Text Case Converter

About This Tool

This case converter lets you change the capitalization of any text with one click. Paste your text, pick a format, and the result appears instantly in the same box — ready to copy.

What each format does

• UPPERCASE — converts every letter to capitals. Useful for headings, labels, or emphasis.
• lowercase — converts every letter to small. Useful for cleaning up text typed with caps lock on.
• Sentence case — capitalizes only the first letter of each sentence. Good for fixing copy-pasted text that lost its formatting.
• Title Case — capitalizes the first letter of each major word. Standard for article headlines, book titles, and headings.
• Capitalize Words — capitalizes the first letter of every word, including small words like "the" and "and". Useful for names and lists.

When would you use this?

• Someone sent you text in ALL CAPS and you want to make it readable.
• You're formatting a headline and need consistent title case.
• You're cleaning up data exported from a spreadsheet or database.
• You need to match a specific capitalization style for a document or website.

Title Case vs. Capitalize Words — what's the difference?

Title Case follows standard editorial rules — it skips capitalizing small connecting words like "a", "the", "and", "of", and "in" when they appear in the middle of a title. Capitalize Words capitalizes every single word without exception. For most article or blog headlines, Title Case is the conventional choice.
