Collapse extra spaces, trim stray whitespace and delete blank lines in one pass. Choose exactly which cleanup rules to apply and watch the character count drop live.
Turn runs of multiple spaces or tabs into a single space, anywhere in the text.
Strip leading and trailing whitespace from each line, plus optionally the whole document.
Remove lines that are empty or contain only whitespace, with one click.
Extra whitespace creeps into text more often than most people realize. Copying from a PDF or web page frequently brings along double spaces between sentences, stray tabs, or invisible trailing spaces at the end of lines. Text pasted from old documents sometimes still follows the double-space-after-period convention from typewriter days, which reads as inconsistent in modern digital typography. Collaborative editing adds its own mess: merged edits, accidental extra Enter presses, and copy-paste from spreadsheets can leave behind blank lines and irregular gaps that are invisible until the text is rendered somewhere that treats whitespace literally, such as a code block, a CSV field, or a strict content management system. None of these issues are visible at a glance in most editors, since a browser or word processor usually collapses adjacent spaces for display even though the extra characters are still there in the underlying text. That mismatch between what you see and what is actually stored is exactly why a dedicated pass matters before pasting text into a form, a database, source code, or anywhere the raw characters are preserved and compared exactly as typed.
Avoid unexpected whitespace differences when text is compared, diffed or stored exactly as typed.
One space between words and one blank line between sections reads as more polished and intentional.
Removing redundant characters shrinks file size and avoids hidden trailing-whitespace warnings.
Only whitespace. Depending on which options you enable, it can collapse repeated spaces into one, trim whitespace from the start and end of each line, delete fully blank lines, and trim whitespace from the very start and end of the whole text. Visible words and punctuation are never altered.
Only if you enable the Remove blank lines option, which deletes every line that is empty or contains only whitespace. Leave it unchecked to keep your paragraph spacing exactly as it is.
Collapsing multiple spaces to one applies everywhere in the text, including leading indentation, so it is best paired with the trim-line option if you are cleaning prose rather than indented code.
It is the difference between the length of your original text and the length of the cleaned result, updated live as you type or toggle options.
Yes. Cleanup happens entirely in your browser with no account or upload required.
