Tus archivos nunca salen de tu dispositivo.
Paste a line or a whole paragraph and switch it between case styles in one click — no retyping a heading you accidentally left in caps, no hand-editing every separator to turn a label into a code identifier. The converter splits your text on spaces, punctuation, and existing case boundaries, then rejoins it in the style you pick.
Every style, applied to "hello world example"
| Style | Result | Typical use |
|---|---|---|
| UPPERCASE | HELLO WORLD EXAMPLE | Emphasis, headings |
| lowercase | hello world example | Normalising input |
| Title Case | Hello World Example | Titles, headlines |
| Sentence case | Hello world example | Body prose |
| camelCase | helloWorldExample | JS / Java variables |
| snake_case | hello_world_example | Python, SQL columns |
| kebab-case | hello-world-example | CSS classes, URL slugs |
It splits at case transitions too, so an existing camelCase input is broken back into words before being rejoined in the new style.
Frequently asked questions
- Title Case vs Sentence case?
- Title Case capitalises the first letter of each significant word (headline style); Sentence case capitalises only the first word plus any proper nouns (ordinary prose). The reference row for each shows exactly how the same phrase differs.
- Does Title Case follow AP/Chicago rules about small words?
- It capitalises the first letter of each word. Formal style guides leave short articles and prepositions like 'a', 'the', and 'of' lowercase; if you need that exact treatment, do a quick manual pass after converting.
- Is my text uploaded anywhere?
- No. Conversion is pure JavaScript in your browser, so names, labels, and unpublished copy never leave your device.
