Zero-Width Space Character Copy Tool

About the Zero-Width Space

The zero-width space (ZWSP), also known as a zero-width non-breaking space, is an invisible character in the Unicode standard. We created this simple tool so you can easily copy it and use it wherever you need. Unlike a regular space, it takes up no horizontal room, but it can be used to create line breaks or separate characters in places where you normally couldn't.

Why Use a Zero-Width Space?

This tiny, invisible character is surprisingly useful. You can use it in a bunch of creative ways:

• Claiming Usernames: Many social media sites see "user" and "us​er" (with a zero-width space) as different usernames. If your desired name is taken, you can sometimes add one of these to get a visually identical name that is still unique.
• Breaking Up URLs: If you need to write out a long URL in a document or message but don't want it to become a clickable link, you can put a zero-width space after the "https://" part. Most systems won't recognize it as a link anymore.
• Formatting Text: In some apps like Discord or TikTok, you can use zero-width spaces to create "empty" messages or format your profile bio in ways that aren't normally allowed.
• Bypassing Simple Word Filters: You can break up a word that might be blocked by a basic filter. For example, `f​ilter` with a zero-width space in the middle might not be detected.

Frequently Asked Questions

What is the difference between a zero-width space and a regular space?

A regular space (the one you make with your spacebar) has a visible width and is used to separate words. A zero-width space has no width and is completely invisible. It is primarily used for technical reasons, like telling a computer program where it's okay to break a long word into a new line, but it has many other creative uses.

Will this work on all websites and apps?

Not always. While most modern browsers and apps that support Unicode will recognize the character, some websites have stricter validation on their input fields (especially for usernames) and may strip it out or reject it. It is most likely to work on platforms with large user bases like TikTok, X (Twitter), and Instagram.

Can people see the zero-width space character?

No, the character itself is completely invisible to the human eye. Someone would only know it's there if they copied the text into a character counter or a text editor that can highlight special characters. That is what makes it so useful (and sneaky!).

How is this different from the Zero-Width Non-Joiner (ZWNJ)?

They serve different purposes. A Zero-Width Space (ZWSP) is used to indicate a potential line break in a long word. A Zero-Width Non-Joiner (ZWNJ), on the other hand, is used to prevent two characters from connecting or ligating. For example, in some languages, it can force two letters to be rendered separately instead of as a single combined character.

Is using a zero-width space safe?

Yes, it's completely safe. It's a standard Unicode character and doesn't contain any malicious code. However, it can be used to cause confusion (for example, by making two different usernames look identical), which is why some platforms may choose to block it.
