How to use the space cleaner
Paste your text and switch on the fixes you need. "Collapse multiple spaces" turns any run of spaces into a single space. "Trim each line" removes leading and trailing spaces from every line. "Remove empty lines" deletes blank lines entirely. "Strip all line breaks" flattens the whole text into one continuous line. "Convert tabs to spaces" replaces tab characters, which often hide behind what looks like ordinary spacing. The result and a running character count update as you type, and one click copies it.
Why text arrives messy
Spacing problems creep in whenever text moves between programs. Copying from a PDF frequently inserts stray spaces and hard line breaks in the middle of sentences. Pasting from email or chat brings along inconsistent indentation. Exports from spreadsheets and databases pad fields with trailing spaces you cannot see. Old documents mix tabs and spaces for alignment that falls apart the moment the font changes. None of this is visible at a glance, but it breaks layouts, inflates character counts, and causes "identical" values to be treated as different. This cleaner targets each of those problems with a specific toggle so you fix only what is actually wrong.
What each fix is best for
Use "collapse spaces" and "trim lines" together as your default cleanup — they resolve the vast majority of everyday spacing mess without changing the structure of your text. Reach for "strip all line breaks" when you have copied a paragraph from a PDF that broke every line at the page margin and you want it to reflow as a single block. Turn on "remove empty lines" to tighten a list or to undo the double-spacing that some editors add between paragraphs. "Convert tabs to spaces" is the fix for text that looks fine until you paste it somewhere that renders tabs differently, at which point the alignment collapses.
Tips and order of operations
When you are cleaning text to compare or deduplicate it, run it through here first: trimming lines and collapsing spaces means the duplicate remover and diff checker compare real content instead of invisible whitespace. If a character limit tool says your text is longer than it looks, extra spaces are usually the culprit — collapse them and watch the count drop. Be a little careful with "strip all line breaks" on structured text like addresses or code, where line breaks are meaningful; it is designed for prose that should flow. The tool applies your fixes together in a sensible order, so you can combine several at once and see the combined result immediately, all computed in your browser with nothing uploaded.
