Upper- and lowercase letters have separate circled forms.
10 characters · 10 UTF-16 units
Letters become uppercase. Zero and 1–9 come from different Unicode groups, so their size may differ.

Some filled circles appear as emoji on a device. No colour setting is copied with them.
Two circle families with different case rules
The hollow result uses circled Latin letters and circled digits. Its A and a are distinct characters. Filled circles use negative circled capital letters, so a lowercase a becomes the same character as uppercase A. The case control changes ordinary Latin letters only; it leaves accented letters, other languages and emoji untouched.
Why zero can look smaller than one
There is no single continuous filled alphabet-and-digits set. The letters are in Enclosed Alphanumeric Supplement, 1–9 use dingbat negative circled digits, and zero is U+24FF, Negative Circled Digit Zero. A receiving font may draw those groups with different diameters or baseline positions.
Keycap emoji such as 1️⃣ stay intact. This tool does not add an emoji presentation selector or force a circle’s colour. If the filled version becomes a box or coloured symbol in an app, try the hollow version or ordinary text.
Circle a short name, not an account handle
Bubble letters can work as a short display-name flourish, heading or caption. Use ordinary text for a searchable handle and a plain companion name for accessibility. Every circle is a new character rather than an outline applied to the original letter. The font mixer can circle just one word while leaving links alone.
If you meant outlined double-stroke letters such as 𝕒 rather than circles, choose Double struck in the fancy text comparison. These are different alphabets, not interchangeable bubble styles.
Frequently asked questions
Can bubble letters be pasted as editable text?
Yes, the results are characters, not pictures. Whether they render or are accepted depends on the destination app and its field rules.
Can I recover lowercase from filled bubbles?
No. Both A and a become the same filled capital letter. Undo or keep your original text if its capitalisation matters.
