How to remove extra blank lines without changing text order
Remove multiple empty lines from copied text
Keep whitespace-only lines or treat them as blank
Example of removing extra blank lines from text
Copy or download text after removing blank lines
Remove extra blank lines from code and documents
Features explained
Maximum consecutive blank lines
Set maxBlankLines from 0 to 10,000. The default is 1. A value of 0 removes all consecutive lines recognized as blank, while higher values preserve up to the chosen number.
Whitespace-only line detection
Enable trimWhitespaceOnly to count lines containing only whitespace as blank. Disable it to count only truly empty lines. The setting affects which lines are filtered.
Copy cleaned text
Use Copy to place the processed text on your clipboard. The interface also has a Copied! label for the copied state.
Download the result
Use Download to save the cleaned text as a file. The available code confirms the download control, but does not specify the filename or extension.
Load an example
Load Example fills the tool with sample text so you can see how the blank-line settings affect the result.
Clear the text
Use Clear to reset the current text in the tool.
Character count
The interface includes a Characters label. The available processing logic does not establish exactly how its count is calculated.
Client-side processing
The text-processing logic runs in the browser without making a server request for the transformation. This does not establish the behavior of every surrounding application feature.
What can you use it for?
Clean up text copied from websites
Remove repeated blank lines that appear when you copy text from a webpage. Choose 0 or 1 depending on whether you want paragraphs to remain separated.
Organize notes and draft documents
Reduce excessive vertical gaps in notes, drafts, and plain-text documents while preserving the order of their nonblank lines.
Prepare code snippets for review
Reduce repeated empty lines in a code snippet before sharing it. Check the result afterward because some source formats use whitespace for readability or meaning.
Clean text before pasting into another app
Use the tool to remove repeated blank lines from text before copying the cleaned output into another editor or application.
Standardize paragraph spacing
Choose the maximum number of blank lines to keep between blocks of text instead of removing every empty line.

Benefits
- Keep control over how many consecutive blank lines remain.
- Preserve the order of all nonblank lines.
- Choose whether whitespace-only lines count as blank.
- Copy or download the cleaned result using the available controls.
- Run the text transformation in the browser without a processing server request.
Limitations
- The tool filters blank lines; it does not rewrite or correct your text.
- The maximum setting is limited to values from 0 to 10,000.
- With trimWhitespaceOnly enabled, lines containing only whitespace are treated as blank and may be removed.
- The output is joined using newline characters, so the original line-ending style is not preserved as a separate setting.
- The processing logic does not establish a specific downloadable filename or extension.
- Client-side transformation does not prove that every surrounding application feature is offline or that no data is handled elsewhere.
How your text is processed
The removeExtraBlankLines transformation runs on the client side in the browser, and the supplied processing logic makes no server request to transform the text. This supports a client-side processing claim, but the available code does not establish the behavior of analytics, hosting, browser extensions, or every other application feature.
Tips
- Start with the default maxBlankLines value of 1 if you want one blank line between text blocks.
- Choose 0 when you want to remove every line recognized as blank.
- Keep trimWhitespaceOnly enabled if lines containing spaces or tabs should also count as blank.
- Disable trimWhitespaceOnly if only lines that are exactly empty should be removed.
- Use Load Example to check the result before processing your own text.
- Review code snippets after cleanup if whitespace matters to your project.
Frequently asked questions
How do I remove extra blank lines from text online?
Paste your text into Input Text, choose the maximum number of consecutive blank lines, and inspect Cleaned Text. The default maxBlankLines value is 1, which keeps no more than one consecutive blank line.
Can I remove all blank lines from a text file?
Yes. Set maxBlankLines to 0 to remove every line the tool recognizes as blank. With trimWhitespaceOnly enabled, lines containing only spaces or tabs also count as blank.
How many blank lines can I keep between paragraphs?
Up to 10,000 consecutive blank lines can be retained according to the option's allowed range. The default is 1. The actual output can contain fewer blank lines if the input has fewer.
Does removing extra blank lines change my text?
No. The processing logic filters blank lines and preserves the order and contents of nonblank lines. It does join the resulting lines with newline characters, so the original line-ending style is not preserved separately.
What does trimWhitespaceOnly mean when cleaning text?
It determines whether whitespace-only lines count as blank. When enabled, a line containing spaces or tabs is treated as blank. When disabled, a line is blank only if it contains no characters.
Can I clean copied text without uploading it?
Yes, the text transformation runs on the client side and does not need a server request for processing. This describes the supplied transformation logic, not every possible data-handling behavior of the surrounding application.
How do I remove empty lines from code snippets?
Paste the snippet into Input Text and set maxBlankLines to the desired value. Check the output before using it, because whitespace can matter in some programming languages, configuration files, and text formats.
Can I copy the cleaned text into another app?
Yes. Use Copy after reviewing Cleaned Text, then paste the result into your chosen application. The interface also provides Download if you prefer to save the output as a file.
What happens when I click Load Example or Clear?
Load Example fills the tool with sample text so you can test the settings. Clear resets the current text. These controls are available in the interface, although the supplied processing case does not define every detail of their UI behavior.
