Frequently asked questions
Which characters turn into bubble letters?
Bubble Letters convert A to Z, a to z and the digits 0 to 9. Black Bubble Letters convert letters and digits, using capital circles for lowercase letters. Square Letters and Black Square Letters convert letters to capital squares and leave digits unchanged. Accented letters, punctuation, other scripts and emoji stay as typed.
Is this a bubble font I need to install?
No. Bubble letters here are Unicode characters, so they paste as text into posts, bios, names and messages. How they look depends on the fonts of the device and app that show them.
Why do some bubble letters show as boxes or emoji?
A device without a font for these characters shows empty boxes instead. On some devices, the black square A, B, O and P appear as colored emoji. Check the result where you paste it.
Are bubble letters accessible?
Screen readers and search tools may read these characters differently from ordinary letters, or skip them. Keep important information in plain text.
Does the converter upload my text?
No. Conversion runs in your browser. The tool records interaction actions, not the text you enter.
