Empty Line Remover
Remove blank and empty lines from your text instantly. Clean up extra spacing between paragraphs and get compact, clean text in one click.
Remove Blank Lines or Collapse Them to One
When you copy text from a document, email, or web page, the result often contains far more vertical space than you need. Some documents use double or triple blank lines between every paragraph. Others insert blank lines after every heading, list item, or table row. This extra vertical spacing creates a cluttered, hard-to-read result when pasted into a plain text editor, content management system, or code file. The empty line remover on this page gives you precise control over which blank lines to strip and which to keep, so you can clean up your text without losing meaningful structure.
What Counts as an Empty Line
An empty line is any line in a block of text that contains no visible characters. At the most basic level, this means a line that is completely blank, with nothing between the two newline characters that bound it. However, a line can also appear visually empty while still containing invisible characters such as spaces or tab characters. Depending on your use case, you may want to treat these whitespace-only lines the same as fully empty ones, or you may want to keep them because they carry intentional indentation. The removal options on this tool let you choose exactly how to handle both cases. To also strip extra spaces and trailing whitespace from individual lines, use the remove white spaces tool alongside this one.
Remove Blank Lines
The simplest operation is to remove all blank lines entirely, leaving only lines that contain actual content. The result is a compact block of text where every line carries something meaningful. This is the right choice when you are preparing text for a system that does not need paragraph separation, such as a spreadsheet cell, a database field, a single-line input, or a log file entry. If you need to remove line breaks within individual lines as well rather than just the blank lines between them, the remove line breaks tool handles that operation with options to replace breaks with spaces or commas.
Whitespace-Only Lines Count Too
A common source of confusion when cleaning pasted text is that some lines look empty on screen but are not truly empty in the underlying data. A line containing a single space, four spaces representing an indent, or a tab character will appear blank to the naked eye but will not be caught by a simple check for zero-length lines. The "Remove lines containing only whitespace" option uses a pattern that matches any line where every character is a whitespace character, including spaces, tabs, and carriage returns. This catches all visually blank lines regardless of whether they contain invisible characters. For deeper cleanup that targets individual character types, the remove white spaces tool lets you strip leading spaces, trailing spaces, or double spaces from content lines.

Removal Options
The tool offers four distinct removal modes. Remove all empty lines strips every line that has no content, joining your paragraphs into a tight block with no vertical breathing room. Collapse multiple blank lines to single finds any sequence of two or more consecutive blank lines and reduces it to exactly one blank line, preserving paragraph separation while eliminating excess spacing. Remove lines containing only whitespace targets lines that appear empty but contain invisible space or tab characters. Remove trailing empty lines only trims blank lines from the end of the document without touching any spacing in the middle, which is useful when your content has a clean body but an untidy tail of blank lines at the bottom.
Cleaning Up Code, Pasted Text, and Documents
Excess blank lines appear in nearly every context where text is copied, exported, or generated automatically. Whether you are working with source code, a pasted article, a CSV export, or an email thread, the empty line remover handles the cleanup in one click. The three most common workflows are cleaning code files, formatting text documents, and preparing data for further processing.
Cleaning Code Files
Developers often copy code snippets from documentation, Stack Overflow answers, or AI-generated output and find that the pasted code contains far more blank lines than the original project style guide permits. Some style guides allow at most one blank line between functions and zero blank lines inside function bodies. Paste the code into this tool, choose the collapse option to reduce multiple consecutive blank lines to one, and get a result that matches the expected formatting. For generating or converting code between languages, the AI code converter handles structural transformations before you clean up the spacing.
Formatting Text Documents
When you copy text from a PDF, a Word document, or a web article and paste it into a plain text field or a content editor, the result frequently includes double or triple blank lines where the original had single paragraph breaks. This happens because each paragraph in the original may have had extra spacing applied through the document's styling rather than through actual blank lines in the text. The converter normalizes this by collapsing multiple blank lines to one, giving you clean paragraph separation without the excessive gaps. Once the blank lines are cleaned up, you can use the auto break text into paragraphs tool to restructure long blocks of text that lost their paragraph separation entirely.
Preparing Data for Processing
Data pipelines that ingest line-delimited text, such as CSV parsers, log analyzers, or natural language processing scripts, often break when they encounter unexpected blank lines in the input. An empty line in the middle of a CSV file can shift all subsequent rows by one position, causing column misalignment. An empty line in a log file may be misinterpreted as a record separator. Stripping all blank lines before passing the data to the next step in the pipeline prevents these issues. For more advanced text transformations after cleaning, the AI text analyzer can help you understand the structure and content of your cleaned text.
