Frequently Asked Questions (FAQ)
This is a key distinction. Title Case follows specific rules, capitalizing major words (like nouns, verbs, and adjectives) but typically not minor words (like "a", "an", "the", and "and") unless they are the first or last word. Capitalize Text (or "Capitalize Each Word") simply makes the first letter of every word uppercase, regardless of grammar rules. Title Case is suited for professional titles, while Capitalize Text works better for stylistic lists or labels.
You would use the "Sentence case" converter. This format is designed specifically to lowercase all letters except the first letter of the first word in a sentence, which it capitalizes. It is the ideal tool for fixing text that was typed with the CAPS LOCK key on.
Yes, both applications have built-in case-changing functions (under the "Format" menu or via a shortcut like Shift + F3). However, an online converter like ours is often faster for batch processing, offers more specific formats (such as strict Title Case), and allows easy import and export without opening a document.
No, a proper case converter only affects alphabetical letters (A-Z). It leaves all numbers, symbols, punctuation marks, and special characters completely untouched, preserving the integrity of your original content.
Several major style guides exist (APA, MLA, Chicago, AP). Their rules for title cases differ slightly, particularly regarding which short words to capitalize. Most online tools, including ours, follow a commonly accepted standard. For strict academic or publishing work, you should verify the output against your required style guide.
