Underline Text Generator
Underline, double underline, wavy underline and the full strike-through family.
Underlining is the oldest emphasis trick in writing, and Unicode lets you take it anywhere. This generator adds a clean underline, a double underline or a wavy underline beneath every character, and includes the related strike family — strikethrough, slash and tilde strikes — for edits, jokes and corrections.
Because the marks are part of the text itself, the emphasis survives copy and paste into bios, documents and posts where normal formatting buttons do not exist. Type once and compare every line style together.

Frequently asked questions
Does underlined text paste into Instagram?
Yes — the underline is a combining character inside the text, so it appears in bios and captions without any formatting feature.
What is wavy underline used for?
It reads as playful or informal emphasis — great for quotes, nicknames and light-hearted posts.
Can I underline only one word?
Yes — generate the word here, then paste it into the middle of your normal sentence.
