Sentence Case tips

📝

Sentence case makes text more readable than all-caps or all-lowercase. Great for cleaning up pasted content.

✍️

Got text in ALL CAPS from a PDF or database export? Convert to sentence case for a normal, readable format.

📧

Use sentence case for email body text, chat messages, and informal writing. It sounds natural and friendly.

💡

The converter detects sentence boundaries by punctuation — periods, exclamation marks, and question marks.
