Optionally collapse multiple spaces, remove empty lines, and normalize line endings (e.g. to Unix).

Click Trim

The tool trims leading and trailing whitespace from each line and applies your options in the browser.

Copy the output

Copy the cleaned text to your clipboard for use in code, configs, or other tools.

Why Trim Whitespace?

Extra spaces and inconsistent line endings cause parse errors, diff noise, and messy data. Trimming whitespace normalizes text so it behaves consistently in code and configs.

Useful when you need to:

Clean pasted text

Remove stray spaces and tabs from copy-pasted content before using it in code or docs.

Normalize line endings

Convert Windows (CRLF) or mixed line endings to a single style (e.g. LF) for consistent behavior.

Collapse multiple spaces

Turn runs of spaces into a single space to tidy fixed-width or inconsistently spaced text.

Remove empty lines

Strip blank lines to compact lists, logs, or configs without manual editing.

Private and Secure

Your text is never uploaded to a server. This tool runs entirely in your browser using client-side processing.

Data stays on your device

Your data never leaves your browser. No uploads, no cloud storage, no logs.

Nothing stored or sent

No text is stored or transmitted. Trimming happens only in memory.

Fast and private

Trimming is instant and runs locally at full browser speed.
