Remove Empty Lines
Strip blank and whitespace-only lines from text.

Cleaning Up Whitespace-Heavy Text
Copy-pasted content often arrives with stray blank lines between paragraphs or list items. This tool removes every line that is empty or contains only spaces and tabs, collapsing your text into a tidy block. Optionally trim the leading and trailing spaces on the remaining lines too. Processing is instant and fully client-side.

What this tool is used for
- Tidying a list that has picked up blank lines from copying.
- Removing the trailing blank lines a spreadsheet export leaves.
- Compacting a file before an import that would read a blank line as a record.
- Cleaning up text pasted from a PDF with paragraph gaps.
- Removing whitespace-only lines that a parser treats as records.
Frequently Asked Questions
- What counts as an empty line?
- Two different things, and the distinction matters: a truly empty line has zero characters, while a blank line may contain spaces or tabs. A filter checking only for zero length leaves whitespace-only lines behind, which look identical.
- Should I remove all blank lines or collapse them?
- Depends on the format. Markdown needs a blank line between paragraphs, so removing all of them destroys the document — collapsing runs of blanks to one is usually the right operation. Removing all suits lists and data.
- Are trailing newlines affected?
- A file conventionally ends with exactly one newline — POSIX defines a line as ending with one, and many tools warn about 'no newline at end of file'. Stripping it can produce noisy diffs, so it is usually preserved.
- What about different line endings?
- A file with CRLF endings has \r before each \n. A line containing only \r is not empty by a naive test but appears blank. Normalise line endings first, or empty-line removal behaves inconsistently across platforms.
- Does this affect code formatting?
- It can break it meaningfully. Python does not care about blank lines inside a block, but YAML and Markdown do, and many style guides mandate blank lines between functions — so blanket removal is rarely right for source files.
- Does a line of only whitespace count as empty?
- It should for most purposes, but it is a distinct case — a line containing spaces or a tab is not zero-length, and a tool matching only `^$` leaves it behind. That is why apparently-blank lines survive a naive pass.
- What breaks if blank lines are removed from Markdown?
- Almost everything structural. A blank line separates paragraphs, ends a list, and terminates a code block — remove them and a document collapses into one run-on paragraph with its formatting reinterpreted.
Common errors and gotchas
- Removing blank lines that separated paragraphs, which merges them into one block.
- Overlooking whitespace-only lines, which look blank and are not.
- Removing the blank line a format requires, such as before a Markdown list.
- Collapsing blank lines inside a code block where they were deliberate.
- Losing the blank line that separated a header from a body.
