About This Blank Line Remover
Blank lines creep into text from all sorts of sources: pasting from PDF exports, copying from web pages, AI-generated content with extra spacing, terminal output, or just careless formatting in a long document. Removing them manually is tedious; this tool does it in an instant.
Remove All Blank Lines is the most aggressive mode — every line in the text that contains nothing (or only whitespace) is stripped out, leaving a compact block of content with no gaps. This is the right choice for cleaning up lists, data exports, and unformatted copy.
Remove Leading Blank Lines only strips empty lines from the very beginning of the text. Remove Trailing Blank Lines only strips them from the end. These modes are useful when you want to clean up edges without touching internal blank lines that may be intentional — for example, blank lines separating paragraphs or code blocks.
Trim Whitespace from Each Line is an independent option that strips leading and trailing spaces and tabs from every line in the text. It does not remove lines — it simply ensures no line has invisible padding at its edges, which is common in copy-pasted content and code.

Frequently Asked Questions
What is a blank line?
A blank line is any line in a text document that contains no visible content. This includes completely empty lines (nothing at all between two newline characters), as well as lines that appear empty but actually contain invisible whitespace characters like spaces or tabs. Both types are treated as blank by this tool, especially when the "Trim whitespace from each line" option is enabled.
What is the difference between blank and empty lines?
Technically, an empty line contains absolutely no characters between two newline characters. A blank line is broader — it includes lines that contain only whitespace (spaces, tabs) that appear visually empty but are not truly empty at the character level. In everyday usage, both terms are often used interchangeably. This tool handles both: by default it removes lines that are either completely empty or contain only whitespace characters.
Will this remove lines that only have spaces?
Yes. The tool treats any line consisting entirely of whitespace characters — spaces and tabs — as blank and removes it. This is the most common behavior users expect when cleaning pasted text or data. If for some reason you need to preserve whitespace-only lines, the current options do not support that use case, as such lines carry no visible or semantic value in plain text.
Does it work on code?
Yes. Blank line removal works on any plain text including source code in any language. It is commonly used to clean up code pasted from documentation, PDFs, or AI output. For code, use caution with "Remove All Blank Lines" since blank lines often serve as visual separators between logical blocks or functions. In those cases, "Remove Leading Only" or "Remove Trailing Only" is safer — it cleans up the edges of a block without disturbing internal spacing.
