What is this text cleaner?

This is a free, browser-based text cleaner that strips extra spaces, blank lines, tabs and invisible Unicode characters from any text — with toggleable options and a live preview, and with zero data leaving your device, because every operation runs in JavaScript on your own machine.

How do I remove extra spaces, blank lines and hidden characters from text online without uploading it?

Paste your text and the cleaned result appears instantly. Toggle which cleaners to apply — collapse spaces, trim lines, limit blank lines, strip zero-width characters and more. Nothing is uploaded; it all runs in your browser.

Key features

Eight cleaners, one panel
Trim line ends, collapse runs of spaces, limit consecutive blank lines, convert tabs to spaces, normalise line endings, strip zero-width and invisible Unicode, remove non-breaking spaces and trim the whole text.
Toggle what you need
Each cleaner is a switch you can turn on or off, so the tool fits your case instead of forcing a fixed pipeline.
Live with savings
The output updates as you type and reports how many characters and bytes were removed compared to the original.
Unicode-aware
Removes invisible characters like zero-width spaces (U+200B), zero-width joiners and the byte-order mark while preserving your real content.

How to use it

Paste or type your text on the left. Turn the cleaners you want on or off in the options bar — the cleaned text updates instantly on the right with the bytes saved. Copy or download the result; nothing is sent to a server.

Frequently asked questions

Is my text uploaded to a server?

No. The cleaner runs entirely in your browser, so even confidential drafts and copy-paste from production stay private.

What are zero-width and invisible characters?

Hidden Unicode characters like U+200B (zero-width space), U+200C/D (joiners) and U+FEFF (byte-order mark) that often sneak in from copy-pasted web text and can break diffs, IDs or URL slugs.

Will it touch text inside code blocks or quotes?

It applies the cleaners you enabled to all text equally; if you only want whitespace tidying without touching tabs, switch the tab cleaner off.

Built by the Toolbox team using ECMAScript string and Unicode regexes (including \u200B–\u200D and \uFEFF) and tested against common real-world copy-paste sources, so the cleaned output matches what editors and validators expect.
