Text tool
Convert text between common writing formats and code-friendly case styles. Everything runs locally in your browser.
Example: Zażółć gęślą jaźń. hello world test
The conversion runs locally in your browser. Text is not sent to a ToolForge Online server.
The tool reads the text you paste or type, applies the selected case conversion, and writes the result on the page. Writing formats keep the original characters where possible, while separator-based formats split text into words and join them with a chosen separator.
Use it when you need an uppercase converter, lowercase converter, title case converter, sentence case converter, camel case converter, snake case converter or kebab case converter for everyday writing and simple technical naming.
The core conversion happens with browser JavaScript on your device. The tool does not require an account, upload text, or call an external text-processing service.
Title Case and Sentence case are practical formatting helpers, not academic language rules for every language. Review headings, names and formal text before publishing or sending them.
Paste “hello world test”, choose camelCase, and the result becomes “helloWorldTest”. Choose CONSTANT_CASE and the same text becomes “HELLO_WORLD_TEST”.
Lowercase, uppercase, sentence case, capitalize words and title case keep text content intact. Separator formats normalize spaces and punctuation into word boundaries, but they are designed not to drop whole words unexpectedly.

No. Lowercase and uppercase only change letter casing using browser text handling. They do not remove words, punctuation or Polish characters.
It is a practical formatting helper, not a perfect editorial rule for every language. It is useful for quick cleanup, but you should review formal titles manually.
Writing formats keep Polish letters such as ą, ć, ę, ł, ń, ó, ś, ź and ż. Code-friendly formats also keep Unicode word characters instead of forcing aggressive transliteration.
Yes. Convert text first, then use Copy result. If your browser blocks clipboard access, you can still select the result manually.
No account is required for this tool. The conversion output is generated in your browser page and is not uploaded to a ToolForge Online server for processing.
