What Is the Underline Text Generator?
The Underline Text Generator is a free online tool that lets you add a combining underline to your text. It runs entirely in your browser — your text and files never leave your device, so it's fast and private. There's nothing to install and no sign-up required.

Using the Underline Text Generator takes seconds. Paste or type your content into the input area (or upload a file where supported), adjust any options to fit your needs, and the result updates instantly. You can then copy the output to your clipboard, download it, or clear everything and start again. Because all processing happens locally with JavaScript, it works offline once the page has loaded.
