Add a real strikethrough, underline, double-strike or slash mark to any text using Unicode combining characters, so it works even where HTML tags don't.
Every mark added by this tool is a genuine Unicode combining character attached to your text, so the effect survives copy and paste into apps that strip formatting.
Strikethrough, underline, double-strike and slash-through, switchable in one click.
Whitespace is always skipped, so the marks never look broken between words.
The result is plain Unicode text that pastes cleanly into bios, chats and posts.
Native HTML gives designers a simple way to strike through text with the <s> tag or a CSS text-decoration rule, but that only works where HTML and CSS are actually rendered. The moment text leaves a web page, whether pasted into a social media bio, a group chat, a spreadsheet cell or a plain-text comment box, all of that formatting disappears, because the platform only ever sees plain characters. Unicode combining characters solve this by making the strike mark part of the text itself rather than a decoration applied on top of it. This tool inserts one combining character immediately after every visible letter you type: U+0336 draws a long stroke through the character for classic strikethrough, U+0332 draws a low line beneath it for underline, U+033F draws two overlapping lines through it for double-strike, and U+0335 draws a short diagonal stroke for slash-through. Because each mark attaches to the character before it, the visual effect lines up correctly even as you keep typing, and the tool deliberately skips inserting a mark after spaces so the line doesn't visibly break or look disconnected between words.
A long stroke overlay drawn straight through the middle of each letter.
A low line combining mark drawn directly beneath each letter.
Double overline for a bold double-strike, short solidus for a diagonal slash.
It inserts a Unicode combining character directly after every visible letter in your text. The mark attaches to the character before it, so the strike, underline or slash appears to run through your actual text rather than being a separate decoration.
Most social media bios, chat apps and comment boxes strip HTML tags entirely, so an <s> tag would never render. Unicode combining characters are just plain text characters, so the strikethrough effect survives copy and paste anywhere.
Strikethrough draws a single line through the middle of each character, underline draws a line beneath it, double-strike draws two overlapping lines through it, and slash-through draws a diagonal slash across it.
In most cases yes, since the result is standard Unicode text. Rendering quality can vary slightly by font and platform, and a few apps may not display combining characters at all.
Yes. Conversion happens instantly in your browser using plain JavaScript, and your text is never uploaded or stored.
