FAQ
Questions people ask
Quick answers for the most common bold‑text questions.
Does this add real formatting?
It converts letters into Unicode bold characters, so the bold look stays even in plain text fields.
Why does it look thinner on some phones?
Rendering depends on the device font. Try another bold style for a heavier look.
Can I mix bold and normal text?
Yes—bold a headline or label, then keep the rest plain for readability.
Is there a limit on text length?
Shorter lines read better, but you can convert any length of text.
Why do some accents stay normal?
Some styles don’t include every accented character. Use a different style or simplify the text.
