A text space remover with nothing to upload

This tool removes every character Unicode classifies as whitespace from a block of text and returns one unbroken string. That is a wider definition than most people expect from a space remover: it covers the space bar character, tabs, line breaks, non-breaking spaces, and the narrower Unicode spaces (thin, hair, ideographic) that render identically to a normal space but sit at a different codepoint.

It is a client-side transformer, not a server tool. The whole operation runs in JavaScript in your browser the instant you press the button. Nothing is sent anywhere, which is also why there is no run limit and no length cap: the constraint on a local operation is your own device, not an allowance we track.

The tool matches the Unicode whitespace property as a set, not a single character, which is the entire reason it succeeds where find-and-replace fails.

The space bar character

U+0020, the one ordinary find-and-replace searches for.

Non-breaking space

U+00A0, extremely common in text copied out of a web page.

Tabs, carriage returns and newlines

Every line-break and tab character in the input.

The narrower Unicode spaces

Thin space, hair space and the rest of the U+2000 to U+200A block.

Ideographic space

U+3000, used in Chinese, Japanese and Korean typesetting.

No configuration, because there is nothing to configure: this tool has one job and does it in one pass.

Step 1

Paste the text into the input field. Length is not a constraint the tool imposes.

Step 2

Run the removal. The pass executes locally and completes essentially instantly for anything short of an extremely large document.

Step 3

Copy the output: one continuous string with every whitespace character removed.

Zero-width characters, most notably the zero-width space, are not classified as whitespace under Unicode's own rules; they belong to a formatting category instead. That means this tool leaves them in place by design, not by oversight.

If invisible zero-width characters, rather than visible-looking whitespace, are the actual problem (breaking a search, a slug or a string comparison) the dedicated zero-width space remover on this site is the correct tool. Running both in sequence covers whitespace and zero-width characters as the two separate classes they actually are.

A word processor's find-and-replace searches for one exact codepoint, almost always the regular space. Every other whitespace character is a different codepoint that renders identically on screen and simply never matches that search, no matter how many times it runs.

This tool does not search for a character; it matches an entire Unicode category in one pass, which is the structural reason nothing is left behind afterward.

This tool is for producing one continuous string with no whitespace at all, the shape a slug, a key, a filename or a whitespace-rejecting field actually needs. Run it on a paragraph of prose and every word joins into an unreadable block, which is correct behaviour for this tool and the wrong tool for that job.

Collapsing repeated spaces down to a single space while keeping normal word spacing is the whitespace minifier's job, a different operation with a different output shape. Picking between the two is the single most common source of confusion, and the distinction is worth making explicit before you run either.

The same operation, applied at a few distinct points in a workflow.

Engineers

Cleaning a value copied from documentation before it goes into code, where a stray non-breaking space becomes a silent syntax error.

Data teams

Fixing a spreadsheet column carrying invisible whitespace that breaks a lookup or a join.

Anyone generating identifiers

Slugs, filenames, database keys and tokens that reject whitespace outright.

Localization work

Text sourced from Chinese, Japanese or Korean content, carrying an ideographic space most Western tooling doesn't expect.
