An invisible character is a real Unicode character that can look blank on screen while still counting as text. Some characters take no visual space at all, such as Zero Width Space (U+200B). Others create a blank-looking area, such as Hangul Filler (U+3164), Braille Pattern Blank (U+2800), and wider Unicode spaces.
This page lets you copy those characters quickly, paste them into your own app, and test whether the pasted output is still present. Use it for formatting, spacing, aesthetic bios, captions, blank-looking messages, usernames, layout testing, and Unicode compatibility checks.
For focused guides, see the invisible text tool, the invisible character guide, the blank text tool, the blank space characters, or the invisible text generator.
Using the tool is simple, but testing matters because each app handles Unicode differently:
There is no single best invisible character for every situation. Start with the result you want, then test it in the app where you plan to paste it.
Best when you need a character that usually has no visible width. It is useful for Unicode testing, blank-looking fields, and subtle separators.
Best for blank-looking display-name tests because it is a real Unicode character with a stronger presence than a zero-width mark. Some apps preserve it, while others may remove or display it differently.
Best for a blank-looking character that occupies visible space. It is often useful for profile formatting, blank-looking messages, and layout tests.
Use No-Break Space, En Space, Em Space, Thin Space, Hair Space, or Ideographic Space when you want controlled spacing rather than a fully invisible character.
Invisible Unicode characters are normal text characters, but apps do not all treat them the same way. A character may copy correctly and still be changed after you paste it.