Compact Output Without Losing Paragraph Structure
The most common challenge when removing blank lines is avoiding the loss of meaningful paragraph structure. If you strip every blank line, paragraphs run together into a single wall of text with no visual separation. The collapse option solves this by reducing sequences of two or more blank lines to exactly one blank line, which most text rendering environments treat as a paragraph break. This gives you compact output while preserving the visual grouping of your content.
Removing All Blank Lines
When you choose the remove all option, every line matching the pattern for an empty line is deleted and the surrounding lines are joined together. The result is a dense block of text with no vertical spacing anywhere in the document. This is appropriate for content that will be parsed by a machine, inserted into a single input field, or reformatted by a downstream tool that manages its own paragraph structure. If you need to reintroduce paragraph breaks after removing them all, the paragraph formatter can split a block of text into paragraphs automatically.
Collapsing Multiple Blanks to One
The collapse option is the most balanced choice for documents where you want to keep paragraph separation but remove excessive gaps. It finds any run of two or more consecutive blank lines and replaces the entire run with a single blank line. A document that had triple-spaced sections between every heading will emerge with the same structural separation but without the wasteful extra space. This is the recommended option for documents being imported into a blog editor, a content management system, or a Markdown-based publishing workflow. For further cleaning of the content after collapsing blank lines, the sort lines alphabetically tool can reorganize line-based content into alphabetical order.
Removing Whitespace-Only Lines
The whitespace-only option targets a specific class of invisible line that neither the basic remove-all option nor a simple check for zero-length lines catches reliably. Lines containing one or more spaces or tabs appear empty on screen but are stored with actual characters. This is common in text pasted from rich text editors, formatted emails, or source code where indentation was partially preserved. Removing these lines produces a cleaner result for text processing tasks, log analysis, and any context where trailing or embedded whitespace causes issues. To clean up whitespace within individual lines rather than between them, use the remove white spaces tool.
FAQ
Does it remove lines with spaces?
The basic "Remove all empty lines" option removes lines that are completely empty, meaning lines with a length of zero. Lines that contain only spaces are not caught by this option. To remove lines that appear blank but contain spaces or tabs, use the "Remove lines containing only whitespace" option, which matches any line where every character is a whitespace character.
Can I keep single blank lines?
Yes. The "Collapse multiple blank lines to single" option reduces any sequence of two or more consecutive blank lines down to exactly one blank line. Single blank lines that already appear alone between paragraphs are left exactly as they are. This is the right choice when you want to preserve paragraph separation while removing excessive gaps caused by double or triple spacing.
Does it work with code files?
Yes. Paste your code into the textarea and choose the collapse option to reduce multiple consecutive blank lines to one. This is useful for bringing pasted code snippets into alignment with style guides that limit blank lines within functions or between class definitions. The tool only removes blank lines and does not alter any code logic, variable names, or formatting within individual lines.
What about tab-only lines?
Lines containing only tab characters are treated as whitespace-only lines and are caught by the "Remove lines containing only whitespace" option. The standard remove-all option does not catch them because tab-only lines have a non-zero length. If your text came from a code editor or a document with indented blank lines, the whitespace-only option is the one to use.
Can I remove only trailing blanks?
Yes. The "Remove trailing empty lines only" option scans from the end of your text backward and removes any blank lines it finds until it reaches the first line with actual content. Everything above that point is returned unchanged. This is useful when your document body is correctly formatted but has a run of blank lines at the end that you want to trim without touching anything else.
What is remove newlines?
Remove newlines refers to the process of stripping line break characters from text. In the context of blank line removal, removing newlines means deleting the newline characters that create empty lines between paragraphs. This is different from removing all newlines in the text, which would join every line into a single continuous block. For removing all newlines from text, the remove line breaks tool provides that option alongside others.
What is remove new lines?
Remove new lines is another way of describing the same operation as removing line breaks or newlines. When someone searches for "remove new lines," they are typically looking for a tool that strips the invisible newline characters that force text onto separate lines. This tool focuses specifically on blank and empty new lines rather than all new lines, preserving the lines that contain actual content.
What is blank line remover?
A blank line remover is a text cleaning tool that finds and deletes empty lines from a block of text. It can remove all blank lines or selectively remove them based on rules such as collapsing multiple consecutive blanks into one or targeting only lines that contain invisible whitespace characters. This tool is the blank line remover on this page, with four removal options to match different use cases.
What is line remover?
A line remover is a general term for any tool that deletes specific lines from a block of text. In the context of text formatting, a line remover typically targets blank, empty, or unwanted lines and removes them to produce cleaner output. This empty line remover is a type of line remover focused on blank and whitespace-only lines. For removing specific text patterns within lines rather than entire blank lines, the replace text online tool lets you find and remove specific words or phrases from your content.
