About the Lowercase Converter
Typed a whole paragraph with caps lock on? Need to normalise email addresses, tags or usernames so they can be compared? This converter turns every capital letter into its lowercase form.
Conversion follows Unicode rules, so letters with accents and letters from other alphabets are handled correctly. Everything else, including numbers, punctuation and line breaks, stays the same. To make the result read like normal sentences again, you can follow up with the Title Case Converter for headings.

Frequently asked questions
Are email addresses case-sensitive?
The domain part is not, and in practice most mail providers treat the whole address as case-insensitive, which is why lowercasing is a common clean-up step.
Does it change numbers or symbols?
No, only letters.
Can I convert back to the original capitals?
No. The original capitalisation is not stored, so keep a copy of your text if you may need it.
Is the text I enter kept private?
Yes. The Lowercase Converter runs entirely in your web browser, so your text is never uploaded to or stored on our servers. Like most free websites, TextForge shows ads from Google, which may use cookies. See our Privacy Policy for details.
