About this tool
This tool is for adding a strikethrough, underline or overline effect to text on platforms that don't support real text formatting, like most social media bios, chat apps and comment sections — it works by inserting an invisible Unicode "combining" character after every letter, which your device renders as a line through, under or over the text.
How to use it
- Type your text into the box.
- Pick the effect you want: strikethrough, underline, double strikethrough or overline.
- Click "Copy" and paste the result anywhere.
Frequently asked questions
Will this work on Instagram, Twitter/X and other social apps?
Yes, in most cases — since it's made of real Unicode characters rather than formatting, it displays correctly in bios, posts and comments on the vast majority of platforms.
Why does the line sometimes look uneven or overlap oddly?
Combining characters stack on top of the previous letter rather than being measured and spaced like normal formatting, so the exact look can vary slightly between fonts, apps and operating systems.
Can I undo this if I paste it somewhere by mistake?
Yes — just delete the pasted text and retype it normally, or paste the original plain text again. The styled version doesn't affect anything other than how that specific text displays.
