A free online case converter that transforms your text into all 8 formats simultaneously — camelCase, PascalCase, snake_case, kebab-case, UPPER CASE, lower case, Title Case and Sentence case. Paste once, copy the format you need. Runs entirely in your browser — no data is sent to any server.
Paste your text into the case converter
Type or paste any text into the input field on the left. The converter accepts plain text of any length — code identifiers, sentences, headings or raw data.
The converter detects word boundaries automatically
Spaces, hyphens and mixed capitalisation (like camelCase or kebab-case) are all recognized as word separators, so you can paste text already in one code format and get accurate results in every other format.
See all 8 formats instantly
Results appear in real time across all 8 case formats simultaneously — no need to select a format before converting.
Click any result to copy
Click the card of the format you need — the converted text is copied to your clipboard immediately. A checkmark confirms the copy.
A case converter transforms text between different capitalisation styles. This tool supports 8 formats: UPPER CASE, lower case, Title Case, Sentence case, camelCase, PascalCase, snake_case and kebab-case — all converted simultaneously from a single input.
This tool converts pasted text into camelCase and snake_case instantly, alongside 6 other formats. Click either result card to copy it — the converter treats spaces, hyphens and mixed capitalisation as word separators automatically, so it also works on text that's already in some code-case format.
camelCase starts with a lowercase letter and capitalises each subsequent word (helloWorld). PascalCase capitalises every word including the first (HelloWorld). snake_case joins words with underscores in lowercase (hello_world). All three are common in programming.
Yes — this case converter is completely free, and all conversion happens locally in your browser. No text is ever sent to a server — the tool works fully offline and processes everything entirely on your device.
This converter correctly splits identifiers already written in camelCase, PascalCase, snake_case or kebab-case before re-formatting them. That makes it reliable for renaming variables and functions across different coding style conventions, even when the input is already in code-case.
Yes — clicking Load example fills the input with a short lowercase phrase. All 8 case-format cards update immediately, so you can see the same words rendered as UPPER CASE, camelCase, snake_case and every other format at a glance.
