Free Text Case Converter that works offline
The text case converter changes capitalization and naming style in one click. Turn a heading into title case, normalize accidental uppercase text, or create camelCase, snake_case and kebab-case identifiers for code and URLs.
What this text case converter does
Capitalization rules serve different contexts. Sentence case is common in interface copy, title case is useful for headings, and machine-friendly styles remove spaces to create identifiers. This converter keeps the original text in the input panel and writes the transformed version separately, making it easy to compare before copying.
How to use the Text Case Converter
- Paste the source text into the left editor.
- Choose the target style from the conversion buttons.
- Review the converted text in the result panel.
- Copy the result, or choose another style without re-pasting the source.
Common uses
- Repairing content accidentally typed with Caps Lock
- Standardizing headings and interface labels
- Creating JavaScript-style camelCase variable names
- Producing snake_case database fields or kebab-case URL fragments
Private processing and offline access
This tool does not submit your input to a conversion server. Processing takes place inside the browser using local JavaScript and standard Web APIs. After the PWA has been installed or cached, the page and its core features remain available without an internet connection. Closing or clearing the page removes unsaved input; the tool does not create an account or cloud history.
Tips for accurate results
- Automated title case cannot know every brand’s preferred capitalization, so proofread proper names.
- Identifier modes remove punctuation and accents to create predictable machine-friendly output.
- Sentence case works best when sentences end with conventional punctuation.
