Frequently Asked Questions

What is Title Case vs Proper Case?

Title Case typically capitalizes major words while keeping minor words (like 'and', 'the', 'of') lowercase, ideal for headlines. Proper Case capitalizes the first letter of every single word.

How does Sentence Case work?

Sentence Case capitalizes only the first letter of the first word in each sentence, making it perfect for correcting text that was accidentally typed in all caps.

What is iNVERT cASE used for?

iNVERT cASE flips the capitalization of every letter. It's commonly used for creative effects, social media posts, or fixing text where someone accidentally toggled caps lock mid-sentence.

Can I upload a file to convert?

Yes! Click the Upload icon in the Input Text section to load a .txt file (up to 1MB). The tool will automatically convert the entire file content.

How do I fix text stuck in ALL CAPS?

Paste your ALL CAPS text, then select 'Sentence case' to convert it to normal capitalization. This will capitalize only the first letter of each sentence.

Does this work with Unicode and emojis?

Yes, the tool supports Unicode characters including accented letters (é, ñ, ü) and preserves emojis and special characters while converting the text case.

Is there a character limit?

There's no strict character limit. The tool processes text entirely in your browser, so limits depend on your device's memory. Most users can easily convert documents with millions of characters.
