Paste text with extra spaces or tabs, pick Collapse spaces / Trim each line / Drop blank lines / Remove all spaces, then Copy the cleaned result - everything stays in your browser.
Collapse spaces trims each line and replaces runs of spaces or tabs with a single space while keeping line breaks. Use Trim each line when you only want edge spaces gone, Drop blank lines to remove empty rows, or Remove all spaces to strip spaces, tabs, and non-breaking spaces while preserving newlines.

Cleanup options
- Collapse spaces (default) trims each line and replaces runs of spaces or tabs with a single space while keeping line breaks.
- Trim each line removes leading and trailing spaces/tabs without changing the words in the middle.
- Drop blank lines removes empty or space-only lines so the kept lines stay in order.
- Remove all spaces deletes spaces, tabs, and non-breaking spaces (U+00A0) while preserving newlines.
What each option leaves untouched
Collapse spaces, Trim each line, and Drop blank lines only match plain spaces and tabs. None of them touch a non-breaking space - the invisible character often left behind when you copy text from a web page or a Word document - so a line built only from non-breaking spaces will not count as blank, and a run of non-breaking spaces will not shrink under Collapse.
Remove all spaces is the one option built to catch that case: its cleanup pass strips regular spaces, tabs, and non-breaking spaces together, and as a side effect it also turns any Windows-style line ending in the pasted text into a plain line break, so mixed-origin text ends up with one consistent line-ending style either way. Trim each line and Collapse spaces are not interchangeable either - Trim only strips the space at the start and end of each line and leaves any doubled-up spacing in the middle exactly as pasted, while Collapse is the option that reduces that middle spacing to a single space.
| Option | Leading/trailing spaces | Multiple spaces mid-line | Blank lines | Non-breaking space (U+00A0) |
|---|---|---|---|---|
| Collapse spaces | Trimmed | Reduced to one space | Kept | Kept |
| Trim each line | Trimmed | Kept as pasted | Kept | Kept |
| Drop blank lines | Kept | Kept as pasted | Removed | Kept (an NBSP-only line does not count as blank) |
| Remove all spaces | Removed | Removed | Kept (line breaks preserved, CRLF normalized to LF) | Removed |
A concrete case this covers: if a pasted line has two non-breaking spaces sitting between two words - common after copying from a spec sheet, a spreadsheet, or a PDF-exported table - that gap survives Collapse spaces, Trim each line, and Drop blank lines exactly as pasted, because none of those three match U+00A0. Only Remove all spaces closes it, since Remove all spaces is the only one of the four whose matching pattern includes the non-breaking space alongside the plain space and tab characters it always removes. If a page still looks like it has a stray gap after Collapse spaces, that non-breaking-space boundary is the first thing to check.
Common uses
Use it to tidy pasted notes, CSV-ish rows, or code comments before you paste them into another app. Prefer this when you want a quick text cleanup without installing an editor or sending text to a server. The tool opens with a short two-line sample already pasted and cleaned, so the output area shows a result before you type anything - a quick way to see how Collapse spaces, Trim each line, Drop blank lines, and Remove all spaces each change text without committing your own content first.
How it differs
Distinct from Remove Duplicate Lines (which keeps unique lines) and Case Converter (which changes letter case, not spacing).
Privacy
Copy puts the cleaned text on the clipboard; nothing you paste is saved between visits. The Copy button is built to work even where the modern clipboard API is missing - for example inside some embedded frames or an older browser - by falling back to selecting the output box and copying the current selection, so the cleaned text still reaches your clipboard either way.
Frequently Asked Questions
What does Whitespace Remover do?
Paste text with extra spaces or tabs and clean it in your browser - no upload and no account. You can collapse space runs, trim each line, drop blank lines, or remove all spaces.
Does my text leave this device?
No. Cleanup runs locally in the page. Copy puts the cleaned text on the clipboard; nothing you paste is saved between visits.
When should I use this instead of Remove Duplicate Lines or Case Converter?
Prefer this for a quick text cleanup of spacing. Distinct from Remove Duplicate Lines (which keeps unique lines) and Case Converter (which changes letter case, not spacing).
Does it crop images or remove photo backgrounds?
No. It does not remove image whitespace, crop photos, or run AI models - paste text only.
Does Copy still work if my browser blocks clipboard access?
Yes. Copy first tries the browser's clipboard API; if that is unavailable it falls back to selecting the cleaned text and running the browser's built-in copy command, so the button still works in a locked-down browser or an embedded view.
Is there already an example loaded when I open the page?
Yes. The input starts with a short two-line sample that already has extra spaces, a blank line, and a tab in it, so the cleaned result is visible before you paste your own text.
