Questions about lowercase
More answers in the TextVix FAQ.
Should I lowercase email addresses?
Usually, yes. Email domains are case-insensitive and almost all providers treat the whole address that way, so lowercasing helps find duplicates.
How do I capitalize the first letter of sentences again?
Use Sentence case, which lowercases text and capitalizes the start of each sentence.
Is my text uploaded anywhere?
No. This tool runs entirely in your browser. Your text and files are never sent to a server or stored.
