Technical patterns
Your text is converted locally and never leaves this browser.
Paste text and pick a case style to convert it.
How it works
- Paste the source text you want to standardize.
- Choose the case style that fits the destination.
- Copy the derived result while keeping your source text intact.
When translators use it
Standardize headings, UI strings, file names, and glossary entries.
What to know
Case rules vary by language; scripts without upper and lower case stay unchanged.
