Can you bold text in an Instagram bio?

Not with any built-in setting, since Instagram has no formatting toolbar. You paste Unicode bold characters instead, which is what this tool creates for you.

Why do my hashtags stop working when I bold them?

The bold letters are different characters from the plain ones, so a tag like #sale becomes a string Instagram no longer recognizes as a hashtag or handle. Keep every hashtag and mention in plain letters.

Why does my bold bio show empty boxes on some phones?

Those phones have a font without the Unicode math glyphs, so they fall back to placeholder boxes. Preview on a real device, and keep bold to a short phrase so a fallback is less jarring.

Common gotchas

Instagram has no formatting controls anywhere, so bold in a bio or caption can only be faked with the Unicode glyphs this tool outputs.
Bolding a hashtag or @mention turns its letters into different characters, so the tag is no longer clickable or searchable. Always leave #tags and handles in normal letters.
Instagram is mostly used on phones, and a small share of devices lack these math glyphs and show blank boxes, so preview your bio on a phone before you save it.
These glyphs read poorly to screen readers and are not indexed as plain text, so do not bold your whole bio or your searchable keywords.
