Empty Line Remover

What counts as an empty line?

An empty line is a line that contains no characters at all: two line breaks in a row with nothing between them. A blank line looks identical on screen but actually holds invisible whitespace, spaces, tabs, or non-breaking spaces left behind by an editor or an export tool. Most cleanup jobs need both kinds gone, which is why the option to treat whitespace-only lines as empty is switched on by default.

If you specifically want to keep lines that contain only spaces, for example inside preformatted text, untick that option and the tool will only delete lines that are truly empty. The tool handles Windows, Mac, and Unix line endings automatically, so it does not matter where the text came from.

Why does pasted text fill up with empty lines?

Empty lines usually multiply when text moves between formats. Copying from a PDF often inserts a break after every printed line and a second one between blocks, so a tidy paragraph arrives with gaps everywhere. Website articles carry spacing that HTML hid from you, and it becomes visible the moment you paste into a plain editor.

Exports are another common source: chat transcripts, subtitle files, server logs, and CSV dumps frequently separate every entry with an extra newline. Word processors do it too, because many templates use an empty paragraph instead of proper spacing styles. One or two stray gaps are easy to fix by hand. Two hundred of them are not, and deleting them one by one in a long document is exactly the kind of mechanical work a browser can do for you in a few milliseconds.

How to remove empty lines from text

1. Paste your text into the box above. The character and line counts update as you paste.
2. Pick a mode. Remove all empty lines is on by default. Switch to Keep one blank line between paragraphs if you want paragraph spacing to survive, and leave Also remove whitespace-only lines ticked so lines full of invisible spaces are cleaned too.
3. Click Remove Empty Lines and copy the result. Check the live before and after counts, then copy the cleaned text with one click.

Before and after

Here is a short example. The input below has three real lines of content buried between five empty or whitespace-only lines, including one that holds nothing but spaces:

With Remove all empty lines selected, the result is the three content lines with nothing between them. With Keep one blank line between paragraphs, each gap collapses to a single empty line instead, so the notes stay visually grouped. The counters above the result tell you exactly how many lines were removed, so you can sanity-check the output before you copy it.

Remove every empty line, or keep paragraph spacing?

Which mode you want depends on where the text goes next. Remove all empty lines produces one continuous block of lines with no gaps, which is what you usually need for spreadsheets, keyword lists, code snippets, log analysis, and any place where each line is a record.

Keep one blank line between paragraphs is gentler: it deletes the clutter but leaves a single empty line wherever there was at least one, preserving the visual structure of prose. Use it for articles, essays, emails, and documentation, where paragraphs still need to breathe.

In both modes the whitespace-only toggle decides whether a line holding just spaces or tabs counts as empty. Leave it on unless you are cleaning preformatted text where those lines carry meaning, such as ASCII art or indented code blocks.

Where this tool helps most

The same cleanup shows up in very different jobs:

When you should keep your blank lines

Not every blank line is garbage, so it is worth a two-second check before you flatten a document. Markdown needs an empty line between paragraphs, otherwise separate paragraphs merge into one. Python code uses blank lines to separate functions, and style checkers even enforce them. YAML files, poetry, song lyrics, and postal addresses all use vertical space deliberately.

In those cases, choose Keep one blank line between paragraphs instead of removing everything: you still get rid of accidental double and triple gaps, but the intentional structure survives. And because everything runs locally and nothing is saved, you can simply press Clear and paste again if a result is not what you expected. The original stays untouched in your clipboard or source file.

A safer workflow for long documents and lists

Keep the source open while you clean. Paste a copy here, choose the least aggressive mode that solves the problem, and compare the line counts before and after. A large reduction can be correct for an export full of empty rows, but it is also a signal to inspect the first, middle, and last few lines before replacing your original. The counter is a quick check, not proof that every removed line was accidental.

For prose, start with Keep one blank line between paragraphs. Read two or three paragraph boundaries in the result, then use Remove all only if the destination truly expects one record per line. For spreadsheets and keyword lists, check that wrapped cells did not create meaningful continuation lines. An empty-looking row may separate sections, while a whitespace-only row may come from formatting and be safe to remove.

If the input is extremely large, work in sections that you can review. The processing stays in the browser, but a smaller section is easier to compare and undo in the source application. Remove empty lines before running punctuation or sorting tools, because that leaves a simpler list for the next step and makes later counts easier to explain. Each tool should make one visible change, followed by a quick review, instead of several irreversible edits at once.
