About this tool

What is Case Converter?

A case converter changes the capitalization of text between different formats. The most common conversions are UPPER CASE (all capitals), lower case (all lowercase), Title Case (First Letter Of Each Word Capitalized), and Sentence case (Only the first word capitalized). Each has different uses and contexts where it's the correct choice.

Textora's free case converter handles all major formats in one click. It's faster than selecting text and applying manual formatting, and it avoids the errors that come from trying to manually capitalize or decapitalize large amounts of text — missing a word, or leaving a capital where it shouldn't be.

Common questions

Frequently Asked Questions

Is the case converter free?
Yes — instant, no account required, no limits.
What case formats does it support?
UPPER CASE, lower case, Title Case, Sentence case, and alternating case. All common use cases are covered.
What is Title Case?
Title Case capitalizes the first letter of every major word. Most style guides have rules about which words to capitalize — typically excluding short prepositions, articles, and conjunctions.
What is the difference between Sentence case and Title Case?
Sentence case only capitalizes the first word of each sentence plus proper nouns. Title Case capitalizes the first letter of most every word. Sentence case is used in prose; Title Case is used in headlines and headings.
Does it work on programming code?
For source code identifiers, use the developer-focused case options. Converting code that mixes syntax and content may produce unexpected results.
Is there a character limit?
No. Paste any length of text.
