When sentence case helps
Text from caps-lock typing, scanned documents or old databases often comes in ALL CAPS, which is tiring to read. A sentence case converter brings it back to normal — a capital letter to start, lowercase for the rest — so it reads like ordinary prose.
The tool lowercases everything and capitalizes sentence beginnings, but because it works from punctuation it cannot re-capitalize proper nouns like names, cities or brands. After converting, scan for words like London or iPhone and fix them by hand.
Local and private
Conversion is a simple string transform that runs entirely in your browser, so your text is never uploaded and no sign-up is needed. It changes only the case and formatting, never the actual words.
Frequently asked questions
How do I fix ALL CAPS into normal text?
Paste the text, choose Sentence case, and the tool lowercases it while capitalizing the start of each sentence.
Does it re-capitalize names and places?
No. It capitalizes sentence starts only, so proper nouns like names or brands may need a manual fix afterwards.
What is the difference from Title Case?
Sentence case only capitalizes the first word of each sentence, while title case capitalizes most words for headlines.
Is my text private?
Yes. It is processed in your browser with no upload and no account required.
Does it work offline?
Once the page has loaded, the conversion runs locally, so it keeps working without a connection.
