Whitespace Normalizer (Full-width to Half-width, Repeated Space Cleanup)
Clean up full-width spaces, NBSP, TAB, and repeated spaces before you paste or reuse text.
Switch between presets for general text, single-line forms, code-safe spacing, and French no-break space protection.
Your input is processed in this browser only and is never sent to a server.
Normalize whitespace without touching the text itself
This tool targets whitespace only. It helps with Japanese full-width spaces, multilingual no-break spaces, and repeated ASCII spaces while giving you a safer path for code, tables, and logs.
How to use
- Paste your text.
- Choose a preset or adjust full-width spaces, repeated spaces, and line-break handling.
- Run normalization and review the summary and diff.
- Copy, download, or send the result back for another pass.

FAQ
Is my text uploaded anywhere?
No. Everything runs inside your browser.
Can I convert only full-width spaces?
Yes. Leave the full-width space option on and turn the other cleanup rules off.
I only want to remove repeated spaces.
Turn on repeated-space collapsing. If your content includes code or aligned tables, use the code-safe preset.
Will this break code or aligned tables?
The general preset may compress meaningful spacing. For code, tables, or logs, use the code-safe preset.
Does it handle French no-break spaces?
Yes. The French spacing safe preset keeps protected no-break spaces while cleaning the rest.
Can I remove all line breaks and turn the text into one line?
Yes. Set line-break handling to Flatten to single line and line breaks will be replaced with a single regular space.
Can I share only the settings?
Yes. The shared URL contains settings only, never the input text.
Notes
- Whitespace may be meaningful in passwords, signatures, tokens, Base64, code, and Markdown tables.
- If no-break spaces matter in your language or typography rules, use a dedicated preset instead of the general one.
- The shared URL does not include the text, but anyone with the link can still see the chosen settings.
