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.
Private and instant
Everything runs locally in your browser using standard web APIs — nothing is uploaded, logged, or stored on any server — so the tool works offline, responds instantly, and keeps whatever you paste in on your own device. That makes it safe to use even for confidential, client, or internal data you would never send to an unknown website.
