💡 How it works:

Paste or type your text in the textarea above
The tool automatically detects and removes all blank lines
Preserves the content of non-empty lines
Handles multiple consecutive blank lines
Trims whitespace-only lines (spaces, tabs, etc.)
Statistics show lines removed and lines remaining

📝 Examples:

Input (With Blank Lines):

Line 1 Line 2 Line 3 Line 4

Output (Cleaned):

Line 1 Line 2 Line 3 Line 4

Statistics:

Original Lines: 7
Cleaned Lines: 4
Removed Lines: 3

Input (With Whitespace-Only Lines):

First line Second line Third line

Output (Cleaned):

First line Second line Third line

📚 Use Cases:

Format lists and remove gaps between items
Organize document content and remove spacing
Prepare text for data processing or analysis
Reduce file size by removing empty lines
Standardize formatting across multiple documents
Clean logs and console output

ℹ️ Note: This tool removes completely blank lines and lines containing only whitespace (spaces, tabs). Content lines are preserved exactly as-is.

What the filter treats as blank

The text is cut on either line ending, each line is tested after trimming, and the survivors are rejoined:

lines  = text.split(/\r?\n/)        both LF and CRLF understood
keep   = lines where line.trim() !== ""
output = keep.join("\n")

JavaScript's trim() counts more than the space bar: tabs, form feeds, a non-breaking space pasted from Word and even a stray byte-order mark all trim away, so those lines are dropped as blank. A zero-width space (U+200B) is not whitespace, so a line holding only that one invisible character survives - which is why a stubborn "empty" line sometimes refuses to go.

Points to check before you copy

Line endings are normalised. Windows CRLF input comes back with plain LF endings. That is what most editors and Git want, but a .bat file or an old mainframe format may not.
Content lines are never touched. Leading indentation and trailing spaces on a non-blank line survive exactly, so pasted code keeps its structure.
Every blank line goes, not just the extras. There is no "collapse to one" mode, so paragraphs of prose will run together into a single block.
Original Lines counts what you pasted, including the empty line a trailing newline creates at the end of the file.

Markdown and YAML both use blank lines as syntax - a heading or a list needs the gap above it. Strip them and the document changes meaning, even though the text is intact.

Frequently asked questions

How do I remove blank lines in Word or Notepad++?

In Word, use Find and Replace with ^p^p replaced by ^p and run it until no matches remain. Notepad++ has it built in at Edit, Line Operations, Remove Empty Lines. Pasting here is faster when you only need it once.

Is it safe to run source code through this?

For Python, JavaScript and most languages, yes - blank lines are ignored by the parser, though the result is much harder to read. Never do it to Markdown, YAML or a Git commit message, where a blank line separates blocks.

Why did it remove more lines than I could see?

Lines holding only spaces, tabs or a non-breaking space look empty on screen and are counted as blank. Compare Original Lines with Removed Lines to see how many were invisible rather than truly empty.
