Options Explained
- Trim Mode: Select Both Leading & Trailing to strip whitespace from both ends of every line. Choose Leading Spaces Only (Left) or Trailing Spaces Only (Right) to clean just one side.
- Empty Lines: Choose Keep Empty Lines to preserve all blank lines in their original positions. Select Merge Empty Lines to collapse consecutive blank lines, or Remove Empty Lines to delete them.
- Spaces: Removes standard spaces from the start, end, or both sides of each line. Uncheck this box to keep regular space indentation while stripping edge tabs or Unicode spaces.
- Tabs: Strips horizontal tab characters from the selected edges of each text line. Uncheck this option to preserve tab indentation or keep empty edge columns in tab-separated lists.
- Unicode Spaces: Removes non-breaking spaces, full-width CJK spaces, narrow spaces, and byte order marks from line edges. Uncheck this box if your text needs intentional non-breaking or full-width spaces at line ends.

Frequently Asked Questions
How do I remove only trailing spaces while keeping leading indentation on each line?
Select Trailing Spaces Only (Right) in the Trim Mode dropdown menu above. The tool strips spaces and tabs from the right end while leaving left indentation intact.
Does this tool remove repeated spaces or tabs between words inside a line?
No, this remover only strips whitespace from the start and end of each line. All internal spaces and tabs between words remain untouched unless you use our Whitespace Remover.
How can I trim leading and trailing spaces without removing tab characters in TSV data?
Uncheck the Tabs checkbox while keeping the Spaces option enabled in the settings above. This strips unwanted edge spaces from each row while preserving leading or trailing tab delimiters.
How do Keep Empty Lines, Merge Empty Lines, and Remove Empty Lines handle blank lines?
Lines containing only spaces become blank after trimming, and Keep Empty Lines preserves their exact row positions. Merge Empty Lines collapses consecutive blank lines into one, while Remove Empty Lines deletes them completely.
Which international whitespace characters does the Unicode Spaces option remove from line edges?
It removes non-breaking spaces, full-width CJK spaces, thin or hair spaces, and byte order marks. All accented letters, non-Latin scripts, and emojis on your lines remain completely untouched during trimming.
Are my text lines stored or sent to a server when I trim spaces?
No, all line trimming and empty-line filtering run locally inside your browser memory. Your text never leaves your device because this tool operates with zero server data storage.
