Technical precision
Clean character blocks, nothing extra. Each tool copies the exact code point you asked for, in the format you chose, with its real width and byte size measured live in your browser. No stray spaces, no silent substitutions.

About Our Project
We build precise, zero-byte Unicode whitespace utilities that copy clean character blocks to your clipboard in one click, so developers, designers and social layout curators can fix text that other tools leave broken.
Our mission
A reliable home for every invisible character
Invisible and fixed-width characters are everywhere in modern text, and almost nowhere documented well. A designer needs a full-width space to align a Japanese name field. A developer needs a zero-width space so a long URL wraps on a phone. A streamer wants a blank display name that a game actually accepts. Each of these is a different Unicode character with its own rules, and the usual advice is a forum post from eight years ago with a space you cannot even see to copy.
We started this project to replace that guesswork with tools you can trust. Every page here does one job well: it hands you the exact character you need, in the exact format you need, measured and verified in your own browser before you paste it anywhere. No sign-up, no upload, no tracking. The text you type never leaves your device, because every utility runs entirely in client-side JavaScript. Close the tab and nothing remains on a server, because nothing was ever sent to one.
The platform is deliberately lightweight. A page loads in a fraction of a second, works offline once it has loaded, and runs on a five-year-old phone as happily as on a workstation. We treat that restraint as a feature, not a limitation. People reach for a blank-text tool in the middle of another task, often on mobile, often in a hurry, and the last thing they need is a heavy app that asks them to register before it will copy a single character.
Accuracy matters more to us than reach. Plenty of sites claim a space character will bypass any filter or make any field blank. Most of those claims are false, and we say so on the pages where it matters. A space separator is removed by a trim, so it cannot make an empty username stick; a letter-class blank like the Hangul Filler can. We would rather tell you which character actually works than sell you a shortcut that fails the moment a server normalises your input. That honesty runs through every comparison table and every live validator on the site.
Who we build for shapes every decision. Web developers get code tokens in HTML, CSS, JavaScript and URL-encoded form, plus validators that catch the invisible characters behind a cryptic syntax error. Designers and typographers get fixed-width spaces measured to the em, so a layout holds its margins across viewports. Social media and gaming layout curators get one-click blanks for bios, comments, chat and profile names, with clear guidance on what each platform allows. QA engineers get a master index they can turn into a test fixture in two clicks. The same character set serves all of them; what changes is the context and the guidance wrapped around it.
Every tool ships with its “How to Use” steps built into the page, directly beneath the utility, not buried in a separate manual. We think a tool should teach you as you use it. If a character behaves differently in Chrome than in a text editor, the page measures both and shows you the result rather than asking you to take our word for it. That combination, a working tool and an honest explanation side by side, is the standard we hold every page to.
The work is ongoing. Unicode keeps evolving, platforms keep changing their validation rules, and browsers keep rendering edge cases in their own ways. We keep the tools current, correct the moment we find an inaccuracy, and expand the library as new use cases appear. The goal is simple and unchanging: when you need an invisible character, this should be the one place that gives you the right one and tells you the truth about it.
What we build around
Three priorities decide how every tool on the site is made.
User-centric design
One click copies to your clipboard, with a clear confirmation. Every page carries its own “How to Use” steps directly beneath the tool, so the guidance is where you need it, exactly when you need it.
Platform compatibility
We test how characters behave across browsers, operating systems, social apps and game clients, and we document where they work and where they fail. The right character for Instagram is not always the right one for a code file, and the pages say which is which.
Why we built it
Three problems, one toolkit
This platform exists to solve three stubborn problems that share a single root cause: the gap between how text looks and how software reads it.
- Broken responsive layouts. A price that splits from its currency on a narrow screen, a long word that overflows its column, a heading with one orphan word on the last line. The right fixed-width or no-break character fixes each one without a media query, and our wrap demos show the result at any width.
- Profile and name restrictions. Fields that reject a normal space, block the Enter key, or demand text where you want a blank. The tools give you the character that each platform actually accepts, with honest notes on what gets trimmed and what sticks.
- Rigid string testing. Invisible characters that corrupt data, break exact matches, or trigger a syntax error no one can see. Our detectors, validators and the master index turn those bugs into something you can find, reproduce and strip in a line of code.
Each page began as an answer to one of these, written for the person hitting the problem at that moment. Taken together, they add up to the reference we wished existed when we started: precise, private, fast, and honest about what these quiet little characters can and cannot do.
