How to use it
- Type or paste your post.
- Select the words to format, then tap a style in the toolbar: bold, italic, strikethrough, underline, gothic, script, squared or circled. With nothing selected, the whole text is formatted.
- Tap strikethrough or underline again to remove it, or “Tx” to make text plain again.
- Tap “Copy text” and paste it into Facebook, Instagram or WhatsApp.
How does it work? Facebook has no bold button for posts, so this tool swaps letters for look-alike Unicode characters that keep their style wherever you paste them.
Tip: screen readers may not read these characters well, so use them for a few words rather than a whole post.
Worked example
“Big news” in Bold becomes “𝗕𝗶𝗴 𝗻𝗲𝘄𝘀”, ready to paste into your post.
Frequently asked questions
Does bold text really work on Facebook?
Yes. The letters are separate Unicode characters rather than formatting, so they stay bold in posts, comments and your bio.
What is the character limit of a Facebook post?
Up to 63,206 characters. The counter under the box keeps track as you type.
Does it work on Instagram, WhatsApp, LinkedIn and X?
Yes, in most apps that accept plain text.
Why do some letters stay the same?
Unicode styles cover Latin letters and digits only. Accented letters and other alphabets stay as they are, but strikethrough and underline work on everything.
