How to use Remove All Empty Lines
- 1. Paste your text. Enter the multi-line text you want cleaned into the input pane, such as a document with scattered blank lines or a log with gaps between entries.
- 2. Decide how to treat whitespace-only lines. Turn on Treat whitespace-only lines as blank if lines containing only spaces or tabs should also be removed, not just lines that are completely empty.
- 3. Copy the compacted text. Copy the result from the output pane, where every blank line has been removed and the remaining lines sit directly next to each other.
When to use Remove All Empty Lines
Remove All Empty Lines deletes every blank line from a piece of text, compacting it so remaining content sits together without gaps. It's for cleaning up documents, code and pasted lists where blank lines are clutter rather than meaningful structure.
- Compacting a config file after edits. Repeated editing of a config file left several blank lines scattered through it. Removing them tightens the file back up before committing the change.
- Cleaning a list exported with gaps. An export tool inserted a blank line between every item in a list you meant to paste directly into a script. Removing the blanks gives you a clean, contiguous list.
- Tidying a document copied from a PDF. Text copied out of a PDF often carries extra blank lines from page breaks and headers. Removing them, including whitespace-only ones, produces continuous readable paragraphs.
- Preparing code for a line-count-sensitive check. A code review tool flags unnecessary blank lines. Running a snippet through this tool first shows you exactly what it looks like with every blank line stripped out.

About the Remove All Empty Lines tool
Remove All Empty Lines does its work locally, right in the browser. Delete every blank line from a string. There is no upload step, no queue and no account, and your data never travels over the network.
It belongs to the String Tools collection on EditSafely, a set of 159 small, focused String utilities that share the same instant, private workspace.
You can shape the output with the Treat whitespace-only lines as blank setting, and the result refreshes the moment you change it. A worked example further down the page shows exactly what the tool produces for a real input.
Running locally also makes the tool fast and dependable: results appear as you type or drop a file, there is no server outage that can take it down mid-task, and confidential data can be processed without a second thought.
Frequently asked questions
Does Remove All Empty Lines cost anything?
Yes, it is completely free. All 2,658 tools on EditSafely work without an account, a subscription or usage limits.
Is it safe to paste sensitive or confidential data?
No data leaves your device. The whole tool is JavaScript that runs inside your browser tab, so there is no upload, no server-side processing and no log of what you did. If you disconnect from the internet after the page loads, it keeps working.
How much text can I process at once?
There is no fixed limit. Because the work happens on your own device rather than on a shared server, the practical ceiling is your machine's memory, which comfortably handles inputs far larger than typical online tools allow.
Do I need to sign up or install anything?
Nothing to install and no account needed. Open the page in any up-to-date browser, including on a phone or tablet, and the tool is ready.
How do I use the result?
The output panel has a one-click copy button, and you can keep refining the input while you work; the result updates in place as you type.
