What this tool is for
Capitalized case (also called start case) puts a capital on the first letter of every word and lowercases the rest of that word. It is heavier than title case because small words like “Of,” “And,” and “The” are capitalized too. Product teams use it for short labels more often than publishers use it for headlines. This page is for tidying a list of feature names, form legends, or button-style phrases that your design system wants in Start Case.
How it works
The converter lowercases the whole string, then capitalizes every character that matches a word boundary followed by a word character (`\b\w`). A hyphen is a non-word character, so it creates a new boundary: “e-commerce” becomes “E-Commerce,” not “E-commerce.” Line breaks are kept; the letter after a newline is capitalized when it is a word character. Digits and punctuation stay where they are. There is no small-word list and no dictionary of brands or acronyms.
When to use it
Button and menu labels in a design system that specifies Start Case (“Save Changes”), spreadsheet column headers, form legends, short display names, and feature lists copied in lowercase. It is a fast way to make every word look intentional when title case would leave “of” and “the” small and you do not want that.
When not to use it
Do not run long article titles through capitalized case if your house style wants title case with small words left lowercase. Do not convert body paragraphs — every line will look like a label. Do not use it for programming identifiers (prefer camelCase or PascalCase). Do not expect “XML,” “iPhone,” or “NASA” to survive: the whole string is lowercased first, so acronyms become “Xml” and “Nasa.”
How it compares to related tools
Title case leaves a fixed list of minor words lowercase in the middle of a heading and treats hyphenated tokens as one word (“E-commerce”). Sentence case only capitalizes sentence starts — that is for emails and article bodies. Upper case shouts the whole string. PascalCase removes spaces. If Caps Lock inverted letters (hELLO), run Inverse Case first.
Common mistakes
Shipping a twenty-word blog title with every “Of” and “The” capitalized when the style guide wanted title case. Converting “iPhone” or “XML” and wondering why the brand spelling disappeared. Treating capitalized case as Chicago or APA title case. Pasting live URLs: letters inside the path are lowercased then re-capitalized at each word boundary.
Start case versus publishing title case
Start case / capitalized case is common in older desktop UIs and in some spreadsheet cultures: every word looks “finished.” Modern product writing often prefers sentence case for buttons (“Save changes”) because it is quieter and matches body text. English blog titles usually follow title case, which keeps short function words lowercase in the middle. Pick the pattern your design system names, convert a whole list here in one paste, then fix brands by hand.
Hyphens, newlines, and empty input
Because the engine uses `\b\w`, a hyphen splits “e-commerce” into two capitalizable units. Apostrophes and other punctuation can also create boundaries depending on the surrounding characters. Newlines are not removed — “hello\nworld” becomes “Hello\nWorld.” Empty input produces empty output. The converter does not trim spaces; it only changes letter case at word boundaries after the global lowercase pass.
Frequently asked questions
Is capitalized case the same as title case?+
No. Title case usually keeps short articles and prepositions lowercase in the middle of a title. Capitalized case capitalizes every word, including “Of” and “The.”
Why did “e-commerce” become “E-Commerce”?+
The converter capitalizes after each word boundary. A hyphen is not a word character, so “commerce” is treated as a new word. Title case on this site treats the hyphenated token as one word and yields “E-commerce.”
Should menu items use this style?+
Follow your design system. Many products use sentence case for menus (“Save changes”). Capitalized case (“Save Changes”) is common in older desktop software and some B2B UIs.
Does this preserve acronyms like HTML or NASA?+
No. The string is lowercased first, then each word’s first letter is raised. “HTML” becomes “Html.” Restore acronyms and brand spellings after conversion.
Is my text uploaded?+
No. Conversion runs in this browser. Nothing is sent to a server to transform the text.

Title Case Converter
Format blog post titles, slide decks, README headings, newsletter subject lines that your brand treats as titles, documentation section names, and book or article titles in English. It is faster than retouching twenty headings by hand after a draft in sentence case. Convert the heading list; leave the article body in sentence case.
Sentence Case Converter
Use it on emails typed with Caps Lock, meeting notes from a phone, support tickets, OCR from a PDF, and blog drafts that went through an uppercase filter. It is the right tool when the destination is a paragraph, a message, or a UI sentence — not a headline. Product copy, error messages, and documentation body text almost always belong in sentence case because it is easier to scan than a wall of capitals.
Upper Case Converter
Warning banners, warehouse and packing labels, form section names that a design system specifies in caps, crossword-style puzzles, matching a legacy field that stores values in uppercase, and preparing a short line that must be visible at a distance. Keep the string short. A five-word label in caps can work; a paragraph will not.
Lower Case Converter
Preparing tags, normalizing CSV columns, turning a headline into input for a slug generator, lowercasing identifiers before a further snake_case or kebab-case conversion, and calming an accidental Caps Lock paragraph when you do not need sentence capitals yet. Also useful when two systems disagree about case and you need a single canonical form for comparison.
Inverse Case Converter
Rescuing a paragraph typed with Caps Lock and Shift, reversing alternating-case jokes, checking how a UI looks with inverted labels in a fixture, and fixing a short paste before you apply sentence case for readable prose.
