Questions
FAQ
What is a case converter?+
A case converter changes capitalization without rewriting your words. Use it for headlines, legal captions, code identifiers, or posts that arrived in the wrong case.
How do I use Case Studio?+
Type or paste in the field, then press a case. Import a .txt file if the copy already lives on disk. Copy puts the result on your clipboard; Download saves a text file.
What is the difference between Title Case and Sentence case?+
Sentence case capitalizes the first letter of each sentence, the way body copy reads. Title Case capitalizes major words and leaves short glue words (a, the, of, and) small — except at the start or end of a line.
Do you store my text?+
No. Conversion runs in your browser. A local draft is kept only on this device so a refresh does not wipe the editor. Nothing is sent to a server.
What are the fancy fonts?+
They are Unicode lookalikes — mathematical bold, script, gothic, circled letters — that paste into X, Instagram, Discord, and Facebook. They are not installable typefaces.
Can I convert a file?+
Yes. Import accepts plain-text files up to 2 MB. Download writes the current editor contents as case-studio.txt.
