Good to know
Underline Text Generator works by adding a combining underline character after each letter, rather than a separate font. Rendering depends on the app, so the underline can look uneven or drop out on some systems. Only the first 2,000 characters are styled so the page stays responsive; a note appears when that limit is reached.
Frequently asked questions
How does the underline work?
It adds a combining underline mark to each character, so support depends on how the app renders combining marks.
Why does the underline look broken sometimes?
Combining marks render differently across apps and fonts, so the underline can appear uneven or missing on certain systems.
Will spaces be underlined?
The underline is applied per character; spacing and rendering vary, so check the result in your target app.
Is my text private when I use Underline Text Generator?
Yes. Underline Text Generator works locally in your browser, so your text never leaves your device.
