Frequently Asked Questions
Find quick answers to common questions about case conversion.
What is a case converter and what does it do?
A case converter is an online utility that transforms blocks of text between different letter casing formats. It allows you to instantly convert text into lowercase, uppercase, sentence case, title case, or developer formats like camelCase, snake_case, and kebab-case without having to retype the content manually.
Is my text sent to any server or database?
No. Case Converter | Voice to Text is a fully client-side application. Every case conversion, text cleanup, search and replace, or speech synthesis runs natively in your browser using JavaScript. No text is ever uploaded to any database, ensuring absolute privacy for sensitive documentation.
How does the Title Case algorithm handle special words?
Our Title Case converter matches standard style rules (like APA and Chicago manuals). It capitalizes the first and last words of the title, along with all nouns, verbs, pronouns, adjectives, and adverbs. Common articles (a, an, the), prepositions (in, of, to), and conjunctions (and, but, or) remain lowercase.
Can I drag and drop text files?
Yes! You can drag and drop any plaintext file (like `.txt`, `.md`, `.json`, etc.) directly into the editor. The app will immediately load and display the contents so you can apply the conversions and download the updated version.
Is there an undo / redo limit?
The editor tracks up to 50 previous versions of your text changes. You can trigger undo and redo using the interface buttons or standard keyboard shortcuts (`Ctrl+Z` and `Ctrl+Y`).
