Frequently Asked Questions
What is title case?
Title case capitalises the first letter of most words. Minor words like "and", "the", "in", "of", "at", "by", "a", "an", "but", "or", and "for" stay lowercase unless they appear at the very start of the title. This tool follows standard title case rules used in publishing and journalism.
What is sentence case?
Sentence case capitalises only the first word of each sentence and proper nouns. All other words remain lowercase. It is used for most body text, social media captions, email subject lines, and general writing. Click "Sentence case" to fix ALL CAPS text instantly.
How do I convert ALL CAPS to normal text?
Paste your text and click "Sentence case". This converts every letter to lowercase and then capitalises only the first letter of each sentence, restoring normal readable text. For headings, "Title Case" may be more appropriate depending on context.
Does this work for multiple paragraphs?
Yes. Paste any amount of text and all six case conversions work across the full input including line breaks, punctuation, and multiple paragraphs. Character counts update instantly for both input and output panels. Use the "Remove line breaks" option to collapse paragraphs into a single block if needed.
