Blank lines in text cause problems in many contexts: CSV files with blank rows break imports. Code with excessive blank lines fails linters. Email templates with blank lines render incorrectly in some clients. Data exported from spreadsheets often has trailing blank rows. This tool handles all these cases cleanly.

Copy-pasting from PDFs, emails, websites, or Word documents often introduces blank lines because different applications use different newline conventions. PDFs use carriage returns that paste as blank lines. HTML paragraph tags become double newlines. Outlook email adds extra line breaks. Some copy operations capture formatting as blank lines. This tool removes all of them instantly without affecting the actual content.
If your text uses blank lines as paragraph separators (standard for web/digital text), removing ALL blank lines will merge paragraphs together. Use the "Collapse multiple blanks into one" option instead to preserve paragraph structure while removing extra blank lines. This is ideal for cleaning up text that has 2-3 blank lines between paragraphs (common in PDF-to-text conversions) while keeping single blank line paragraph breaks intact.
Yes — this tool works on any plain text including code files. For code, the "Collapse multiple blanks into one" option is usually better than removing all blank lines, as single blank lines in code are intentional for readability (separating functions or logic blocks). Many code style guides (PEP8 for Python, ESLint for JavaScript) specifically allow up to 2 consecutive blank lines and flag more as a linting error.
Windows text files use CRLF (carriage return + line feed, \r\n) while Unix/Mac use LF (\n) only. This tool normalises line endings during processing, so it correctly identifies and removes blank lines regardless of which line ending format your text uses. The output uses the line ending style of your browser/OS. If you need specific line ending format control, use a dedicated text editor with encoding options.
For single texts, this browser tool is fastest. For bulk files or automation: Linux/Mac terminal: grep -v "^$" file.txt > output.txt. Python: result = "\n".join(line for line in text.split("\n") if line.strip()). PowerShell: Get-Content file.txt | Where-Object {$_ -ne ""} | Set-Content output.txt. Sed: sed "/^$/d" file.txt. For directories of files, wrap any of these in a shell loop or Python os.walk() call.
