Is this invisible character tool free?

Yes. It is free with no sign-up. Copy one character, generate up to 1,000 repeated characters, and inspect pasted text in your browser.

Which characters are really invisible?

Zero Width Space U+200B, Zero Width Non-Joiner U+200C, Zero Width Joiner U+200D and Word Joiner U+2060 have no visible glyph or width by themselves, although joiners can affect neighbouring letters and emoji. Braille Pattern Blank U+2800 and Hangul Filler U+3164 render as blank space with width in fonts that support them.

Is my text uploaded or stored?

No. Generated text and text pasted into the tester are processed in your browser tab. This tool does not upload, store or share them.

Will invisible text work in every game or social app?

No. Platforms can strip, block, normalize, reject or change how they handle these Unicode characters at any time, and some fonts or screen readers behave differently. Test in the destination and follow that platform's rules.

Why is U+FE0F not offered as a blank character?

U+FE0F is Variation Selector-16. It modifies the character or emoji before it and is not blank text by itself, so this tool does not pretend it is a standalone invisible character. The tester will still label it when it appears in pasted text.
