Text Whitespace Remover allows you to paste any text and pick the operations you want: convert tabs to spaces (or vice versa) at a given tab width, change line endings between Unix LF, Windows CRLF and old-Mac CR, or strip trailing whitespace from every line. This online whitespace cleaner also lets you collapse runs of spaces into a single space, ensuring your code or prose is perfectly formatted.

Advanced Text Cleaning Features

Useful when prepping a code snippet for a blog post (no trailing whitespace, consistent indentation), normalising a file pasted from Windows for use on a Linux server, or fixing the inevitable mixed-tab-and-space indentation in a Python file. This space remover tool can be configured for any reasonable tab width (1 to 16); two and four are the most common for developer tasks.

Tabs ↔ spaces with configurable width
Line ending conversion (LF / CRLF / CR) for cross-platform compatibility
Strip trailing whitespace per line to keep files clean
Collapse multiple spaces into one with our whitespace normalizer
Combine multiple formatting operations in one pass

Frequently Asked Questions

What tab width should I use for Python?

PEP 8 recommends 4 spaces. Most Python projects (and Black, the formatter) enforce 4. Use 2 for JavaScript / Ruby projects that follow that convention.

What's the difference between LF, CRLF and CR line endings?

LF (\n) is Unix and modern macOS. CRLF (\r\n) is Windows. CR (\r) was classic Mac OS up to version 9 - rarely seen today but sometimes shows up in legacy files.

Will it break my text by collapsing spaces inside string literals?

Yes - collapse-runs-of-spaces is a blunt tool that affects everything, including string contents. Use it on prose, not code, unless you're sure no quoted whitespace matters.

Does it remove the UTF-8 byte-order-mark (BOM)?

If your input starts with a BOM (U+FEFF), the output won't include one. The tool always emits BOM-less UTF-8.
