Remove empty lines from your text —exactly the way you define "empty."
Paste your text, choose which kinds of blank and whitespace-only lines to treat as empty, then remove or collapse them in one click — without touching the formatting of everything else.
Advanced options
Runs entirely in your browser. Nothing is uploaded.
Built to fix what other tools skip
Most empty-line removers only do one thing: strip lines with zero characters. Real text isn't that clean.
Configurable whitespace rules
Decide exactly what counts as an empty line — space-only, tab-only, or mixed whitespace — instead of a one-size-fits-all strip.
Runs entirely in your browser
Your text is processed locally. Nothing is uploaded to a server, logged, or stored — safe for code, credentials, and client data.
Remove or collapse
Strip blank lines completely, or collapse long runs down to exactly the number you want — handy for tidying code and markdown.
No clutter, no login
One tool, done well. No account walls, no ad-stuffed sidebars, no unrelated directory of hundreds of tools to wade through.
How it works
Paste or drop your text
Type directly, paste from your clipboard, or drag in a .txt file.
Configure the rules
Choose which kinds of blank lines to treat as empty, and whether to remove or collapse them.
Copy or download
Grab the cleaned result with one click, or download it as a .txt file.
Where this comes in handy
Cleaning up code
Paste-formatted code often picks up stray blank and whitespace-only lines from editors or copy-paste. Strip them without touching indentation.
CSV & log exports
Exported reports and log dumps frequently include blank separator lines. Remove them before importing elsewhere.
SQL dumps & config files
Trim blank lines from SQL scripts or config files while keeping meaningful indentation and structure intact.
Copy-pasted documents
Text copied from PDFs or word processors often carries extra blank lines. Clean it up before publishing or sharing.
Markdown
Collapse long runs of blank lines down to one, keeping your Markdown readable without stripping intentional spacing entirely.
The Complete Guide to Removing Empty Lines from Text
Everything this tool does, and why, in plain language.
Whitespace has a way of piling up. Copy code out of a tutorial, export a report from a spreadsheet, or paste a page out of a PDF, and you'll almost always end up with extra blank lines, stray spaces, or a row that's nothing but a tab character. None of it is visible until you actually need the text to be clean — for a script that expects tight formatting, a document you're about to publish, or a config file a parser is about to choke on. Remove Empty Lines exists to fix exactly that: a fast, free way to remove empty lines from text online, without changing anything else about the content. Paste your text, tell it what counts as "empty," and get back the same text — minus the clutter. No formatting is reflowed, no indentation is touched, and none of the lines you keep are rewritten in any way.
What Actually Counts as an "Empty" Line?
Most tools that claim to delete empty lines online only handle the obvious case: a line with literally zero characters. In practice, that's a small slice of the problem. Text copied from a word processor or exported from a spreadsheet often leaves behind lines that look empty but technically aren't — a single space, a run of tabs, or a mix of both, left over from indentation that no longer points at anything. If a tool only strips truly empty lines, those invisible lines survive untouched and the text still looks broken.
That's why this tool treats "empty" as something youdefine. You can remove empty lines that contain nothing at all, delete blank lines made up of spaces only, tab-only lines, or lines that mix different kinds of whitespace — each rule is its own toggle, so you only remove what you actually want gone, and nothing else in the line is touched.
How to Remove Empty Lines Online in Three Steps
Using the tool doesn't require an account, a download, or any setup:
- Paste your text — or drag in a .txt file — into the input box.
- Choose your rules: which kinds of blank lines should be treated as empty, whether to trim trailing whitespace, and whether to remove blank lines entirely or collapse long runs down to a number you choose.
- Click "Remove empty lines" (or press Ctrl/Cmd + Enter) and copy or download the result.
That's the entire workflow for removing empty lines online — no waiting on an upload, no ads to click past, no login wall. The output updates instantly, with a live count of how many lines and characters were removed, so you can see exactly what changed before you copy it anywhere.
Remove Completely, or Collapse Blank Runs
Sometimes you want every blank line gone — cleaning up a minified script or a CSV export, for example. Other times, deleting every blank line makes text harder to read, not easier: a Markdown file or a block of code often uses a single blank line on purpose, to separate paragraphs or logical sections.
This tool supports both. "Remove all blank lines" strips every line that matches your whitespace rules, no matter how many appear in a row. "Collapse runs" keeps those same rules but limits every run of blank lines down to a number you set — so five blank lines in a row become one, and your document keeps its structure without the clutter.
Why Remove Blank Lines Online Instead of by Hand
Manually scanning a large file for blank lines, tab-only rows, and stray spaces is slow, and it's easy to miss whitespace you can't even see. A find-and-replace with a regular expression can work, but it means knowing the right pattern for every whitespace variant — and one mistake in that pattern can delete content you meant to keep.
An online blank line remover does the same job in one click, consistently, without touching the content of the lines you keep. And because everything runs locally in your browser rather than on a server, there's no reason to hesitate before pasting in source code, internal documents, or anything else you'd rather not upload anywhere.
Common Places This Comes Up
People use this tool to remove empty lines from text pulled out of all kinds of places: code copied from tutorials or forums, CSV and log exports with blank separator rows, SQL dumps and config files, text lifted out of PDFs or word processors, Python or YAML files where stray whitespace can change how the file is parsed, and Markdown files that have picked up more spacing than intended along the way. If it's plain text and it has lines you don't want, this tool can clean it up in seconds — with the original formatting of every line you keep left exactly as it was.
