word mode?
Title Case keeps common minor words (such as "in", "on", "at", "and", "or", "the", "a") in lowercase unless they are the first or last word of a line. Capitalize Every Word capitalizes the initial letter of every single word without exception.
Can this tool fix all-caps text into normal sentence case?
It lowercases the input, then capitalizes the first character and letters after sentence punctuation followed by whitespace. Select Sentence case and click Run. Proper nouns and acronyms such as NASA will need manual correction.
Does Title Case follow a specific style guide like AP or Chicago?
The tool uses a practical general-purpose title case algorithm that capitalizes major words and lowercases standard short conjunctions, articles, and prepositions. It does not provide individual toggle switches for specific publication stylebooks.
Is my text processed securely on my device?
The conversion runs in your browser using JavaScript string methods. The tool does not submit the entered text for conversion; see the privacy policy for site analytics and ads.
Can I process multiple lines or paragraphs at once?
Yes. The capitalizer processes multi-line text and multiple paragraphs simultaneously, preserving your line breaks and spacing.
