Trailing Whitespace Remover
Remove trailing spaces and tabs from every pasted line.
Strip trailing whitespace
Trailing spaces and tabs are invisible but real — they bloat diffs, trip up linters, and cause subtle bugs in whitespace-sensitive formats. This tool removes trailing whitespace from every line of pasted text, leaving the content untouched.
Cleaning it out keeps files tidy and diffs meaningful, which many teams enforce automatically. Paste your text or code, get a version with clean line endings, and copy it back — a small fix that keeps a codebase neat.
Cleaner diffs, locally
Stripping trailing spaces and tabs shrinks diffs and quiets linters without touching your content. It runs in your browser and never uploads anything.
Frequently asked questions
What does it remove?
Spaces and tabs at the end of every line. Line breaks and indentation at the start of lines stay.
Why remove trailing whitespace?
It creates noisy diffs and can trip linters, and some formats, like Markdown, treat trailing spaces as line breaks.
Does it change blank lines?
Blank lines are kept, but any spaces on them are removed.
