How to convert text case
- Paste your text into the box.

- Press Copy text and paste it back where you need it.
When to use each case
- Sentence case: normal writing, emails, and fixing text typed with caps lock on.
- Title Case: headings, book and article titles.
- UPPERCASE: short labels and signs. Long uppercase text is hard to read and reads as shouting.
- lowercase: tags, usernames and web addresses.
Frequently Asked Questions
How do I change all caps to lowercase?
Paste your text and press lowercase. To keep capitals at the start of each sentence, press Sentence case instead.
What is the difference between Title Case and Sentence case?
Title Case capitalises the first letter of every word ("How To Write A Letter"), as in book and film titles. Sentence case capitalises only the first word of each sentence and the word "I" ("How to write a letter").
Will it fix names and acronyms?
No tool can know which words are names or acronyms, so Sentence case and lowercase make them lowercase too. Check names like "Dhaka" or "NASA" after converting.
Does it work with other languages?
Yes, for any language with upper and lower case letters, including accented letters like é and ü. Scripts without case, such as Bangla, stay as they are.
