FAQ
- Is this tool free?
- Yes, completely free with no usage limits, no account required, and no ads that block the tool.
- Does my text get uploaded to a server?
- No. All transformations run entirely in your browser using JavaScript. Your text never leaves your device, so it is safe for confidential or sensitive content.
- Does it work offline?
- Yes. Once the page is loaded, all features work without an internet connection. The site also supports installation as a PWA for offline-first use.
- What is the difference between Title Case and Sentence case?
- Title Case capitalizes the first letter of every word (e.g. "Hello World"). Sentence case capitalizes only the first letter of each sentence (e.g. "Hello world. Next sentence.").
- Can I remove duplicate lines from a list?
- Yes. Paste your list, click "Remove Duplicates", and any repeated lines are removed while preserving the original order of first occurrences.
