Common use cases

Headlines and blog titles

Paste a draft title and apply Title Case (or Sentence case) so every heading follows the same style.

Undoing caps lock

Convert a block typed in ALL CAPS to lowercase or Sentence case in one click.

UI labels and constants

Quickly produce UPPERCASE labels or lowercase identifiers when prototyping copy or config values.

Social and ad copy

Normalize casing before checking character limits so shouty drafts become readable posts.

Examples

• Title Case (headline): "hello world" becomes "Hello World" - great for titles and headings.
• UPPERCASE: "warning" becomes "WARNING" for emphasis or labels.
• lowercase: "HELLO THERE" becomes "hello there" to undo accidental caps lock.
• Sentence case: "the quick brown fox" becomes "The quick brown fox".

Pro tips

• Title Case here capitalizes each word - it is not APA/Chicago "small word" title case; tweak short words manually if your style guide requires it.
• Sentence case only capitalizes the first letter of the whole string - re-run per sentence if you paste multiple sentences.
• Case conversion does not change spacing; pair with Remove Extra Spaces for messy paste jobs.
• For URL-safe paths, use Slug Generator instead of lowercase alone.
• After converting a title, run Character Counter if you are fitting a SERP title or social limit.

Frequently asked questions

What is the difference between the case styles?

UPPERCASE makes every letter a capital. lowercase makes every letter small. Title Case capitalizes the first letter of each word (good for headings). Sentence case capitalizes only the first letter of the text, like a normal sentence.

What is sentence case?

Sentence case capitalizes the first letter of the text (and leaves the rest lowercase), just as you would write a normal sentence. For example, 'the report is ready' becomes 'The report is ready'.

What is title case?

Title case capitalizes the first letter of each word, which is the common style for headlines and titles - for example 'a tale of two cities' becomes 'A Tale Of Two Cities'. It is a simple word-by-word capitalization rather than a strict style-guide title case.

Does converting case change my words or punctuation?

No. Only the capitalization of letters changes. Your words, numbers, punctuation, spacing, and their order all stay exactly the same.

Is my text sent to a server?

No. All conversion happens in your browser with JavaScript, so nothing you paste is uploaded, logged, or stored.
