About Empty Line Remover
This empty line remover clears blank and whitespace-only lines from text for compact output. It supports three modes: remove only empty lines, remove whitespace-only lines, and remove empty lines while also trimming each line's leading and trailing whitespace. The tool splits on line boundaries and uses regex matching, correctly handling both Windows (CRLF) and Unix (LF) newlines - it detects which newline style your input uses and keeps that style in the output, so it never splits one line in two or merges two lines. Upon completion it reports the removed line count so you can confirm the effect. One nuance worth remembering: blank lines frequently act as paragraph separators in code and documents, so deleting every one can jam long content together; decide whether keeping a single blank line matters for readability. Choosing the trim option changes how whitespace-driven diffs look, so back up your original text first. Everything runs locally with no files uploaded, making it suitable for code, config files, and logs that need compact output before pasting into a spreadsheet or editor.

Use Cases
- Code compaction — Remove excess blank lines from source code to make files more compact for version-control diffs.
- Log trimming — Strip blank lines from log files to reduce file size for easier searching and transfer.
- Config cleanup — Remove empty lines from YAML or JSON configs to keep configuration files compact and standardized.
- Data preprocessing — Clean blank lines from CSV or text data to avoid empty records during data import.
- Text formatting — Remove excess blank lines from articles or documents to standardize paragraph spacing.
- Email paste tidy-up — Collapse the many blank lines left when copying from web pages before pasting clean content into email.
FAQ
Can it remove lines with only spaces or tabs?
Yes. Select the whitespace-only lines mode to also clear lines containing only spaces, tabs, and other invisible characters.
Can it trim leading and trailing spaces simultaneously?
Yes. Select the trim mode to remove empty lines while also stripping leading and trailing whitespace from each line.
Does it handle both Windows and Unix newlines?
Yes. The tool auto-detects CRLF (Windows) and LF (Unix) newlines, preserving the input newline format in the output.
Does it remove all empty lines or just extras?
By default it removes all empty lines. To keep single blank lines as paragraph separators, merge consecutive blanks first.
Will very large text run slowly?
Lines are processed sequentially, so tens of thousands of lines complete instantly; for extremely large text paste in batches and watch browser memory.
Is my data uploaded?
No. All processing runs locally via regex matching with no network requests, safe for sensitive text.
