About Whitespace Remover — Trim Spaces & Blank Lines
Pasted text rarely comes in clean. Copy from a PDF, an email, a chat, or a log file and you inherit ragged indentation, double spaces, stray tabs, invisible non-breaking spaces, and blank lines scattered throughout. This whitespace trimmer fixes all of that in one place, so you can paste messy content and get tidy, predictable text back.
Each action does one job: trim the ends of every line, collapse runs of spaces and tabs down to a single space, remove blank lines, strip trailing whitespace, or strip every whitespace character entirely. Pick the transform you need and the result updates live as you type.
Everything runs locally in your browser — nothing you paste is ever uploaded. That makes it safe for cleaning up logs, config snippets, or anything else you would rather not send to a server.

Frequently asked questions
What is the difference between trimming lines and stripping trailing whitespace?
Trim lines removes whitespace from both ends of each line, including leading indentation. Strip trailing only removes whitespace at the end of each line and drops trailing blank lines, leaving your leading indentation intact.
Does it remove invisible characters like non-breaking spaces?
Yes. The collapse, trim, and remove-all actions recognise non-breaking spaces, zero-width spaces, and byte-order marks in addition to ordinary spaces and tabs, so hidden characters that sneak in from PDFs or web pages get cleaned up too.
Will it change my line breaks?
Trim, collapse, and strip operate per line and keep your newlines. Remove blank lines deletes empty and whitespace-only lines, and Remove all whitespace strips newlines as well — use it only when you want a single unbroken string.
Is my text sent anywhere?
No. All cleaning happens locally in your browser. Your input never leaves your device, so it is safe to use on logs, secrets, or private content.
