Remove Blank Lines

Any line that is empty or contains only spaces and tabs is treated as blank and removed. Lines with visible content are always kept, in their original order.

Pasted text, exported data, and double-spaced documents often carry empty lines between every paragraph or row. Removing them compacts lists, tidies code, and prepares data for import where blank rows would cause errors.

No. This tool only removes whole blank lines. To collapse repeated spaces use Remove Extra Spaces, and to drop repeated lines use Remove Duplicate Lines.

No. The lines that contain content keep their own line breaks: only the empty lines between them are deleted.

The tool trims each line before testing it, so a line holding only spaces or tabs counts as blank and is deleted exactly like a truly empty line. This catches the invisible whitespace that pasted text carries. For example, an input of "item one", a line containing a single space, then "item two" comes back as two adjacent lines: the space-only line looked empty on screen and was removed, leaving no hidden gap.

No text is lost, but the empty separator lines between paragraphs are deleted on purpose, so the visual gaps close up. In plain prose that is cosmetic; in Markdown or HTML source the blank line is structural, and renderers merge adjacent paragraphs into one block once it is gone. For example, two Markdown paragraphs separated by a single blank line render as one paragraph after cleanup, so use this tool on lists and data rather than markup.

Every blank line is deleted, including the ones you added deliberately, because the tool cannot tell a purposeful section break from a stray gap. To recover the layout, restore the original text from your clipboard or source document and clean only the sections that need it. For example, a config file that used one empty line between sections comes back as a single contiguous block, so process each section separately and rejoin them with your own spacing.
