What is the Text Case Converter?
A text case converter instantly changes the capitalization of any text — to UPPERCASE, lowercase, Title Case, sentence case, and more. Everyone has hit Caps Lock by accident and typed a paragraph in all caps; everyone has also pasted a heading in the wrong style for a document or title tag. Fixing these by hand is tedious and invites missed letters, especially in long passages.
On BConvert, conversion is instant as you type. Paste your text, pick the target case, and the result updates live with word and character counts alongside. Extra cleanup helpers strip double spaces and stray line breaks. It all runs in your browser, so private drafts and sensitive notes never leave your device.
How to use it
- Paste your text — Paste or type your text into the input box — articles, headings, code, or whole paragraphs all work.
- Choose the case — Pick the target case: UPPER, lower, Title Case, Sentence case, aLtErNaTiNg, or inverted.
- Watch it update live — Watch the result update live as you type, with character and word counts alongside.
- Clean up whitespace — Use the extra tools to remove extra spaces or line breaks if your pasted text is messy.
- Copy or download — Copy the converted text with one click or download it as a text file for later use.
Common use cases
- Fix an entire paragraph accidentally typed with Caps Lock on before sending an email.
- Normalize spreadsheet column headers to Title Case for a cleaner-looking report.
- Convert headings to sentence case to match a publication's editorial style guide.
- Reformat pasted code comments or constants between upper-snake and lower-snake conventions.
Tips
- Title Case capitalizes small words too — review words like and, the, and of manually for strict style guides.
- Sentence case only fixes the first letter; it will not repair mid-sentence capitalization errors.
- Use the remove-extra-spaces option after converting pasted web text to clean up double spacing.
- For code, convert first then run your formatter — case tools do not understand syntax.

Is my pasted text sent anywhere?

Does Title Case handle apostrophes correctly?
Yes — words like don't and O'Brien are treated as single words, so the letter after the apostrophe is not wrongly capitalized.