Free, Unlimited, and Nothing to Install
There's no word or file-size cap baked into the tool, no daily usage limit, and no account required to keep using it. Because the processing happens on your device instead of a server, the only real ceiling is how much your own browser can comfortably hold in memory — which, for the plain text this tool is built for, is normally well beyond anything you'd paste in by hand. Bookmark the page and use it as often as you need to remove empty lines from text online, for free, without ever creating an account.
However your blank lines got there, you don't need to hunt them down by hand or hand your text to a server you don't control.Paste it in above, set your rules once, and remove empty lines from text online for free — as many times as you need, with no limits and no sign-up.
Frequently asked questions
About this tool
What exactly counts as an empty line?
By default, a line with zero characters is always treated as empty. You can also choose to treat lines that contain only spaces, only tabs, or a mix of whitespace characters as empty — each is a separate toggle, so you control exactly what gets removed.
Does this tool upload or store my text?
No. All processing happens locally in your browser using JavaScript — your text is never sent to a server, logged, or saved anywhere. You can disconnect from the internet after the page loads and the tool still works.
Can I keep some blank lines instead of removing all of them?
Yes. Switch "Blank line handling" to Collapse and set how many blank lines should remain wherever there's a run of them — useful for tidying spacing in code or Markdown without flattening it entirely.
Will this change the indentation or content of my other lines?
No, unless you turn on "Trim trailing whitespace," which only removes trailing spaces/tabs at the end of lines that are kept — leading indentation and line content are left untouched.
Does it handle Windows (CRLF) and Unix (LF) line endings?
Yes. With "Preserve line endings" enabled, the tool detects whether your input mostly uses CRLF or LF and keeps that convention in the output. Turn it off to normalize everything to LF.
Is there a file size limit?
There's no hard limit — everything runs in your browser, so it's bounded by your device's memory rather than a server upload limit. Very large files (tens of megabytes) may be slower to process depending on your device.
How-to guides
How do I remove empty lines online?
Paste your text into the box above, leave the default whitespace rules on, and click "Remove empty lines" (or press Ctrl/Cmd + Enter). The tool strips every blank line — including ones with only spaces or tabs — instantly in your browser, with nothing uploaded to a server.
How do I delete empty lines?
The fastest way is to paste the text into a dedicated tool like this one and click a button — it handles every whitespace variant at once. If you're editing inside a specific app instead, most editors support Find & Replace with regular expressions to match and delete blank lines (see the Word, Notepad, and Notepad++ answers below for exact steps).
How do I remove blank lines online?
Use the box at the top of this page: paste or drop in your text, choose whether to remove blank lines completely or just collapse long runs of them, then click "Remove empty lines." Everything runs locally in your browser, so nothing you paste is ever uploaded.
How do I delete empty lines online?
Open this page, paste your text, and click "Remove empty lines." You can enable "Show removed lines" first to preview exactly which lines will be deleted before you commit, then download or copy the cleaned result.
How do I delete all blank lines in Word?
Word has no one-click button for this, but Find & Replace can do it: press Ctrl+H, click More, enable "Use wildcards," set Find what to ^13{2,} and Replace with to ^p, then click Replace All — this collapses every run of blank lines down to one. To remove blank lines completely, run Replace All again with Find what set to ^p^p and Replace with set to ^p until no more replacements are made. Word's wildcards can't easily catch lines that only contain spaces, though — for that, pasting the text into an online tool like this one is faster and more reliable.
How do I delete a blank line?
For a single blank line, click at the start of it and press Backspace (or click at the end of the line above it and press Delete) to merge it away. That works in virtually any text editor or word processor. For removing many blank lines at once across a whole document, use Find & Replace or paste the text into an online remover instead of going line by line.
How do I remove empty lines?
Paste your text into the tool above and click "Remove empty lines" — it deletes every line with no content, and you can optionally extend that to lines containing only spaces, tabs, or mixed whitespace. If you'd rather not use a browser tool, your text editor's Find & Replace with regular expressions can do the same job manually.
How do I remove extra empty lines in Word?
"Extra" usually means collapsing multiple consecutive blank lines down to one, rather than removing all spacing. In Word, press Ctrl+H, click More and enable "Use wildcards," set Find what to ^13{2,} and Replace with to ^p^p (to leave one blank line between sections) or ^p (to leave none), then Replace All. This tool does the same job with a "Collapse runs" option where you pick exactly how many blank lines should remain, without writing any wildcard syntax.
How do I remove empty lines in Notepad?
Classic Windows Notepad has very limited Find & Replace with no regular-expression support, so there's no built-in way to remove blank lines in bulk. The newer Notepad (Windows 11, with the regex toggle in Find & Replace) can do it: enable "Use regular expressions," search for ^\s*\r?\n, and replace with nothing. If your version of Notepad doesn't have that option, it's faster to paste the text into an online blank line remover instead.
How can I remove blank lines from a text?
Paste the text into the input box above and click "Remove empty lines." You can choose whether space-only and tab-only lines should count as blank too, and whether to strip every blank line or just collapse long runs — then copy or download the result.
How do I remove all blank lines in Notepad++?
Open Find & Replace (Ctrl+H), switch Search Mode to "Regular expression," set Find what to ^\s*$\r?\n, leave Replace with empty, and click Replace All — this deletes every line that's empty or contains only whitespace, including its line break. Notepad++'s regex engine handles this well natively; this tool gives you the same result without writing a regex, plus a preview of exactly what will be removed first.
